Magnetically Impelled Arc Butt Welding

A pressure welding process for tubes where an arc is rotated along the joint at high speed by a magnetic field. This results in uniform heating followed by upsetting.

The magnetic field moves the electrons in the arc and ensures even heating along the joint. This makes the weld cleaner and reduces the risk of porosity. If you don't set the magnetic field or arc speed properly, you'll get uneven heat input and thus defects in the weld. Make sure cooling isn't too rapid, otherwise the structure becomes hard and crack-prone. Simply adjust the settings on the machine to the material and position, and check the weld after welding.
