[MW:22611] Re: TG-X flux core TIG rod

hye pravin. AS TG X flux cored wires are used as an alternative of purging and the Slag is produced because these filler wires are flux cored. For 4-5mm thickness set your amperage to about 80-90 A. Just like FCAW this slag is a fused slag, there is no need to remove it. But if you want to remove slag from your weld job then find other alternatives in http://www.weldpedia.com/2014/04/five-alternatives-to-eliminate.html

Dear Expert,

I'm having issue on removing slag on root pass welding for stainless steel pipe welding

Welding condition:

Material: SS 316L

Thickness: 4-5mm

Bevel angle: 65 deg

Root opening: 3-4mm

Root face: 1mm

Pipe dia: 4 inch

I'm using KOBELCO TG-X316L FCW TIG rod, special consumable which can eliminate back purging which save cost on Ar.

However, it is difficult to remove slag on inside the pipe.

Kindly advice if anyone have experience using TG-X from KOBELCO and how to remove the slag inside the pipe.

Best regards,

Pravin Poornachandran
