Welding Programs
A precisely controlled short-circuit metal transfer that provides a calm, stable arc
and weld puddle. This provides less chance of cold lap or lack of fusion, less
spatter and a higher quality root pass on pipe. The stability of the weld process
lessens the puddle manipulation required by the welder and is more tolerant to
hi-lo conditions, reducing training requirements. Weld bead profiles are thicker
than conventional root pass welds which can eliminate the need for a hot pass,
improving weld productivity. In some stainless steel applications, it may be
possible to eliminate the backing (purge) gas to further improve productivity
and reduce welding costs.
Ideally suited to root pass welding
Consistent side wall fusion
Less weld spatter
Tolerant to hi-lo fit-up conditions
More tolerant of tip to work distance
Less welder training time
Thicker root passes can eliminate hot pass
Eliminate backing gas on some stainless steel applications
Ideally suited to fill and cap
pass welding
Easier puddle control than
conventional spray pulse
Shorter arc lengths and narrow arc
cone for out-of-position welding
More tolerant of tip to work variation
Improve fusion and fill at toe of weld
Less heat input reduces interpass cooling time and improves
weld cycle time
Enables one-wire with one-gas weld procedures
Pro-Pulse
™
This method of pulse welding provides a shorter arc length, narrower arc cone
and less heat input than with traditional spray pulse transfer. Since the process
is synergic, arc wandering and variations in tip-to-work distances are virtually
eliminated. This provides easier puddle control for both in-position and out-of
position welding, reducing welder training time. The process also improves fusion
and fill at the toe of the weld, permitting higher travel speeds and higher deposition.
This process coupled with RMD Pro for root pass welding permits welding
procedures with one wire and one gas to eliminate process switch-over time.
