When TIG welding stainless steel, the selection range of welding current is usually between 50~250A.
For TIG welding of stainless steel, the selection of welding current depends on multiple factors, including plate thickness, welding position, and specific welding requirements.
The relationship between steel plate thickness and current
In general, for thin plate welding below 6mm, the welding current can be adjusted between 50~150A to ensure that the weld seam is aesthetically pleasing and the welding deformation is small. For thicker plates or special welding requirements, the current can be increased to 150-250A. In addition, the selection of welding current is also influenced by the welding position. For example, when performing butt welding, in order to ensure the quality and stability of the weld seam, it may be necessary to adjust the welding speed to adapt to different welding currents.
Precautions for practical operation
In practical operation, the specific value of welding current needs to be adjusted according to the actual situation to ensure the quality and safety of the weld seam. Meanwhile, the selection and use of shielding gas, the angle and position of tungsten electrode, and welding speed are all important factors that affect welding quality and need to be comprehensively considered.
In general, when TIG welding stainless steel, the selection range of welding current is relatively wide, and the specific value needs to be determined according to the specific welding conditions and requirements. In practical operation, it is also necessary to pay attention to the adjustment of other welding parameters to ensure welding quality and safety.
