ABSTRACT:
The welding head assembly for welding together a pair of cylindrical tubes wherein one of the tubes protrude along with a mass of other similar tubes from a tube sheet. To precisely locate the welding head position at an exact position for each and every produced weld there is utilized a locator plate assembly which is to be fixedly mounted a precise distance from the tube sheet directly on to the tube which protrudes from the tube sheet. The locator plate assembly includes a position locator mechanism which connects with the face of the tube sheet to precisely locate the locator plate assembly a precise distance from the tube sheet. A location gage assembly is to connect with the locator plate assembly to initially establish the desired position for the locator plate assembly. Upon removal of the location gage assembly from the locator plate assembly, a welding head is to be engaged with the locator plate assembly.
