Welding Pipe Technology

(1)argon arc welding

Advantage: high welding quality and good penetration performance.

Appliance: Welded pipe products in the chemical industry, nuclear industry and food industry has been widely used.

Disadvantage: welding speed is not high

(2)High frequency welding

Advantage: welding high speed.

Disadvantage: It’s hard to remove burrs in the pipe. AISI 409

(3)Combined welding technology

combinatorial methods:

Argon arc welding and plasma welding; High frequency and Plasma welding ;

High frequency preheat and three torch argon arc welding;

High frequency preheat and plasma argon welding
