Dear Sir,
Do you have any proof that this method works besides the vendor’s claims?

Dear Praveen,
You may also apply high frequency hammering technologies like Pneumatic Impact Treatment during welding in order to control the amount of distortion.
With such technologies you can reduce distortion up to 50% when applied on every separate weld layer.

Dear,
Distortion occurs when the Stress occurs due to Thermal Expansion or contraction exceed the Yield strength of material.
Factors affecting distortion, are:
1)Parent material properties
2)Amount of restraint
3)Joint design
4)Part fit-up
5)Welding procedure
Controls:
1) Preheating
2) Use of Stiffeners,Welding Jig & Fixtures, Flexible clamps.
3) Intermittent Welding process
You can control the distortion by keeping these points in mind .
You are recommended to use ER 309 L.
Regards,
Vineet Kumar
