Plasma-arc welding

You should be able to find several indispensable facts about Plasma-arc welding in the following paragraphs. If there's at least one fact you didn't know before, imagine the difference it might make.

The more authentic information about Plasma-arc welding you know, the more likely people are to consider you a Plasma-arc welding expert. Read on for even more Plasma-arc welding facts that you can share.

Plasma-arc welding

1. In plasma-arc welding (PAW), developed in the 1960s, a concentrated plasma arc is produced and directed towards the weld area.


2. Figure shows the two types of plasma-arc welding processes: (a) transferred and (b) nontransferred. Deep and narrow welds can be made by this process at high welding speeds.


3. The high heat concentration can penetrate completely through the joint (keyhole technique) with thicknesses as much as 20 mm for some titanium and aluminum alloys.
