(Pribordlya izmereniya vremennykh evarochnykh deformatsiy)
PERIODICAL::. Svarochnoye proizvodstva, 1959, Nr 3, PP 16-18 (USSR)
ABSTRACT. This deformation-meter'"DRV-211 is'designed for the experimen-
tal determination of the deformations taking place during
the welding proceset and the subsequent cooling of metal
frame structures.. The instrument is.of indicator type design
and measures the crosswise deformations of a joint. It can
also measure thelengthwise deformations in slightly heated
. .areas in a welded.joint. Detailed design information is
given and the computations to be made are illustrated by
examples. The measurement errors.caused by the design fea-
tures do not exceed 0.06 4, and can be increased up to 0.25 %
Py an inaccurate betting.

meter for automatically indicating and recording welding

carrying four, wirestrain gauges, two on the inside diameteri

strain of the ring.. The',strain gauges are of constantan wire
'0.030 mm diameter and each has a resistance of 250 ohms, forming a,,
four-ar.m bridge. , Supply is.from a six-volt accumulator and
readings are by millivoltmeter. It is shown that there is a

TEM, -Investigated are the internal deformations, acting inA perpondiou-
lar direction to the seam,.to which the butt weld is subjected in the process of
metal crystallization during the automatic single-pass Relding of a low-carbon
steel. The development of such deformations is,one of the causes leading to the
formation of hot longitudinal*cracks in welds. The following concluoiona are
drawn: (1) During the slngle-pass welding, whenth.e cooling metal in in~a tempera-
ture range of brittleness, the transverse free temperature deformation will be close
".,to-zero. (2) The transverse deformations (the actual ones) arising during the
process of the actual'butt-joint welding are not generally constrained. They may
change within a wide ranges-depending on the concrete combination of constructional

TEXI!: Results are given'of the experimental determination of shrinkage

Kiyev Polytechnic Institute. A simulation system of hindered shrinkage and'
typical cases,of the development of stresses,in natural weld joints were applied.

which is thb basis of existing concepts on the deformation of the weld metal
during-crystallization.-is not in agreement with the experimental data obtained.
This process cannot be used to explain tensile stresses developing at a high
rate and low rigidity of the weld joint, or compressive stresses in the crystal-
lizing weld, The.experimental data show that stresses of the solidifying weld
