[MW:8393] Powerwave technology

By Materials & Welding
Hi Friends

I would like your opinion on Powerwave Technolgy Power sources if you have used the same.


Full penetration Butt welds are achieved with Wave form control technology.

Power source manufacturer claims that a square butt joint upto 19mm thick can be welded with one pass from either side and eliminate Back chipping ! This is done by a single wire SAW.

Is this possible ?

Our objective is to weld a L/S, C/S butt joint in a 19mm thick CS shell and eliminate Back chipping, WEP. NDT is 100% RT.

Can this be done by using Powerwave technology SAW powersources as claimed by the power source manufacturer ?

Till date we have welded upto 10mm thk shells with square WEP by SAW ( one pass from each side) and without Back-chipping, this has been done by our normal conventional SAW powersource.

Please share your views on power wave technology for SAW and whether upto 19mm thk butt joint can be welded without any WEP and back gouging by this powersource .

Regards
