WPS needed for weld-on masonry anchors?

WPS needed for weld-on masonry anchors?

(OP)
Is a WPS needed when placing weld-on CMU masonry anchors?  If not is there a general standard anywhere for attaching these?

I see these things being welded on all the time and talk about your buggered up welds..these things meets none of the requirements of D1.1 Fig. 5.4 and arc strikes from top-to-bottom.  These guys never met an arc strike that they wanted to incorporate into the weld.

Helloooooooooooo !!

Not a good question?

RE: WPS needed for weld-on masonry anchors?

What is a WPS?  

Provide more information on your question.  Are we talking about headed studs to embed plate welds?

Maybe a picture would help.

RE: WPS needed for weld-on masonry anchors?

I expect the Engineer, i.e., the Owner's representative, to require any attachment welded to the structural frame to meet the applicable code whenever the state or municipality adopted a building code that incorporates D1.1 directly or by referencing another design code that includes a reference to AWS D1.1 or other welding code.

One must consider the affects of the welding operation of the structural member, not only the attachment itself. Welding, if not done properly, can affect the mechanical properties of the structural member. Welding can also introduce unacceptable defects that could affect the structural integrity of the structural member.
 
The WPS is not a magically or mystical document. It is simply written instruction to the welder informing him what process, what base metals, what filler metal, etc. is to be used.
 
I can think of a host of things that can go horribly wrong when proper consideration is not given to a weld or when the welder is not provided with proper information. One problem I encounter is that some contractors and engineers do not understand the purpose of the WPS and hate to spend the time and money doing the necessary research to properly document the welding requirements.
 
The bottom line is that I expect all welding that involves a structural member to be covered by an appropriate WPS. Until the Engineer waives the need for the WPS, I expect to see one on the job-site and I expect the welder to implement it.

WPS = welding procedure specification

weld-on CMU anchor allows for placement of an adjustable dovetail type masonry anchor

Al - while you and I appear to be in agreement I am the least senior CWI on the project.  You can see where that's going...........

RE: WPS needed for weld-on masonry anchors?

Boffin,

I sympathize with your pain, as I am not the most senior guy in my office either and sometimes get shot down on valid points.  

However, least senior or not, you're still a CWI, and one that I'm assuming whose name will go on an inspection report at some point in time.  

Make your voice heard about demanding a WPS.  Explain it can only do good.  Plus, if a welder doesn't follow the qualified WPS (and you document that) and something happens down the road and through forensics they deremine it was due to such and such masonry dowels being improperly welded, you don't own it.  You did your due dilligence.

To me, those few peices of paper are worth me sleeping soundly at night.
