SAW Pipes
& SAW Tubes: This process is used
for pipes from 24" to 36" i.e 610mm to 914mm
OD. Flat plate is first pressed into U and
later O shape. The O shape is placed in an
automatic welder and backed up on the inside
by a water cooled copper shoe. Two
electrodes in close proximity and used. The
electrodes are not in actual contact with
the pipe. The current passes from on
electrode through a granular flux and across
the gap in the pipe to the second electrode.
The high temperature of the arc heats the
edges of the plate, a welding rod placed
just over the seam is thereby melted and
metal is deposited in the groove. After the
outside weld has been made, the pipe is
conveyed to an inside welder where a similar
operation is carried on, except that no
backup shoe is need.
