TITLE: Selecting the Frequency of the Cur-rent for Low-Fre-
quency Contact (Welding) Machines
PERIODICAL: Avtomaticheskaya svarka, 1959, Nr 8, pp 18-24 (USSR)
ABSTRACT: This item treats the selection of the optimum welding
current frequency on the basis of a study of the fre-
quency characteristics of 4 universal contact welding
machines, and considering particularities of each type
of contact welding. The authors open with a broad
oi- line of some of the factors involved in operat
ing
'
contact welding machines at low frequencies. The fre-
quency of the welding current, it is stated, should
be selected with regard to: a) the greatest possible
reduction in power consumed by the machine; b) the
minimum possible increase in the weight of the welding
transformer; c) the most favorable effect on the tech-
nology of contact welding. Frequency characteristics
were calculated for 4 universal machines: the MTP-300
Card 1A for spot welding, the MShP-150 for seam welding, the

SOV/125-59-8-3/18

MRP-600 for relief welding, and the RSKM-320 for junc-
tion welding; characteristics were measured with the
machines short-circuited. A sinusoidal voltage, carry-
ing from 50 - 5 cps, was fed to the primary of the
welding transformer. Analysis of the frequency char-
acteristics obtained (Fig 1) shows that the character-
istics of impeaence changes relative to frequency for
the various machines are roughly the same. These re-
sults are briefly discussed further. These character-
istics Dermit calculation of the power of the machine
as a function of frequency. This is briefly discussed
in relation to various types of contact welding and
with regard to the resistance of the welded object
inserted in the secondary circuit of the machine.
Some results are presented and graphed (Figs 2,3).
The relationship between power and the weight of the
welding transformer is mathematically derived. The
authors conclude that, depending on the type of weld-
Card 2/4 ing, the frequency shoii1d lie in the range of 5 - 10

cps; for spot welding of light alloys and. relief
welding, 5 cps is considered best, and for point weld-
ing of steel and junction welding, 10 cps is best.
Lowering the welding current frequency also moans
that consumed power can be decreased from 2-5 times,
depending, on the type of welding. A significant in-
crease in the power factor of the machine also results,
Further decreasing the frequency does not give a sub-
stantial power gain and leads to an unjustifiable in-
crease in the weight of the transformer. In conclu-
sion the authors describe the waveform put out by the
simplest frequen,_zy and phase converters used in weld-,
ing which is close to a square wave (Fig 5), and its
effect in operation of the welding machine; it is
calculated that with such a waveform power is 11%
greater than with a sinusoidal wave.

TITLE: Three-Phase Converter for Prequencyp and Number of
Phases for feeding of Point-1,11elding Machines
PERIODICAL: Avtomaticheskaya svarka, 1959, Vol 12, Nr 5, (74)
pp 34-44 (USSR)
ABSTRACT: The article presents three- phase ionic converters
for frequency and phases number, which are used for
the feeding of point welding machines. Two basic types
of converters were constructed. One with an interme-
diate chain of rectified current. It had a cascade
combination between rectifier and inverter., which con-
verts the rectified current into alternating current
of the needed frequency.(Fig. 1). A shortcoming of this
scheme is the interval between positive and negative
current impulses at low frequencies. This lowers the
effective value of the welding current. The other one
is a converter with direct converting of frequency
Card 1/2 and phase number. This can easily be made to operate
in turn in opposite directions of the rectifier.

Three-Phase Converter for Frequency, and Number of Phase for Feeding
of Point Welding Machines
Thus the positive half-periods of low frequency cur-
rent can be formed by one rectifier, the negative half-
periods by the other one (Fig, 2). The author gives a
short analysis of this scheme, which shows, that it is
advisable to use converters with direct converting of
frequency and phase number for the feeding of point-
welding machines. Two schemes of switching with auto-
matic control for frequency converters are described
(Ref. 6). The methods are worked out by the Institute

TITLE: The Power Factor of Resistance Welding Machineliwith Ignitron
Control
PERIODICAL; Avtomaticheskaya evarka, 1960, Nr 3, PP 31-36
ABSTRACT: In determining cos 1P of single-pb%se resistance welding machines
with controlled ignitron interr4pters, or of three-phase machines
with frequency converters, the distortion of the current curve
must be taken into account, but no data on the cos V of such
machines exist in literature. The purpose of this work i9 to
fill in this gap to a certain degree. An experimental method
based on the use of equivalent circuits is suggested in order to
avoid cumbrous calculations. By employing it, the author succeeded
in determining the existing dependence of the power factor on the
ignition angle of the ignitrons in machines with ignitron control.
He also found that the welding current adjustment by changing the
ignition angle markedly decreases the power factor,. It was also

arc voltage of 24-30 v. Powerful current pulses at a frequency rate of 50 pulses
per second were superimposed on the main current. Depending on the main current,
..the pulse'amplitude and duration were varied so as to ensure transfer of one drop
of.metal with each.pulse. The use of superimposed current pulses improved weld
&Y-4mation, sharplyreduced spattering, and stabilized the arc.: Well-formed vertical
'welds were obtained at a current as low as 150 a. The weld had a fine--grained
