Automatic Girth Welder

Automatic Girth Welder


Main Parts


WUXI ABK provides submerged arc welding machine used for vertical cylinder construction. Different from the current market, our MSHW series automatic girth welder is equipped with a stable dual drive system. The self-propelled submerged arc welding system can help reduce the constructions time to 25% of the manual welding. The transverse welding machine is used for welding the inner and outer ring of the vertical cylinder. We offer automatic girth welders with 3 configurations for various types of tanks.

A. Operator Platform

Description Its main frame is composed of transverse welding operation unit and welded steel structure.
Applicable for “bottom up” tank erection
Min. dia.: 5.0m
Shell plate : 1.5m~2.5m

B. Dual Drive Unit
AC double drive design allows this submerged arc welding machine to make a full circle around the tank and weld all the defects and flaws while it’s moving. This dual drive system is more stable and easier to use compared to single drive system, and it’s more efficient in repairing defects.
  • Programmable variable frequency drive
C. Power Source and Wire Feeder
Description The welding system is equipped with LINCOLN NA-3 control and wire feeder, as well as the corresponding wire spool and wire reels. It accommodates coils of submerged arc welding wires below 27.2kg.
