Abstract

The invention is an embedded digital control inverter power source used in tube and plate overall position automatic welding, which comprises a main circuit, a control circuit and a high frequency arc-ignition circuit. The main circuit comprises a rectifying wave filter module, a high frequency inverter module, a power voltage-transforming module and a rectifying smooth module which are connected sequentially. The rectifying wave filter module is connected with a three-phase alternating current (AC) input power, and the rectifying smooth module is connected with a load. The control circuit includes an over-voltage and under-voltage protective testing module, a voltage and current sample testing and feedback module, an ARM microprocessor and a high frequency drive module. The over-voltage and under-voltage protective testing module is respectively connected with the three-phase AC input power and the ARM microprocessor. The voltage and current sample testing and feedback module is respectively connected with the ARM microprocessor and the load. The ARM microprocessor is also connected with the high frequency drive module and the high frequency arc-ignition circuit. The high frequency drive module is also connected with the high frequency inverter module, and the high frequency arc-ignition circuit is also connected with the load. The invention can realize the overall digital control of the tube and plate automatic welding inverter power source.

Description

technical field [0001] The invention relates to a welding power supply, in particular to an embedded digital control inverter power supply for all-position automatic welding of tube sheets. Background technique [0002] In recent years, in order to meet the demand for electricity, all parts of the country have stepped up to build new power plants and increase the capacity of power plants. In the power construction industry, the manufacture of medium and large condensers / heat exchangers is particularly important. The connection of tube head tube plate joint is a key process in the whole condenser / heat exchanger manufacturing process. The number of such welded joints is large, the distance between welding positions is small, and the nozzle joints have been subjected to the axial load generated by the pressure difference for a long time, repeated heating, cooling, high pressure and medium corrosion fatigue strength damage, and the compactness of the weld. The performance and m...
