Why Purge?
When welding stainless steel, titanium and other corrosion resistant materials, the perfect environment for welding is paramount to maintaining the corrosion resistant properties.
During the welding process, the weld seam is subjected to heat and air which causes oxidation, if the correct processes are not adhered to.
For the best results, oxidation must be prevented.
The quality of the exotic corrosion resistant material welding is dependent on the correct purging methods to minimise or eliminate oxidation.
Weld Quality
The effective welding of stainless steel, titanium and other exotic materials for the nuclear, petrochemical, pharmaceutical, semi-conductor, aerospace and food industries requires the proper tools to create a perfect weld environment.
Purging equipment and its use has a major impact on preventing oxidation and improving final weld quality.
The basic principles of purging can be seen below.
PPM supply a comprehensive range of systems to create the correct welding environment, whatever the application.
