Butt / Flash Butt Welding Machine
Flash Butt Weld / Butt Weld is a resistance welding that does not require overlap of weld material. It is commonly used to join same or different cross section in tube, bar, rod, sheet or plates. Butt weld is also called Upset weld. Heat for welding is the resistance to electric current created through contacts between the moveable part and the fixed part. As the weld part touches, the material starts to flash and sparks (metal loses) from the weld area. The flashing process heat up the cross section of the weld part, then comes the butt weld (Upset) process. Upset process is to accelerate the movable part towards the fixed part with higher current. Rapid speed and continuous pressure will weld two pieces together. Check out our flash butt welding machine and butt welding machine below.
