- Abstract
In order to realize underwater automatic welding in deep water environment, an automatic welding equipment, which is composed of truss structure, welding mechanism and mobile walking mechanism was designed and tested in the recent research. The bent fatigue strength check was carried on the driving part of the system. High-pressure chamber was used to simulate the high pressure deep water environment. Test of the automatic welding equipment test was conducted by the flux core arc welding(FCAW) in pressure chamber under hydrostatic pressure about 30-200 meters of water depth. Arc voltage and welding current were recorded during the welding tests. Visual inspection was also conducted on the weld. According to the above tests results, it was shown that the automatic welding equipment works stably and credibly, and the apperance of weld was excellence. It was concluded that this equipment can satisfy the requirements of underwater automatic welding in high-pressure underwater environment.
