Applications, advantages and disadvantages of plasma arc welding

Today I will be discussing on the applications, advantages and disadvantages of plasma arc welding. Previously, an article was published on plasma arc welding. Check out!

Applications, advantages and disadvantages of plasma arc welding

Applications

Micro-plasma welding is traditionally used for welding thin sheets at minimum of 0.1mm thickness and wire and mesh section. It is used in the marine and aerospace industries. Plasma arc welding is used to weld pipes, and tubes of stainless steel and titanium. It is a good choice when repairing tools and die. This welding process is also used for welding and coating on a turbine blade. Finally, plasma arc welding is widely used in electronic industries.

Advantages

The followings are the benefits of plasma arc welding process.

  • Ability to cut all metals
  • It allows better control of arc
  • Due to the higher heat produce and the plasma jet allows faster travel speeds
  • Heat affected zone is similar to GTAW
  • High heat concentration of plasma allows keyhole effect, which provides complete penetration with a single pass welding of many joints
  • It provides more freedom to absence and controls the weld
  • It can cut metals even faster than oxy-fuel welding
  • PAW welding is easy to automate
  • It leaves narrower kerf

Disadvantages

Despite the good advantages plasma arc welding offers, it still have some limitations. The followings are disadvantages of the welding process.

  • Plasma welding equipment are expensive
  • It requires specialize training and personnel to perform the operation
  • Higher noise is produce.
