Secondary rectified spot projection Welding Machine is a new type of secondary rectified Spot Welding Machine which is used for welding by adding high-power silicon diode at the output end of secondary windings of resistance welding transformer and changing alternating current into direct current.
When the output current is the same, the power factor of the spot welding machine is greatly improved, up to 0.8-0.9, and the apparent power required by this welding machine is only 1/3-1/5 of the apparent power of the ordinary welding machine, and the impact on the power grid is small.
Dc heating not only avoids the heat loss caused by cooling when the AC amplitude drops, but also prevents the splash caused by excessive peak current. The bunching effect caused by DC current flowing through strong magnetic metal makes the solder joints formed well and the penetration is strong, and the quality of multi-layer steel plate spot welding can also be guaranteed.
Can be half wave start welding, welding accuracy is high
The corresponding welding time is fast, the shortest discharge time is 10 milliseconds.
With current bunching effect: Secondary rectifier point convex welding machine output small ripple DC current, according to the welding zone has a centralizing effect like the center, it can make the welding heat concentration, the welding spot around the thermal interference area is small, DC welding current bunching effect is small resulting in welding splash, improve the electrode life, and save the electrode grinding time, greatly improve productivity.
Secondary Rectifier Spot Welding Machine also contains DC output, low inductive reactance, no alternating electromagnetic force between the two poles, and indicates the advantages of the welding machine when the electrode arm is extended, which will not cause huge inductive reactance due to the extension of the workpiece or arm extension, and the welding current is weakened, so that the electrode pressure is stable.
Three-source three-phase load stability: the three-phase secondary welder is powered by the three-phase power supply, and its operation does not interfere with the three-phase balance of the power grid.
Uses：
In addition to welding low carbon steel, coated steel, stainless steel, heat-resistant alloy, copper, aluminum and aluminum alloys, it can also weld titanium, niobium, zirconium, tantalum and other rare metals and multi-layer steel plates. Widely used in automotive, aviation, aerospace, atomic energy and radio and other industries.
Prepressing, Preheating, Cooling. Welding (Forge and Press), Cooling. Tempering. Maintaining Hold; The Heat of Preheating, welding and tempering could be adjusted respectively.
Compensation For Power Grid Voltage Fluctuation
When the value of power grid vltage fluctuates within the range of ±10 %, the secondary voltage fluctuates within the range of≤±3%
