Re: [MW:23165] Re: Weld Map - WPS PQR

Dear Vinod,

let me ask you a Question.

Incase, the WPS No. & the Joint No. is not prescribed in fabrication Dwg, 

and if you have 20 no. of weld joints in a Vessel, which is to be welded with 3 different WPSs,

for example GTAW only for below 3" Nozzles , GTAW + FCAW combination welding , GTAW + FCAW + SAW combination for Long Seams ,

you have to give each Joint No. , the applicable WPS No. for that Joint and NDT method for those joints, that is the reason that the customer is asking for a Weldmap .

If customer requests you to issue Weld Map , then you have to submit it and to make them understand with full details of Welding .

Simply submitting only the WPSs for all of the 20 No. of weld joints would make confusions and mess, even to your own fabrication team also.

Regards,

Saravanan,

Not required. Joint details can be shown in isometric drawing with joint details

Hi all

Weld mapping is the process of assigning information to a weld joint to enable easy identification of its design (WPS), production (welders, their qualifications, date welded), quality (visual inspection, NDT) and traceability (heat numbers of materials joined & welding consumables). 

Weld mapping should also incorporate a pictorial identification to represent the weld number on the fabrication drawing, in case the designer does not nominate a weld number. 

To manage this multi-stage labour intensive record keeping activity, cloud-based welding management software such as Smart Welding Manager, with its Android and iOS tablet apps will reduce the workload and minimize the errors as it distributes the work across the production hierarchy.

Respected Experts,

Had a discussion at a customer site on subject.

Is Weld Map a must for each - WPS PQR, like a vessel fabrication drawing has?

Please share, some knowledge. We need to weld process pipes ranging from 2" to 16" (seamless sch. 40 to sch 160) and hence the request.

Best regards,
