Re: [MW:5724] How to demagnetise the tube sheet?

Hi, pls try welding as AC polarized rod. This will minimize the arc blow.

Subject: [MW:5720] How to demagnetise the tube sheet?

Hi Members,

 

We are suffering a problem in tube sheet. The tube sheet is P5A material (SA 336 Gr F22 CL.3) is magnetised.

 

We are not able to proceed the GTAW welding of tube to tube sheet.

 

We are not sure how it is happened. How can we demagnetise the tube sheet.

 

It is around 275 mm Thk and 3 mtr dia.

 

Kindly request the solution from experts.

Thanks & Regards
Muhammed Ibrahim PK
