Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stainless steel pipe production, in particular to a welding device for stainless steel pipe production. BACKGROUND

[0002] In the modern industrial field, stainless steel pipe fittings are widely used in many key industries such as petroleum and chemical industry, municipal water supply, food processing, shipbuilding, etc. due to their excellent corrosion resistance, high strength and good plasticity. With the rapid development of these industries, the demand for stainless steel pipe fittings continues to rise, and the welding quality, production efficiency and automation level of the pipe fittings are also more stringent requirements.

[0003] In the traditional welding method, after the stainless steel pipe fitting is welded, excess metal structures such as weld beads and burrs are often generated at the weld, which can affect the appearance quality of the pipe fitting and may hinder fluid transportation, even causing health and safety hazards in specific application scenarios. The traditional post-welding processing method is to place the welded pipe fitting in the polishing position and then use tools such as an angle grinder and sandpaper to polish manually. This method not only has high labor intensity and low polishing efficiency, but also is relatively cumbersome, affecting the production efficiency. Therefore, a welding device for stainless steel pipe production is needed. SUMMARY

[0004] The purpose of the present application is to provide a welding device for stainless steel pipe production to solve the problem of the traditional post-welding processing method, which is to place the welded pipe fitting in the polishing position and then use tools such as an angle grinder and sandpaper to polish manually.
