Investigation of the Flectrical Characteristic* of the Welding Are in
Argon. A. Ya. Brodsky WW 0. M. Tikhodw (Avtog. Delo, 1949P Mv 1-3)--
(in of invesittation carried out with the tungsten/
cbreadm-nIckel, are In an atmosphere of argon, the following functions
were deduced: T a f(l), when I is constant and V - f(l) when I is conmmt
(V a voltage, I w current, 1 a loq[th of thow arc.) The relationship
V a f(l) can be tzkon an linear for practical purposes without serious
error. The potential gradient is about 9-10 Vs/c~,. The effect of impuri-
ties in the argon on the voltapo of the are was also studied: with the
tungsten are, other things being equal, the voltage would be 1-2 V. higher
using commercial argon (86*6%) as compared with purIfted argon (97%).'
Fy taking advantage of thin, it appears possible to regulate the beat
intensity of the welding are by varying the quantity of impurities in
the argon.-W.J.X.

reversible deformation, caused by processes of oxi-

PERIODICAL: "Svarochnoye*Proizvodstvo", 19579 # 7, pp 22-24 (USSR)
ABSTRACT: The article deals with the "tank-welding" method which had
been suggested long ago by N.G. Slavyanov and has been used in
the USSR for 3-4 years in butt-welding of large-diameter rein-
forcement bare for reinforced concrete constructions.
Welding by this method on single phase current and with one
electrode with a steel croup serving as mold, is now practiced
at the experimental melding plant of the "L4HIMMqH11. This
method was also used for reinforcement welding at the Kuybyshev
Hydroelectric Plant (Kuybyahevgidrostroy). The Technical
Conditions "TY 19-51" of the Ministry of Power Pl~nts require a
strength - limit not below 42 kg/MM2 for butt Joints of profile
bars of steel 'TT, 5"~conditional stresses are meant, determined
by dividing the breaking stress by the cross section area of the

where 50 bars welded at the Kuybyshevgidrostroy have been
tested - only 20 of the 50 tested butt joint5 disrupted under
load corresponding to stresses of 42-43 kg/mm , JO joints broke
at 38-41 kg/mmie, and 20 joints - at 25-37 kg/mm . 90 % of the
joints which failed to pass the test contained defects in the
form of non-fusion over 30 to 60 % of the cross-section area$
causod by.1slagging" of the bar butts, i.e. solidifying of slag
on the butts during the initial stage of tank-welding.
At Stalingradgidrostroy, 21 % of 503 welded reinforcement bars
made of steel "Cr.5" with a diameter of 22-80 mm, did not pass
the test, mainly due to non4usion and "slagging" (mostly in the
bottom portion of the joint). According to data from the
Kakhovskaya Hydroelectric Plant, non-fusion and slag inclusions
were also the most frequent defects of butt joints. Electrode
combs which were used for the pnrpose of increasing productivi-
ty of work, led to even more "slagging" when welding was perform-
ed on the aforementioned steel cramps.

PERIODICAL: Avtomaticheskaya svarka, 1958, Nr 3, pp 50-56 (USSR)
ABSTRACT: Thus far, reinforcement frames for concrete structures were
are-welded. Experience has shown that contact spot welding
is cheaper and more cfficient in the production of reinforce-
ment frames without diagonal links. Hcwever, joining three
or five periodical-profile "St 5"-steel bars into cluster
joints by oontact spot welding entails metal hardening at
the joint, caused by fast heating and subsequent fast cool-
ing. The article gives a detailed description of experi-
ments carried out for the purpose of eliminating this hard-
ening. Engineer V. YakovlevR took part in the experiments.
The developed technology consists in subsequent heating of
the joints to a definite temperature between the electrodes
of the welding machine and in slow cooling. Details of tech-

ABSTRACT3 The MVTU method of N.V. Prokhorov and S.A. Kurkin (with
Kurkin's specimen as is shown in figure 1) and the VNII Min-
transmash method of L.A. Fridlyand and K.I. Timofeyev (with
the use of special test machine) were tested on steel "14G2"
and "14KhGS" (GOST 5058-57-standard) and on killed sieel
'IMSt.3". The test results differed. The author points out
the faults of the Kurkin specimen, which does not reproduce
the actual conditions of the deformation of metal in the pro-
cess of welding. It is concluded that the VNII Mintransmash
method clearly reveals the changes in the strength of metal
welded to different steels, with the "UP2/45" and "OMM-5"
electrodes. It is suitable for revealing the technological
strength of intercrystalline layers, conditioned by their

ary short-circuit current, electrode deposition, axial load
on the electrode and dimensions of a copper ring serving to
form the electric rivet head. Tests proved that the strength
of weld joints increased with larger electrode diameters
and increased --amber of welded spots. Further investiga-
tions of the new method are being performed and equipment

ABSTRACT: The article presents the results of tests for weld-
ability, made with steel type 15GS. For the investi-
gation three samples of steel 15GS were taken, which
were produced by the factory "Krasnyy Oktyabr"I (Red
October). The contents of carbon in one sample were on
the lower limit of the GOST-5058-57-Standard and in
.another sample nearer the higher limit. The silicon
concentration of both samples was lower than that de-
manded by the standard. The third sample had a medium
carbon concentration, while the silicon content was on
the lower limit. The fluidity limit of the steel with
the lowest carbon concintration was at a thickness of

strength of the samples with low and medi9- carbon 2
concentration was at a temperature of - 40 3 Kgm/cm
lower than demanded by the standard. The results of the
tests were compared with the data of a parallel test,
made with steel NL2, where also three samples were used.
Here the carbon concentration was nearer the higher
limit. Schedule 1 shows the exact chemical composition
of both types and their mechanical qualities, given by
Candidate of Technical Sciences P.I. Sokolovskiy. For
the welding electrodes type UP-2/55. SY-11 and UP-2/45
were used. For the test of sensibility against "ten-
sion concentrator" the tests made by Kintzell with 30
mm thick samples with sharp incisions (r=O.1 mm) were
used. The results showed, that the samples with high
and medium carbon concentration had a higher sensibili-
ty within the zone of thermic influence than steel type
ITL-2. The sample with low carbon concentration and low
Card 2/4 silicon concentration was equal to the corresponding

sample of steel NL2. In other tests it could be seen,
that steel 15GS with 0.1V C and 0.55",f Si does not
have a higher reaction $o the natural tension concen-
trator than steel N12. Steel with medium carbon concer,
tration and a low silicon concentration cannot be wel-
ded satisfactorily, but this steel can be welded well
with a minimum carbon and silicon concentration. It
could be seen in the tests, that steel type 15GS in a
composition corresponding to standard GOST-5058-57 is
not to be used for welded building constructions.
Steels with changed chemical compositions shall be tes-
ted the same way later on. There are 6 graphs, 4 dia-

ABSTRACT: Experiments were carried out with aluminum allo7ski
improvable by heat treatment, with the use of argon

elements. The purpose was to check the weldability
of the alloys in such.thickness, since they proved
not weldable in 1-3 mm. thickness, i.e. the strength
of welds was too low and they evelope~ cracks. ~

given. The following conclusions were made-
1) The "kMgA-M" and "AMg6l' can be recommended for
use in welded structures but the "AMg6" developed,
pores in elements over 5 mm in thickness, and
means must still be found to do away with porosity.
The welds of "AMgA-M" had.the same mechanical -
strength as the base metal. In 10 mm thickness,
welds of the "AMg6" had..the-strength of about 70%
of the base metal and welds of the "AMg6" and 5 mm
thickness was between 80 and 95%. 2) Welds in
alloys improvable by heat treatment made by elec-
tro(Ies of the IIAM&I.and "AV-K" alloy developed
no cracks although the welded specimens were fixed.

into the parent metal. 3) The strength of butt
joints in elements 10 mm thick welded with the "AMg6"
wire was about 60% of the base metal strength. In
elements of the "V95A-T" 10 mm thick welded by the
J'AMg6" wire, strength was only 50% of the base me-
tal. 4) Heat-affected zone (determined by distri-
bution of hardness) spreads differently in dif-
ferent types and grades of alloys. In the "AMg6"
it did not depend on the arc power in the range of
6000-13,000 kalories per centimeter weld length
but at more intense arc heat the zone of lowered
hardness spread further, and the hardness in metal
dropped. In heat-susceptible "Dl6A-T" and "V95A-T"
the zone of heat effect and lowered hardness was
considerably greater and depended directly on the

TEXT-. In Reference 1, the authoi~ investigated a new are spot welding method
which differs from conventional processes insofar as the weld Joints are produced
without piercing the upper element being welded, at a thickness of 10 mm and more.
Further experimen-;.s to develop this method were carried out by laboratory assistant
j under the supervision of the author. Information is presented
V.A. Sinyr-R2:Eki
on the resultBobtained. The experimental investigation was carried out with 6; 8;
10 and 20 mm thick (MST.3) strip steel and %(T,~' (BST-5) steel and
"WRV-13/55A" (ITONI-13/55A) (d = 4) and "~OHV-13/15.5!' WOK-13/55) or "ifl 20
(UP22) (d=5 and 6 nun) electrodes. A laboratory welding device shown in Figure 1
was used. The are was fed from a "TCA-1000" (TSD-1000) transformer. The are
was excited during the Initial welding stage by a "0(-R3 -1" (03PZ-1) oscillator.
The deep-fusion welding process is divided into 5 stages; ' 1) ignition of the arzo;
2) beginning of the metal fusion and format.ion of a closed cavity, 3) fusion of

the metal to the required depth; 4) filling of the fused ewvity; 5) formation
of a reinforcee head. Changes in the current and voltage depend on the conditions
of the electrode tip and of the coating lip formed on the electrode tip during
the first are spot welding. An oseillogram is given representing the current
and voltage during the initial fusion period fcir three cases- 1) the contact
between the electrode and the surface being welded is a spot; 2) the height of
the lip is 2-3 mm; 3) the contact surface between the electrode tip and the
metal is large. Characteristics of each stage are given, It is shown that
the use of a "nC -500" (PS-.500) are feed generator is unfit for deep fusion weld-
ing on d-c. By investigating the correlat-lon between the axial load on the
electrode and fusion characteristics, the author establishes that the axial load
exerts a pronoumed effect on the fasion depth. If the loads are below the limit
value increased axial load causes a greater fusion depth. A load approaching
the limit value reduces the depth of fusion. Under the effect of excess load the
electrode is bent- to an angle whose increased inclination reduces the strength of
the Coating. The presence of a gap between the elements being welded reduces the
strength of the-weld joints. The assembly of the elements must therefore be made
very Carefully. Tneir may-1-mum thickness, whic-h is 25 and 30 nLm, was determined
by tests with 20, 25 and 30 mm thicok upper. and 6 mm thick bottom plates made of
"14F" (140) sheet steel. The Jointa were free of defects, such as hot Cracks,

PERIODICAL: Svarochnoye proizvodst-vo, 1960, No. 10, pp. 22-24
TEXT: A method of two-electrode semi-automatio argon are welding of
aluminum alloys from one feed source was developed with the participation of
L. S. Livshits, Candidate of Technical Sciences, from VNIIST. It was intended to
attain thereFy an increase in the crystallization time of the seam met-al and a
higher welding efficiency. For this purpose the TlWff-9 (PShP-g)semi-automatic
machi.- f one-phase two-electrode welding was redesigned at the welding
_H!~3'1 ~ or
laborat'b'ry of the department of metal s i;ructures- at TsNIISK. The electric cir-
cuit of the machine remained the same, bu the electrode feed was modified'as
follows: the wires are fed through a flexible hose from two containers to the
pistol. From the hose thy are supplied to a pulling device consisting of a roll
with two semi-circular grooves and a pinion gear. Through a hollow pipe the
wires enter a copper aurrent-conducting tip with two eccentric apertures and are

then supplied through the tip to the welding area. The gap between the electrode
wires and their arrangement in respect to the symmetrical axis of the pistol
may be varied by turning the tip. The optimum gap between the wires was found
to be 2 mm. It was established by further experiments that the possibility of
regulation was of great importance in developing the welding technology, since
it affected the crystallization time of the welding pool, the width of the seam
and the penetration depth. Tests performed with AR4alloy pipes of 377 mm
external diameter proved the good quality of one-pass two-electrode argon-arc
welding under the following conditions: V-shaped unblunted chamfer of' the pipe
edges with angles of taper of 30 - 50 0; assembly of the pipes without a gap on
a backing ring with a shaping groove; welding with 380 - 400 amps current;
12 - 13 m/hour speed; 12 - 15 1/min argon consumption; 300 m/hr electrode feed
and 1.5 mm AMg wire diameter. The :wire is degreased and undergoes a special
etching treatment prior to welding. The 2ultimate strength of welds produved
by the described method is 19 - 22 kg/mm . The developed technology provides
for an extended welding current limit and increased coefficient of build-up
raising the efficiency of the process. Investigations showed that. mechanical

PERIUDICALt Beton i zhelezobeton, 1961, No. 1, pp. 28-30
TEXTt A.A. Ulesov and V.Ya. Dullkin have raised two questions in their ar-
ticle - one concerning the effectiveness of bath welding in general with re-
gard to butt joints of reinforcement rods - and the other on butt welding of
reinforcement joints in reference to steel of 30Xf-2C(3OKhG2S) grade. Ulesov
and Dullkin try to solve the question rationally by applying the character-
istics of bath welding of brand C/m-3 (St-3) and C,,,-5 (St-5) steel to
30KhG2S steel which is a mistake. The experience of Ulesov and Dullkin are
based on the production of monolithic reinforced (but not prestressed) con-
crete constructions, dealing with field welding of 80-90 mm rods made from

" -4 (St.4) and Om -5 (St.5) carbon steel, which belong to the easily weld-
able grades. On the other hand there exist steel grades, as shown in the
table issued by Mashgiz in 1951, which are only weldable if thermically
treated before or after the welding process. Such are the steels of 30x rc
(30KhGS) and 35x rc (35KhGS) grade. Since thermic treatment is not applic-
able on the site, the utilization of such high-grade low-alloy steel for
welding purposes in concrete reinforcement is prohibitive. In commenting on
the statements and proposals of Ulesov and Dullkin the authors of this ar-
ticle explain the reasons, why bath welding of the butt joints of reinforce-
ment rods is not to be recommended in reinforced concrete structures and ar-
rive at the following conclusionsi 1) Steel of 30 KhG2S grade from which
high-grade rods for prestressed reinforced concrete structural elements are
made, having a diameter of 10-32 mm belong according to rOCT 5058-57 (GOST
5058--57) to the number of difficult weldable steels. 2) The butt welding of
the joints of such rods can only be executed in plants, while resistance butt
welding appears to be the most progressive method of welding, 3) In the ab-

sence of resistance butt welding machines, reliable butt joints of rods from
30KhG2S steel can be obtained from are welding by the application of round
bars, in accordance with the technology contained in the "Directives", .
4) Bath welding of butt joints of rods from 30KhG2S steel does not ensure
sufficient strength and should therefore not be applied. 5) The utilization
of covers in butt welding of joints of rods from 30 KhG2S steel is permiss-
ible only if there are no other more progressive methods of welding avail-
able. In this connection TsNIISK has developed and introduced a certain num-
ber of methods of mechanized welding of rods made from steel of St-3, St.5,
25 r 2 C (25G2S), 35 I-C (35GS), 18 r 2 C (1 8G2S) grades etc (electroslag hand
welding and multi-electrode bath welding methods), TsNIISK is constantly en-
gaged in investigating and developing more progressive and more perfect means
(semi-automatic and automatic electroslag welding) for the general wel`!:g
method, as worked out by the Institut elektrosvarki im.Patona (Electrowelding
Institute im.Paton). There is 1 table and 1 Soviet reference.

TITLE: Effect of the argon-are welding conditions on the surface of welds
in the welding of aluminum alloys with consumable electrode
PERIODICAL: Avtomaticheskaya svarka, no. 3. 1961, 27 - 31
TEM The causes of wrinkled weld surfaces in welding aluminum alloy parts
in other than aircraft structures, i.e., elements of 5 - 10 mm and higher thick-
ness, were investigated in experiments. Welding was effected with an automatic
welder on Aft (AMg6) alloy with wire of the same alloy. Data of other investi-6
gations,are mentioned in which it was found that, if the welding current is raisad
above a'certain limit, it spoils the welds and makes the surface uneven, porous
and dirty. The "wrinkle" formation is explained by the pressure of tre arc on
the liquid pool and insufficient argon shielding, the formation of a thick oxide
film, and shifting of the film together with liquid metal into wrinkles. The
phenomenon has to be studied, for welding of thick parts in structures requires a
strong current. The effect was determined by the welding speed, are voltage an-

nozzle end and weld metal surface, internal diameter of nozzle, neck of electrode
wire, and diameter of electrode wire. The discussion of every parameter effect
is illustrated with a graph. It is stressed that the optimum argon consumption
is fbund for only one nozzle design, and should be corrected for various nozzles,
but the linear dependence stated between the optimum argon consumption and the
inner nozzle diameter will provide an aid for the selection of welding process
data. The conclusion is drawn that the maximum permissible welding current is
possible at the lowest practically possible welding speed, are voltage and space
between the nozzle end and weld surface, and at an optimum consumption (12 - 25
1/min with an inner nozzle diameter of 16 mm, or 22 - 46 1/min with 30 mm, and
nozzle incline angle of 800; an inner nozzle diameter in the range 16 - 40 mia and
the wire neck have slight and about equal effect. There. are 7 figures slid 4 So-
