In other words you need to have one of us either send you a WPS or write one up for you? No worries, I take Visa or MasterCard credit cards, and my rate is $200/hr.

Do what? Do you think having to provide a WPS or even draft one is free? Of course, if the original poster decided to Google on how to write a WPS I am sure they could figure it out. Nahhhhhhhh.

From his previous posts the original poster should have been capable of writing his own, I am surprised you would even offer,
when it looked like the poster could not be bothered to do basic research.
I also know there are times on here when you are generous to a fault with information.
B.E.
You are judged not by what you know, but by what you can do.
I do not think that the intention is that others have to make one wps for him on this forum .
if he wants to have , if necessary, he must look for a external company .
I think I might have made a mistake in my request and there's been some misunderstanding .
I really know how to write a WPS but I have problem with WPS for repairing welds and casts which have some defects:
- Is there any difference with common WPS and WPS for repairing
- How PQR is done for WPS for repairing
- My employer did not accept any of our WPSs for repair welding and I need to show them a sample from outside the company
moreover I have to emphasis that I can't find any sample for WPS for repair welding.
please refer to ANSI/AWS D11.2-89 (R2006) :Guide for Welding Iron Castings
under section 8: Welding Procedure and Performance Qualification.
the Table of Contents of this guideline can be download from below link address
The WPS would be qualified, if necessary, in the same manner as any WPS. The base metal used would be selected from the same material group or it would be of the same material being repaired. Everything else would be the same, i.e., essential variables, etc.
When I develop a repair procedure it include the method of excavation the general shape, i.e., width versus depth ratios and radius at the bottom of the excavation. I often depict the general placement of the weld beads to control the heat input of the first couple of layers when the size of the heat affected zone is important and whether the beads are stringers or weaves. If two welding processes are to be used, again in some cases where heat input is important, I show the depth to be deposited with each process. I believe in sketches to show the welder what is expected. Generally, the preprinted formats included in many welding standards do not lend themselves to the type of WPS I develop. My entries include more detail than one or two words.
I was involved in a project that required the repair of steel castings measuring 8 inches thick. The cracks extended about three inches into the thickness of the casting. We had the good fortune of makes some changes the cast steel frame that required the removal of some thick sections. The piece I selected was 12 inches thick by about 14 inches square. I milled a groove into the casting that replicated the shape of the excavation I expected to use for the actual repair. The groove was welded using the proposes welding procedure that included SMAW for the root layers and FCAW for the fill and cover. The welded sample was tested using UT, guided bend tests, and reduced section tensile tests. Due to the thickness of the groove weld each side bend was subdivided into three pieces consisting of a piece representative of the bottom third (including the root layer), a piece representative of the midsection, and a third piece representing the top third of the thickness. In all twelve pieces were subjected to side bends. Likewise, the reduced section tension specimens were subdivided to represent the root, midsection, and top portion of the weld. In total, six RST tests were performed.
