Description

Technical Field

[0001] The utility model relates to the technical field of welding auxiliary equipment, in particular to a welding splash-proof device for shipbuilding. Background Technique

[0002] A ship is a general term for various vessels. A ship is a means of transportation that can sail or berth in water areas for transportation or operation. It has different technical performances, equipment, and structural forms according to different usage requirements. A ship is a man-made means of transportation mainly operating in geographical waters. An LNG ship is a type of ship, which has the characteristics of complex equipment, high technical requirements, and high cost. During the process of shipbuilding, the pipeline system is an important part, and the basic composition of the pipeline system is the connection between various pipe fittings. Generally, pipe fittings are of fixed length. When extension is required, a welding device is needed to weld two pipe fittings together for use.

[0003] When pipe fittings are welded, flying metal particles and slag will be generated. If these metal particles and slag are not blocked, they will splash onto the worker's body, causing harm such as burns. Currently, generally, a worker holds a face mask by hand to block the welding spatter from falling on the worker's face. Although this can protect the worker's face and eyes, it cannot protect other skin of the human body, and it will still cause certain harm to the human body. Moreover, the welding spatter scatters everywhere, which is likely to bring fire hazards, and the cleaning of the spatter is also quite troublesome, which is not conducive to the welding processing of pipe fittings in shipbuilding.
