The production of the steel plate is one of the early innovations that led to the development of the welded steel tubes. The forge welding process was among the early systems to be used. A steel plate is forged over a mandrill/folding system to form an open pipe. Heat is then applied to two open edges to the point at which they are mated together. They are then mechanically pressed together using a tool known as a draw bench.

This process has advanced continuously to the point that currently electric welding is done. Open seam pipes are formed in a continuous electric system and joined through an induction welding system. The pipe is then heat treated and cut to the required lengths. This process is then completed by an ultrasonic inspection of quality and released to the market.
