Inert gas welding requires the exclusion of oxygen from the weld zone during the welding process. The shield gas ( typically argon ) needs to be free of oxygen from air leaks into the feed hose and the back side of the weld needs to be protected with a purge, or backing, gas to ensure a low or controlled oxygen concentration on the back face of the weld. On the front face of a weld the the inert gas stream (provided it is free of leaks ) efficiently excludes oxygen from the weld zone. On the back side of the weld special precautions must be taken to prevent oxidation. This involves the isolation of the back side of the weld with fixtures that provide for the purging of this area with an inert atmosphere. The OXY-SMART instrument works with these fixtures to continuously sample the purge gas and to monitor the oxygen concentration. Monitoring the weld gases with an OXY-Smart adds a quantifiable element of quality control to the inert gas welding process.
