When welding metals such as stainless steel, titanium and zirconium it is important that the welding zone is purged of oxygen even as low as 10 parts per million (ppm) before, during and immediately after welding, in order to achieve a clean, oxide free, zero colour weld.
Huntingdon Fusion Techniques HFT®, whose US headquarters are located in Florida, now manufactures accessories for their range of Inflatable Weld Purging Systems, which include Argon Feed Hose for a leak-tight gas connection, PurgeGate® to ensure the inflatable dams do not burst due to over-inflation and Heat Protective Covers for all sizes and temperatures.
HFT® also designed Heat Resistant Covers for both their PurgElite® and PurgExtra® Tube and Pipe Weld Purging Systems, with a temperature endurance of up to 300° C, available from 1 to 24 inches.
