Figure 1 illustrates a method of welding a fill port flange to a tank. A thick circular ring 1 includes an "0" ring groove 2 for sealing and a pattern of tapped holes for securing a bolted cover. This flange must be welded to the extruded opening in the shell of the tank. The procedure used required two welds, an inside weld 3 and an outside weld 4.
