Autogenous orbital GTAW of large, high-purity tubes

July 15, 2010 | By Barbara K. Henon, Y.K. Tan

Autogenous orbital welding on large projects has become nearly routine with large numbers of successful welds completed with very low reject rates. Thus it is very easy to become complacent. However, installers need to be alert to potential problems and take immediate action when a problem occurs.

Specifying the sulfur content of 316L stainless steel for orbital welding

March 27, 2003 | By Barbara K. Henon

The widespread use of autogenous (fusion) orbital gas tungsten arc welding (GTAW) in the high-purity semiconductor and biopharmaceutical industries, combined with modern steel refining technology, has made it both desirable and practical to supply type 316L stainless steel with a restricted range of elemental sulfur.
