Abstract

The invention provides an automatic flat welding device capable of shooting underwater arc and simulating different water depths. The rack of the device is arranged in a welding pressure cabin, and a sliding track and a sliding guide wheel which are meshed with each other are arranged on the rack and allow the rack to go in or out of the welding pressure cabin in parallel; a vertical welding rod / welding gun feeding mechanism is fixedly arranged at the top of the rack through a bolt, and a welding rod / welding gun clamp is fixedly arranged on a movement sliding block of the vertical welding rod / welding gun feeding mechanism; a horizontal two-dimensional motion x-direction platform and a horizontal two-dimensional motion y-direction platform are sequentially arranged at the bottom of the rack, and a water tank is arranged on the horizontal two-dimensional motion x-direction platform. The automatic flat welding device has the beneficial effects that the droplet transfer, arc states and the melting bath behavior in the underwater welding process are shot at high speed, the underwater wet welding and local dry welding can be simulated, and the hyperbaric dry welding can also be simulated. The maximum design pressure of the welding pressure cabin is 3Mpa, and the 300m-water-depth underwater wet welding, local dry welding and hyperbaric dry welding is realized.

Description

technical field [0001] The invention relates to underwater welding equipment, in particular to an automatic flat welding device capable of photographing underwater arcs and simulating different water depths. Background technique [0002] In order to meet the needs of human beings for resources, the exploitation of marine resources will become more and more intensive, and the structures that exploit resources on the ocean will gradually increase. However, it is impossible for all marine structures to be used all the time. Bear the working load, but also resist various additional loads in the seawater environment. Under such conditions, welded structures are prone to fatigue failure, brittle fracture or stress corrosion cracking. In order to maintain and repair marine structures, underwater welding technology is becoming more and more important, and has attracted the attention of many welding workers at home and abroad. At the same time, the workload and technical requiremen...
