How is heat generated in ERW pipe welding?
During ERW pipe welding, heat is generated when current flows through the contact surface of the welding area. It heats the two edges of the steel to the point where one edge can form a bond. At the same time, under the action of the combined pressure, the edges of the tube blank melt and squeeze together.See all results for this questionHome - Calcutta Steel TubeERW Pipes & GI Pipes ERW (Electrical Resistance Welding) pipes are manufactured by cold forming of steel coil into a round cylindrical shape.
