plasmapaarihitsaus

Plasmapaarihitsaus is a welding process that utilizes a plasma arc to join metals. In this method, an electric arc is generated between a tungsten electrode and a constricting nozzle, creating a plasma stream. This plasma, a superheated ionized gas, is then directed towards the workpiece. The high temperature of the plasma melts the base metals, and a filler material can be added to create a stronger bond.

The key characteristic of plasmapaarihitsaus is the constricted plasma arc, which allows for higher energy density compared to other arc welding processes. This focused energy results in a deep and narrow weld penetration, leading to strong and high-quality welds. The process is known for its stability, precise control, and ability to weld a wide range of metals, including stainless steel, aluminum, and exotic alloys.

Plasmapaarihitsaus can be performed in various modes, such as keyhole welding and non-keyhole welding. Keyhole welding, where the plasma melts through the entire thickness of the material, is used for thinner sections and provides full penetration. Non-keyhole welding is used for thicker materials or when a shallower penetration is desired. The process is often automated, making it suitable for high-volume production. Its advantages include high welding speed, low distortion, and excellent weld appearance.
