Girth Welder also know as 3 O'Clock Welder and Automatic Girth Welder
The AGW is a self-propelled frame designed to apply efficient horizontal seam welds by means of the Submerge Arc Welding (SAW) Process. The AGW rides along the upper edge of a large diameter filed storage tank while applying inside and/or outside welding. Compared with conventional technique, the AGW reduces the contstruction rate 25 times and cuts welding time 2.
