Abstract

The invention relates to a protective device for liquid protection welding and a using method thereof. The protective device is used for protecting liquid welding, comprises an inner layer protective shell, an end cover and a welding gun, the welding gun penetrates through the end cover and extends into the inner layer protective shell, and is characterized in that an outer layer protective shell is arranged outside the inner layer protective shell, the end cover is arranged at the top ends of the inner layer protection shell and the outer layer protection shell, so that a protection cavity is formed between the inner layer protection shell and the outer layer protection shell, and protection liquid is arranged in the protection cavity, which solves the problem that traditional underwater welding methods have welding equipment and method defects, welding stability and quality are poor, and the welding method can be widely applied to the technical field of welding.

Description

technical field [0001] The invention belongs to the field of welding technology, and in particular relates to a protective device for liquid shielded welding and a using method thereof. Background technique [0002] Underwater welding technology is often divided into underwater wet welding, local dry welding and dry welding according to the degree of isolation of the water environment. Among them, although the underwater dry welding can guarantee the weld quality almost equal to that of the land welding, the equipment is very complicated and the welding cycle is long, and the equipment is expensive; the underwater wet welding equipment is simple but the welding quality is relatively lower than the other two methods; Partial dry welding also realizes relatively simple equipment and procedures on the basis of guaranteed weld quality. However, in the underwater environment, especially in deep water, the stability of the structure is likely to deteriorate after the local dry we...
