Those who have seen the thick wall pipe welding machine will basically pay attention to the welding process to see how it is welded. They are also very interested in the welding machine. Many supporting welding machines of the thick wall pipe welding machine are plasma welding machines. Why? Can't the conventional argon arc welding machine work? In fact, it depends on the specific situation of the enterprise.

Firstly, the thick wall produced should be compared. Generally, if the thickness reaches 3.0 thickness, plasma welding machine will be selected, but this is not absolute. This thickness can still be solved by reinforced argon arc welding machine. If it reaches more than 5.0 thickness, it is not necessarily. The power and penetration of many argon arc welding machines can not meet the use requirements, At this time, a plasma welder with strong penetration is needed.

The other is the thick wall pipe welding machine. Even if the plasma welder is selected, it still needs to be equipped with more than two welding guns, at least two, because if only one plasma gun is used, even if the pipe is fully welded, the surface of the pipe is not smooth, so an argon arc welding gun needs to be added for sweeping.

Now can you understand why you choose plasma welder for thick wall pipe welding machine? In the next article, we will continue to discuss the welding methods of thick wall pipes.
