摘要：
The weld metal oxygen content can be significantly changed by a slight difference in the oxygen concentrations in the shielding gas in gas tungsten are (GTA) welding process. The effects of the welding parameters on the weld shape and depth/width ratio depend to a large extent on the weld metal oxygen content and Marangoni convection patterns.
