Dear Experts,
We are preparing to tack weld weir screen to frame per design specification. And We find that,Once welder start the arc using the GTAW(TIG) and move it near to the joint between the screen wire and the frame, the wires fuse instantly and break ,even we adopt the minimum current .
1.Wire Diameter：1.2mm
2.Material: 304L stainless
3.Process: GTAW without filler metal.
Any suggestion or comments will be grateful.
