Thin Wall Stainless Steel Pipe Combined Welding Of Argon Arc And Electric Arc

The combined welding of argon arc and electric arc is used at the bottom of seam welding for argon arc welding, electric arc welding on the surface of the cover again welding method, welding when the first ring of pipes to designate each welding butt weld area Angle and position, to determine the parameters for the districts: preheat temperature, welding temperature, current, welding, argon gas flow rate of the pulse, it combines the advantages of the two kinds of welding methods and can ensure engineering quality.

 

This construction method is mainly suitable for welding high-quality thin-wall stainless steel industry, boiler pipe installation, welding pipe diameter DN100mm~DN230mm, pipe wall thickness 3~6mm

 

Thin-wall stainless steel pipe is a new type of energy saving and environmental protection pipe, with good corrosion resistance, long service life, reliable connection of pipe fittings and moderate price. Argon welding is widely used in high pressure stainless steel pipes with high cleanliness and high engineering quality. With the development of national economy, argon welding of thin-wall stainless steel pipe will be a new trend of industrial and boiler pipe system installation.

 

Thin wall stainless steel pipe connection using combined welding of argon arc and electric arc has the following advantages compared with manual arc welding and argon arc welding technology:

 

1.1 Good welding quality

 

According to the welding process evaluation, selecting suitable welding wire, tungsten electrode, welding process parameters and protective gas whose purity meets the requirements can make the weld root get good fusion, and the qualified rate is obviously high when radiographic flaw detection is carried out.

 

1.2 high efficiency

 

When the same welder uses argon welding process and manual arc welding process to weld the same joint, the welding efficiency of argon welding process is 2-4 times that of manual arc welding, and 1-2 times that of argon arc welding, and the construction period is obviously shortened.


 

1.3 the cost is low

Through comprehensive measurement, it is found that compared with manual arc welding, argon welding can reduce the comprehensive cost of construction by 10 ~ 20%, compared with argon arc welding can reduce the comprehensive cost of construction by 5 ~ 15%, and the welding joint shape is good, low repair rate, reduce the comprehensive cost.
