Description

Technical Field

[0001] This utility model belongs to the field of pipe welding technology, and in particular relates to a fixing clamp for welding steel butt-welding pipe fittings. Background Technology

[0002] In the welding process of steel butt-welded pipe fittings, fixing clamps are important tools to ensure welding quality and efficiency. Traditional fixing clamps can meet the basic requirements of pipe fitting welding to a certain extent. Through simple fixing methods, they fix the pipe fittings in a certain position and provide basic support for the welding operation, playing a certain role in pipe fitting welding production in the past.

[0003] However, existing steel butt-welding pipe fittings have many shortcomings. On the one hand, the height and horizontal position are inconvenient to adjust, mostly requiring complex manual operations, and the adjustment accuracy is limited, making it difficult to quickly and accurately adapt to the welding needs of different specifications of pipe fittings, affecting welding efficiency and quality. On the other hand, the fixing method of the pipe fittings is not flexible and stable enough, making it difficult to fix and connect two pipe fittings separately and accurately, often requiring a lot of manual assistance, which increases production costs.

[0004] To address these issues, we provide a fixing fixture for welding steel butt-welded pipe fittings. Utility Model Content
