What is the welding machine ?
Welding machine is a kind of heat processing equipment which converts electric energy into welding energy, so that the welding part of metal or non metal workpiece is fused or plastic extruded to reach the union of atoms. Because the welding objects are mainly made by the steel, the development of electric welder generally depends on the increase of steel output. More than half of the steel produced worldwide needs to be welded before it can be applied in practice.
As the basic processing equipment, electric welder is widely used in various sectors of the national economy. For example, producing a ten thousand ton wheel to weld up to 150km welding seam; a jet aircraft, to weld (20-30) X 104 solder joints; a 12.5 x 104 kW steel furnace, to weld a 17km long weld and 15 x 104 pipe joints; a car to weld more than 10000 solder joints and dozens of meters long weld.
