The advantagesofthe plasma method

The advantagesofthe plasma method

Plasma welding has the following advantages, relative to those of other methods:

I. Reliable penetration with the keyhole method.

2.   Very high speed: often 400 % higher than that of conventional TIG welding.

3.   Butt welds possible in thick materials (8 mm) without the use of fillers.

4.      Fusion welding possible even in very thin materials (0.03 mm).

5.   Low weld convexity and root bead. This is particularly beneficial when welding

structures that will be subjected to fatigue loading, in addition to reducing the work

required in other welds where the weld convexity and root bead would otherwise

have to be ground away. Plasma welding of 5 mm austenitic stainless steel produces

a weld convexity of about 0.3 mm and a root bead of about 0.2 mm. Increasing the

steel thickness to 8 mm results in corresponding respective thicknesses of 0.7 mm

and 0.6 mm.

6.  Low heat-affected zone and little distortion.

7. High arc stability at low arc currents.

8.   Little sensitivity to arc length variations as a result of the concentrated arc.

9. Assessment of the weld quality possible while welding is in progress.

10. High metallurgicalquality in comparison with that of conventional TIG welded

materials.
