Abstract

The invention relates to a high-power single inversion stud welding machine. The high-power single inversion stud welding machine comprises an EMI filtering circuit, a three-phase rectifying circuit, a parallel type high-power inverter circuit, a high-frequency transformer, a fast recovery rectifying circuit, an inversion drive circuit, a protection circuit and the like. Four bridge arms in the parallel type high-power inverter circuit are respectively composed of a plurality of inversion switching tubes connected in parallel. The output ends of secondary windings of the high-frequency transformer respectively pass a fast recovery diode to be connected together so as to be output. The high-power single inversion stud welding machine solves the high-power output problem with the working voltage in the range of three-phase AC180 V-AC600 V under one inversion system, the application range is wide, and the high-power single inversion stud welding machine has the advantages of being smaller in size and lighter in weight under the same power. In addition, the high-power single inversion stud welding machine has the advantages of being good in safety and stability, simple in manufacturing technology, low in production cost and the like and has the obvious application value.

Description

technical field [0001] The invention relates to a high-power single inverter stud welding machine, which belongs to the technical field of inverter stud welding machines. Background technique [0002] Stud welding machines are mainly divided into: capacitor energy storage type stud welding machine, drawn arc capacitor energy storage stud welding machine, and short cycle stud welding machine. The above stud welding machines can only weld Φ10mm or so welding studs on thin plates; There is also a long-cycle arc stud welding machine, which is used for Φ3mm~Φ36mm stud welding. The welding time of the long-cycle stud welding machine is 100ms to 2000ms, and some use 5000ms, and the maximum welding current is 2000A to 4000A. [0003] Long-period stud welding is mainly used in major projects such as welding shear studs (studs) for building steel structures, embedded parts for high-speed railways, large bridges, and machinery. The long-cycle arc stud welding machine has a thyristor ...
