meters high, and had a top consisting of rollers and four curve sections of
channel steel, two on each side, securely welded to it between which the rolled
section was placed. The abutting edges of the sections were clamped together
and then clectro-argon welded lengthwise with the use of a powdery flux. Be-
neath the table was a metal container to collect the excess flux. As the
sections were welded, they were rolled out of the jig and lifted off the table
by one man and placed on the floor. When the required number of sections were
prepared in this manner, they were placed together on a similar type table-jib
and welded together by the same method. The pipe with the discs was inserted
and the ends of the tank were then electro-argon welded. The tank was then
lifted by crane onto a flatbed carrier drawn by an elsetro-car and the unit was

The connecting;; pipe group was identified as the first gyroup. This pup
emaloye3d approximately 50 workers in a ratio of about i5, 10 and 5 Der first,
50X1-HUM
In general they prepared
eonnec pipes associated related to the combustion chambers.
These connecting pipes were made of an unknown type of aluminum alloy
estimated to be about two to three mi113aaaeters thick. The material for
these pipes was prepared in Shop !o. 17 where the pipe was cut to approximate
also and then steed (pressed) to shape. The shaped material was then
sent to this group where it underwent the final work processes. This
included the preparation of the pipe for soldering;, i.e. beveling the
edges to be soldered, soldering by the use of an electric oven and a
brass (latun) solder composed of sine and copper, polishing and grinding,
and anodizing. The item underwent the usual pro-stage inspections per.. 50X1-HUM
formed by resider sho ins sectors as opposed to military inspectors. 50X1-HUM
inspection marks or staffs were used during,
the intermediate work phases but when completed, an unknown inspection mart
was etched on an unknown part of the pipe with an acid solution. When the
item was completed, it was sent to the central warehouse (Ts G G D -
tsentralqyy ,sklaci g;;otovykh detalov) rather than to another shop for immediate
use. From this warehouse, the parts were sent to the engine assembly
shop or to another pre-aaae=Uly shop as required. 50X1-HUM

7. The casing unit for the combustion chamber was n in its entirety in this
group. It was made of an unknown high -rode steel alloy received at the
plant from the Serp i Molot Steel plant in scow. The shop received the
steel in sheet form about two meters square and one and one-half to two
millimetcra thick.
8. The combustion units were laved out in the shop and by use of a pattern
were then cut out. The a es to be soldered were beveled and then the
cut-out material was subjected to a cold welding operation to obtain the
desired fors. Gctly one rolling; operation was necessary. The unit was
spot-welded in two or three places and then the entire seam was soldered
with the brass solder mentioned above. This soldering operation was per-
formed in a special electric oven designed and built at the plant in Shop
No. 12 specifically for this phases of worst. This was a large oven
approidmately 10-12 meters long which stood about a meter and a half hi
and was about a meter wide. (Rotor to peace 10 sketch
of the oven.) The inside of the oven contained a conveyor on which
the casing units were placed and moved from one and of the oven to the
other. At the removing end of the oven there was a cooling chamber in which
the casing, nnits were sprayed with water.
9?
In soldering the seas of the housing unit, a lent; of the brass solder wire
was placed in the previously prcpared beveled groove. The unit was then
placed upright on the conveyor in the oven and the heat therein fused the
solder to the steel unit. The unit was in the oven for about lo minutes
and the operating temperature was about 9,50 de Tees centiErde. The oven
was constructed in such a manger that when the outer door of the cooling;
chamber was opened, a door slid down and closed on the oven from the
coolin chamber to prevent any loss of heat. The ccxal.iru; process was
about five minutes long and upon completion, the casing unit was withdrawn
and set aside. Ultiz tely, the unit was cleanesd, (flakes were chipped off)
and then it was fitted with an .,le iron fianaces on the upper and lower
portions. Moo* flanjes, previously rolled into shape in the flan shop,
had an unknown number of bolt holes drilled through one lip of the flange.
The drilling operation was performed by this work group. The flan ,,u was
then fitted around the outside circumference of the housing; unit and
electrically welded. Both ends of the housing, unit were secured for
testing purposes only, and the unit was submerged in water and subjected
to a hydraulic pressure test at tour atmospheres. Upon successful completion
of this test, the unit was dried, inspected and than sent to an unknown
shop to be painted (presumably are=). From the paint shop, the unit
was sent to the central warehouse (Ts a G D) to be used as required.
