Abstract
The parallel faces of thick-walled structures to be joined by arc welding are provided an electrically conductive metallic support along and up into the bottom of a gap between the parallel walls for the initial pass of the arc. The metallic support is subsequently gouged from the gap and the union of the parallel faces is completed by filling the gouged space with welding material.
Claims1
An arc welding process for joining the walls of two bodies, including,
- forming a vertical gap between the walls of the bodies to be joined,
- positioning an elongated metallic structure along the length of the gap and up into the bottom of the gap,
- tack welding the elongated metallic structure into place,
- supporting and sealing the lower surface of the elongated structure with a support body positioned on the lower face of the elongated structure,
- arc welding between the two walls forming the gap above the elongated structure and its support body until the gap is filled,
- and gouging the elongated structure from the gap and completing the union between the two bodies by filling the gouged space of the gap with welding material.
