Welding - WPS and PQR per AWS D17.1 Questions

[jameslaz]

Hi All,

I have been tasked with getting our welding department up and running and I need a little help. I am hoping someone out there with more experience can help. I have been reading AWS D17.1D17.1M:2010 and form what I can see I need to develop WPS’s for each weld we do that can then be added to a traveler as work instructions. I am not too sure about the PQR, I know that it is the qualification for the weld procedure and that makes sense but it stated in AWS D17.1/D17.1M:2010 5.4.2 Procedure Qualification ‘Qualification of weld settings for manual welds is not required”. All the welding we do is manual does this mean we don’t need to create PQRs for each process?

Also would someone clarify AWS D17.1/D17.1M:2010 3.0 Terms and Definitions, Engineering Authority. We are a subcontracted machine shop and we take order from first tier and end user customers. If a customer gives us a print that states weld per AWS D17.1 Class B, who is the engineering authority?
Thank you,
James

We have WPS and Engineering service company, e.g. INTERTEK do PQR for us when we have welders apply for EN or ASME certification

hope it help some

Thanks for the input, I have a better grasp but still need some help. In AWS D17.1/D17.1M:2010 5.4.2 Procedure Qualification it states ‘Qualification of weld settings for manual welds is not required”. All the welding we do is manual so how does this relate to us? I see where it says all welds shall have a written procedure and several places state we need WPS’s and PQR’s but the statement in 5.4.2 is very confusing. I am currently reading though AWS B2.1/B2.1M:2009 for more information but so far I am just more confused. Is there a welding engineer and quality person out there that knows more about this that can shed a little light for me. I need to write an internal procedure for qualifying welders and welds and I am not sure of all I need to do.

Thank you,
James

Your organisation will need to hire a consultant welding engineer to assist you in defining the welds WPQR and WPS, and act a independent third party approver of your welders.


Try contacting the AWS (http://www.aws.org) they should be able to assist you, I have no experience in the Aerospace sector only oil and gas, structural and would have been only too happy to supply WPQR templates etc to help but your AWS D17.1 spec is a unknown to me.

Weld settings are those that the welder has direct influence on while he is welding (hood down parameters), for example, current, arc gap, travel speed. Those parameters that are fixed prior to him initiating the arc (hood up parameters), such as electrode type, cup size, etc are still required to be specified in the procedure

I agree with above post. You need to hire welding engineer.

I would suggest sending someone with welding experience to the AWS CWI seminar (it's a week long) and then take the exam. It is fairly intense, and you must document relevant experience in the industry before you can attend. All the information is under the certification tab of the AWS website.

In answer to your question about settings for manual welding do not have to be recorded, that means as you are developing your PQR/WPS that you do not have to record the specific settings on your documents w3hen you are performing manual welding because the finite setting for the welding is handled by the foot/hand control of the torch. When you are performing automatic/semi automatic you have to record those setting parameters.

In answer to your question about the Engineering Authority, the Engineering Authority is held by the activity that developed the drawing, unless it is delegated in writing to your facility.
