Replace Foam Dams with a Quality Purging System

Quality Purging: Weld Purging dams are still fabricated on-site by welders to save money. They are often made from unsuitable materials such as foam, wood, paper and even tape. These types of Weld Purging dams can often leak, become displaced and even burst into flames. Rework is then consequently necessary and in some cases welds […]

Weld Purging Tube and Pipes

When welding stainless steel, zirconium or titanium tubes and pipes, the oxygen must be purged down to a level where the alloy will not oxidise since this can lead to a loss of corrosion resistance properties. This is usually under 100 ppm for stainless steel and under 50 ppm for titanium. The Pre-Purge Process Displacing […]
