High Frequency Resistance Welder

The machine is used for a special type of resistance welding process called high frequency resistance welding. This type of welding is suitable for making pipe, tubing and structural shapes. It is also ideal for joining items made from continuous strips of materials and is widely used in manufacturing industries.

Welding Process
The welding process causes fusion of metals by the heat produced due to resistance of a work piece to an alternating current of high frequency. The heat produced is also the result of continuous and fast application of a force after the completion of heating process. The contact effect controls the path of the current in the workpiece. The high frequency alternating current is introduced through sliding contacts at the edge of the joint. The current is introduced into the metal before the workpieces to be welded come in contact with each other.

Uses & Applications
There are many different applications of the high frequency resistance equipment. Some of its common application include:

• Welding steel alloys
• Welding copper & aluminium tubing
• Welding structural shapes
• Brass welding
• Metal tube welding
• Water & fuel pipeline welding
• Exhaust pipe joining
