flash butt welding exampleThe main advantages of Flash Butt welding is the speed and the overall strength of the process, there is no foreign weld material used meaning the product can be heat treated afterwards further increasing tensile strength.

This process is regularly used where high strength is required, typically lifting links and chains.

Capacity of 6mm – 60mm in either square or round material.

The Flash Butt Welding Process

flash butt welding process A process where the surfaces of the work pieces are positioned end to end and are then electronically charged, producing an electric arc that melts and welds the ends of the segments. Flash Butt Welding is typically divided into 3 stages:

• Preheating
• Flashing
• Upsetting

Preheating is carried out under low welding pressure. Once the welding joint is heated, flashing commences. Joint surface material is burnt off, resulting in an even surface. After arriving at preset flashing loss, upsetting commences, resulting in an irregular "fin" on the surface of the upset metal consisting of molten and oxidized material.
