Abstract

The invention discloses a split type multifunctional underwater arc welding power supply which comprises 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 arranged on the shore; and the underwater power supply module is carried underwater. An integrated arc welding power supply directly arranged on the shore in the prior art is designed in a split mode, and real-time adjustment of the welding state during underwater welding can be achieved.

Description

technical field [0001] The invention relates to the technical field of underwater arc welding machines, in particular to a split-type multifunctional underwater arc welding power supply and a working method thereof. Background technique [0002] In the 21st century, mankind's demand for energy is becoming more and more urgent, and the development of marine resources has gradually become one of the important ways for human beings to obtain energy. With the increasing service time of important marine structures such as offshore oil platforms and various submarine pipelines, the underwater important structures of a large number of offshore engineering facilities have gradually suffered some damage that must be repaired in time. Therefore, the connection of underwater steel structures in offshore related projects and the repair of in-service steel structures are inseparable from underwater welding technology, and the development of high-quality and efficient underwater arc weldi...
