What are the seamless steel pipe welding methods

Seamless steel pipes may need to be welded during manufacture, installation and use. The following is a list of several seamless steel pipe welding methods:

Pipe-to-pipe welding: welding is carried out after the ends of two seamless steel pipes are aligned, including manual arc welding, gas shielded arc welding and submerged arc welding.

Pipe-to-flange welding: it is to weld seamless steel pipe and flange after butt joint, which is a common connection method in pipeline system, including manual arc welding, gas shielded arc welding and submerged arc welding.

Pipe end-to-pipe side corner welding: it is to align the pipe ends and weld on the pipe side. Manual arc welding or TIG welding methods are usually used. It is suitable for small production and low demand occasions with low cost.

Pipe end-to-pipe end angle welding: it is to align the pipe ends and weld the pipe ends. Automatic welding robots or TIG welding methods are usually used. It is suitable for mass production, high demand and high safety requirements.

In general, there are many different welding methods for different application fields and specific requirements of seamless steel pipes. Choosing a suitable welding method can improve the welding quality and ensure the safety and effect of seamless steel pipe.
