What are the main properties of the bend pressure-balanced corrugated compensator?

The general choice of three-electrode torch argon arc welding, bend pressure balance corrugated compensator wall thickness S ≥ 2mm, welding speed than a single torch forward 3-4 times, welding quality has also been improved. Argon arc welding and plasma welding combination to be able to weld larger wall thickness of steel pipe, in addition, 5-10% hydrogen in argon gas, and then the use of high-frequency pulse welding power source, can also advance the welding speed. High-frequency welding has a higher power source power, for different raw materials, outside diameter wall thickness of the steel pipe can reach a higher welding speed.
 
Compared with argon arc welding, is its welding speed of more than 10 times. Thus, the production of stainless steel pipe for general use has a high production rate. From the viewpoint of welding materials, high-frequency welding can weld various types of austenitic stainless steel pipe. Together, the development of new steel grades and the advancement of forming welding methods, but also successfully welded ferritic stainless steel AISI409 and other steel grades. Elbow pressure balance corrugated compensator of various welding methods have their own strengths and weaknesses.
 
How to complement the strengths and weaknesses of several welding methods to be combined to form a new welding process, to meet the requirements of the bend pressure balance corrugated compensator quality and production power, is the new trend of the bend pressure balance corrugated compensator skills. Commonly used to weld non-ferrous metals, stainless steel, ultra-high strength steel and other materials. However, TIG welding shallow depth of melt (≤ 3mm), low welding power shortcomings, on the bend pressure balance corrugated compensator needs to open the bevel for multi-pass welding.
On the 8mm bend pressure balance corrugated compensator welding can not open the bevel once to obtain a larger depth of fusion or a weld through, on the bend pressure balance corrugated compensator can reduce the welding heat input without changing the welding speed. Now the bend pressure-balanced corrugated compensator can be used to weld stainless steel, carbon steel, nickel-based alloys and titanium alloys and other materials. Compared with the traditional TIG welding, bend pressure balanced corrugated compensator, can greatly advance the production rate, reduce production costs, together with the ability to reduce welding deformation, has a very important application prospects.
