Weldment Asian Supplier help

Date 02-02-2006 00:35

Recently my employer out-soured several of our weldment because we were not able to keep up with demand and to explore the cost savings. The problem that we are experiencing is that some of our Asian suppliers cannot produce weldments that meet our spec. (Based on the D1.1). Multiple macro-etch audits are revealing to us that the supplier is not achieving fusion to the root on flare-bevel groove welds (on 2” to 2.5” X .25” .18” wall A500 welded to .75” flat bar (A36). We’ve sent them process procedures with tight parameters, yet they still insist that they cannot produce acceptable weldments, Even though we use the exact same procedures here and do quit well the majority of the time.
My employer has mandated that the Asian suppliers hire weld Engineer or Technician to help them solve the problems. I was asked to build a profile to help them interview for this position. The challenge that I have is that I’m not familiar with the educational certifications in that area.
Please, review the profile that I’ve created and give me feedback.
This bulletin board is the best mentor that I’ve have since I became CWI/ Weld Tech in ’99 and I’m hopeful that y’all will be able to enlighten me. Thanks in advance for the feedback

Suggestion: why don't you try Brazilians suppliers? There are first class welding shops down here (pressure vessels, pipe and structural steel prefabrication, platework etc.) that employ first class welders approved by ASME IX, AWS D.1, API 1104.
I can give you a hand, if you wish, with no financial interest from my part (commission on sales, to speak clearly). I'm a University professor, not a businessman. It'll be a pleasure to make a favor to you and return to the welding shops I'm speaking about the favors they've made me over the years, as, for example, preparing welded coupons to be tested by my students at the university metallurgical lab.

You may want to be more specific about where you are having work done in Asia. There is obviously a great difference in the way things work in say South Korea as compared to Pakistan. This may help you obtain advice from people with specific knowledge of the country (or countries) in which you work.

Check the requirements of D1.1 for flare bevel groove welds. Fusion to the root is not a requirement. The maximum weld size is function of the flare radius. Don't confuse the flare bevel groove weld with a simple fillet weld.

AWS D1.1 allows a larger weld size only if the procedure is qualified to demonstrate the ability to "penetrate" deeper into the flare bevel.

What is the welding symbol calling for?

Have bags, will travel.
