WINCOO Engineering offers the Automatic Girth Welder for tank fabrication applications.Unlike current girth welders on the market,the MSHW series comes standard with a Dual Drive System.This self-propelled submerged arc welding system can reduce field storage tank welding time up to 40%.Weld defects are greatly reduced,saving tank erection costs.The Girth Welder is applicable for top down or bottom up construction single or double wall storage tanks for inside and outside welding.There are four standard units,however our design allows us to offer custom built units for non-standard application.
