Title:
SPLIT-TYPE MULTIFUNCTIONAL UNDERWATER ARC WELDING POWER SUPPLY AND WORKING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/253317
Kind Code:
A1
Abstract:
Disclosed in the present invention is a split-type multifunctional underwater arc welding power supply, comprising: a shore power supply module and an underwater power supply module. The shore power supply module comprises a shore power supply main circuit unit and a shore power supply control unit; the shore power supply main circuit unit comprises an input filter circuit, an IGBT full-bridge inverter circuit, an intermediate frequency transformer, and an output rectification filter circuit; the underwater power supply module comprises an underwater power supply main circuit unit and an underwater power supply control unit; the shore power supply module is provided on the shore; and the underwater power supply module is carried underwater. According to the present invention, an integrated arc welding power supply directly arranged on the shore in the prior art is designed in a split mode, such that real-time adjustment of the welding state during underwater welding can be achieved.
