regareding taper burning of electrode

[akshay]

Hi

I believe it's due to non concentric flux coating of electrodes. It's a manufacturing defect.

Take few electrodes from the pocket inspect visually and measure it's flux coating thickness through vernier caliper and you will find uninformed coating.

Dear Friend and Expert

 

Regarding to Radiographic Testing (RT) of weld

 

1)     Does any codes / stands mentioned how to selection of film type/class like carbon steel and stainless steel?

2)     On the heavy wall thickness plat 70 mm (Sphere Tank) welded by SMAW testing by PAUT were found a lot of defects but re-test by RT Ir-192 doesn’t found any things, Any opinions to recommend

 

 

Thanks and Best Regards
