What is Autogenous Welding? – materialwelding

2021-11-26  Autogenous welding processes create more even weld compare to weld with filler. Improved fatigue properties: TIG refusion is usually carried out using Autogenous TIG on weld toes to increase the fatigue resistance of the welds. Reduced post weld griding job. Autogenous TIG require little grinding as not additional filler is added.
