Electric Resistance Welding (ERW) Process

Pipe is created using the Electric Resistance Welding (ERW) process by cold-forming a flat steel sheet into a cylindrical shape. The steel is then heated to a degree at which the edges of the steel cylinder are pressed together to establish a bond without the use of welding filler material.
Several Electric Resistance Welding (ERW) processes are available for pipe production. The two main types of ERW are:
. High Frequency Welding
. Rotary Contact Wheel Welding.

High Frequency Welding

In high frequency induction welding, a work coil is placed in front of the weld spot and acts as a conduit for the weld current to reach the material. Work coil does not come into contact with pipe. Through the magnetic fields that surround the pipe, an electrical current is induced into the pipe's substance. When changing pipe size, high frequency induction welding avoids contact marks and requires less setup time.

Rotary Contact Wheel Welding

The electrical current is passed through a contact wheel at the weld spot in rotary contact wheel welding. A portion of the forge pressure required for the welding process is also applied by the contact wheel. AC, DC, and square wave are the three primary types of rotary contact wheel welders. Electrical current is transferred in all three power supplies by brush assemblies that interact with slip rings attached to a revolving shaft that holds the contact wheels. The current is sent to the strip edges through these contact wheels.

Submerged Arc Welding (SAW) Process

A constantly fed bare wire electrode and the workpiece form an arc during the submerged arc welding (SAW) process. To produce protective gases, slag, and to add alloying components to the weld pool, the procedure requires a flux. Using a shielding gas is not necessary. Excess flux is recycled via a hopper as the arc advances along the joint line. After welding, any remaining layers of fused slag are simple to remove. The arc is generally invisible during welding because the flux layer totally covers it, and heat loss is also very minimal. In contrast to the manual metal arc's 25% thermal efficiency, this one can reach 60%.
There are two types of Submerged Arc Welding (SAW) processes:
. Longitudinal Submerged Arc Welding (LSAW) Process
. Spiral Submerged Arc Welding (SSAW) Process
