Re: [MW:22608] TG-X flux core TIG rod

Hi Pravin,

It is common fact that while using TG-X filler the slag will be there inside the pipe and it prevents the weld metal from oxidation and thats what it is know for. Removing slag is not possible by mechanical means, you may flush the line with water or steam before hydrotest. You may do industrial etching after consulting with your client.

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
