Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel pipe welding, and concretely relates to a steel pipe convenient for welding alignment. BACKGROUND

[0002] Steel pipe welding is a processing technology that connects two or more steel pipes together. Through heating, pressurization or both, and using filler material (which can also not be used, depending on the welding method), the connecting part of the steel pipe reaches atomic bonding, forming a continuous, certain strength and sealing integrity structure. This process involves the melting and solidification of metal materials, thereby achieving permanent connection between steel pipes to meet the application needs of various industries, construction, energy and other fields.

[0003] During the welding process of the steel pipe, the end part may be uneven, or the fixture may not be fixed firmly, causing the steel pipe to move during alignment, thereby causing uneven butt joint gap. In addition, changes in environmental temperature may also affect the size of the steel pipe, thereby causing the gap to change and causing misalignment.

[0004] Therefore, we improve it and propose a steel pipe convenient for welding alignment. UTILITY MODEL CONTENT
