Materials & Welding: Re: [MW:22595] TG-X flux core TIG rod

Thursday, December 18, 2014

I hope there is no any other method for removing slag in side the pipe..we have to do air blowing are water flushing after completion of the welding.

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
