Classification of plasma welding methods

                     Classification of plasma welding methods 

                There are three different classes of plasma welding, depending on the current range :

Micro plasma(0.1-15 A). The concentrated arc enables it to remain stable down to a

current of about 0.1 A, which means that the process can be used for welding metal

thicknesses down to about 0.1 mm. This makes the process attractive to, for example,

the space industry. 

Medium plasma welding(15-100 A). In this range, the method competes more

directly with TIG welding. It is suitable for manual or mechanised welding and is

used in applications such as the automotive industry for welding thin sheet materials

without introducing distortion or unacceptable welded joints, as are produced by

MIG welding, or for the welding of pipes in breweries or dairies .

the joint edges in a butt weld are melted as the plasma jet cuts through them. As the

jet is moved forward, the molten metal is pressed backwards, filling up the joint

behind the jet.
