Electric-Resistance-Welded Pipe—Pipe produced in single lengths, or in multiple lengths from coiled skelp and subsequently cut into individual lengths, having a longitudinal butt joint wherein coalescence is produced by the heat obtained from resistance of the pipe to the flow of electric current in a circuit of which the pipe is a part, and by the
application of pressure.
