Re: [MW:14379] Range of approval for WELDER qualified to weld grove welds according to API 1104

Hi Mr.MaleMela,

 

if the welders can really produce sound Fillet welds as per your spec requirement, then you can send a concession request with proper evidence and justification to your client for the accepatnce of fillet welds, when the welders passed Groove Welds.

 

If they do not agree, then you have to test them with fillet welds.

 

 

 

Just try this.

 

Cheers,

Sarav

Hi Colleagues,

 

I am working on a pipeline construction project in Mpumalanga –South Africa. The client is a reputable water utility company in South Africa who has appointed a contractor to construct 37 km of 610mm Diameter pipeline. The joint design is Partial Joint Penetration ( by means of fillet weld). The pipe fit up is spigot and socket joint.

 

The appointed inspection authority is refusing to accept welder qualification for 'v' grove joint design allegedly because the client specification has asked for fillet weld and NOT butt weld.

 

Requalification of welders is not an issue apart from the time it will take to set up and get the qualification test done. I also know from training that range of approval for grove includes fillet welds as well.

 

Should I simply re-qualify the welders although their qualification covers fillet welds if range of approval is considered or should I insist on the inspection authority consulting for proper information on this matter?

 

The integrity of the profession is under threat if people without proper knowledge are allowed to rewrite the specifications for the industry and go unchallenged.

 

Your urgent response will be greatly appreciated.
