TIG welding method is generally used for welding stainless steel and aluminum alloys. It is preferred for the welding of thin sheets due to its low heat input. The fact that the TIG torch does not deviate from the surface to be welded and the arc stability are extremely important factors for welding quality. For this reason, the use of fixtures is an important equipment for TIG welding work. In this study, a multivariable portable and fixed fixture is designed. There are suggestions for fixing the samples to be combined, minimizing the vibration problem and solutions based on heat input. The designed fixture has an adaptable for at least two-axis machines. Sheets of different lengths and widths can be easily welded with this technique without being exposed to distortion. However, copper planch and aluminum cooling fin are used in the method to reduce heat input. Semi-automatically welded 304L austenitic stainless steel sheet materials were compared with manually welded stainless steels and the results were evaluated.
