How AC spot welding practices |
DTZ series spot welding rectifier transformer secondary winding is in the solder to join high-power output of silicon diodes, the alternating current into direct current welding machine for welding the new. Secondary to the DC circuit, the inductance can be ignored.
System modeling and simulation as well as high-power solid-state laser processing system can return to the main power pressure washer and applications: 2KW or more industrial high-power solid-state laser voltage: 380V three-phase inverter spot welder return 20kHz welding features welding machine, three spot welding rectifier with secondary main features: as well as laser spot welding.
When the same output current, the welding power factor greatly improved up to 0.8-0.9; apparent power required for this welding machine welder only ordinary 1/3-1/5 apparent power, small impact on the grid. DC heating, both to avoid the AC amplitude decreases heat loss caused by cooling, but also to prevent excessive peak current generated by splash, DC current generated by the strong magnetic metal cluster effect of forming a good solder joints, penetration , when the multi-layer steel welding quality can be guaranteed. Without a cross-arm poles magnetic transformer, electrode pressure more stable. Wide range of uses, in addition to welding mild steel, coated steel, stainless steel, heat-resistant alloys, copper, aluminum and aluminum alloy, but also can be welded titanium, niobium, zirconium, tantalum and other rare metals and multi-layer steel.
