At Spirax Sarco’s Engineered
Systems Manufacturing unit
in Cheltenham, Kemppi
welding equipment plays a
pivotal role in the fabrication
of bespoke steam systems and
heat exchanger systems. The
facility has a large fabrication
shop where flash steam and
blowdown vessel components
are prepared for welding.

The company has a
number of Kemppi welding
systems including two
recently delivered FastMig
Synergic water cooled
MIG/MAG welding systems
comprising KMS400 power
sources and MSF57 wire feed
units, both with WiseRoot for
root pass welding.

These two systems were
purchased to carry out root
pass welding on blow down
vessels to speed up the
operation. Previously, Spirax
Sarco was putting a root run
in using TIG welding
equipment, which was a time
consuming process. Now it
puts the root in on a 3mm
gap using 1.mm A18 MIG
wire with a mixed gas at a
much faster rate and then fills
using submerged arc welding
as before.
