ABSTRACT
The article discusses the applications of gas tungsten arc welding, high frequency (HF) welding and laser welding in stainless-steel tube manufacturing. HF welding has the ability to process the tube at very high speeds. Weld flaws in HF welded joints can be present as thin planar areas of low-strength bond and may not be reliable in some demanding automotive applications. Benefits of gas tungsten arc welding (GTAW) include repeatability, spatter-free welds and elimination of porosity. The laser welding process is known to be faster than GTAW with equivalent scrap rates and better metallurgical quality, resulting in higher burst strength and higher formability.
