It is vital when welding metals such as stainless steel, zirconium and titanium that the welding zone is purged of oxygen to a level as low as 100 parts per million (ppm) or even 10 ppm to ensure oxide free, zero colour welds are achieved.
Chrome steels must also be purged correctly during their heat treatment cycles before and after welding as well as during the weld purging process.
To help you understand the different weld purging techniques, we have created the following pdf's:
