A, Welding power and frequency determination:

In order to achieve the same welding speed, copper tube requires maximum power, the highest frequency, followed by stainless steel, steel, aluminum.

1, The required welding power calculation as followes:

Pout = K1xK2xdxbxV (kw)

The parameters explaination as following:

Pout: welding power (kw);

d: pipe wall thickness (mm);

b: heating width (in extreme condition, generally assumed as b=1cm);

v: welding speed (m / min);

K1: pipe material factor;

K2: tube size factor.
