a weld technique on diagonal cut strips of steel, superior to the butt weld process for joining flat strips of metal together before rolling into coiled tubing.

a welded connection using two pipe ends, cut straight across and welded together with minimum circumferential contact.

n: a method of flash butt welding used to weld the wide and thin or irregular weldments

n: 1. a form of resistance butt welding used to weld wide, thick members or members with irregular faces together, and tubing to tubing. 2. in pipeline construction, a welding technique in which low voltage is applied to each pipe joint while the ends are in light contact. This contact produces a rapid arcing, called flashing. After the pipe ends have been adequately heated, the current is abruptly increased, and die pipe joints are brought together rapidly and forcefully. The current is then reduced, excess flash material in the pipe is cleared. and the weld is completed.
