PurgeNet™ Dew Point Purging Gas Moisture Sensor™

The presence of moisture on the joint surface can create porosity in the weld metal. It is therefore important that the dew point is monitored so that welders are made aware when moisture is likely to be present. Water can form as moisture on metal surfaces while welding and it is important to be able […]

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 […]
