TIG Wire

 

Introduction:

It is TIG wire for 450-500MPa grade carbon steel. With good welding technical performance, beautiful forming, well-flow molten iron and good crack resistance.

 

Usage:

It is for welding 450-500MPa grade strength carbon steel and low alloy steel, such as bridge, vehicle, building, pipeline, and etc.

Notes

1.     Protection gas flow requirement: 7-12L/min while welding current is 100-200A; 12-15L/min while 200-300A.

2.     The extension length of the tungsten electrode should be as short as possible relative to the nozzle, and the arc length should be 1-4mm (2-4mm for welding carbon steel; 1-3mm for low alloy steel and stainless steel welding)

3.     It adopts windproof measurement while wind speed is above 1.0m/s.

4.     Strictly remove grease, rust and moisture impurities while welding.

5.     Welding linear energy directly affects mechanical properties of welding seam metal and crack resistance performance, etc which should be paid more attention to.

6.     The above points are taken into reference.
