[MW:18743] FIXTURES TO PREVENT DISTORTION IN WPQT PROCESS

Dear Experts,

We want to qualify New PQRs in various Positions using FCAW-S and SMAW (Different procedures). The details are as follows

Code AWS D1.1

Material – S 355 KT 20

Thickness – 50 mm

The PQR required for immediate cooling after welding. ( 250 Degree to 50 degrees)

I am planning to use Fixtures to prevent distortion.

Is there any restriction to use Fixtures to prevent Distortion in WPQT process ?

Appreciate your advice

Thanks and Regards,

Tomy George
