[MW:4374] RE: 4338] Robot - WOPQ?

which of these is true in your case. in my opinion for 1 below no WO hence WOPQ not required

1. Welding with equipment which performs the welding operation without adjustment of the controls by a welding operator. except for the loading and unloading of the work.

2. Welding with equipment that has controls that are manually adjusted by the welding operator in response to visual observation of the welding, with the torch, gun, or electrode holder held by a mechanical device.

Dear All

We have a typical situation.
We want to do overlay by FCAW and want to deploy robot for this i.e by automatic welding.
The construction code is ASME Sec VIII Div.1

Now as per ASME Sec VIII Div1, UW29(b)(2)-- "when welding is done by any automatic welding process, performance qualification testing is not required".
So do we need not do any WOPQ ?? Is performance qualification required or not ??
Pls.. advise..

Regards
