Materials & Welding

You need to know about the design codes of the equipment to perform NDT inspection, for example:   ASME B31: For piping and pipelines ASME VIII: For pressure vessels AWS: For structure, D1.1 Carbon steel, D1.2 Aluminum, etc.   In some cases specific codes apply, for example API for oil & gas, NBIC for pressure vessels, etc.   Previous NDT you need to read the "Scope Chapter" of each code, standard, norm or reference document, and you will find relevant information where the document apply: materials, thicknesses, kind of structure, limitations, etc.   Best Regards…   J.

Dear all, Pls.let me know material P1 qualify Welder can weld P11 if yes how or no how, for eg. P no., F no. , as I know P1 to P15F qualification range as per sec IX Thanks -- https://materials-welding.blogspot.com/ https://www.linkedin.com/groups/122787 --- You received this message because you are subscribed to the Google Groups "Materials & Welding" group.

Dear Harish, Here the material is supplied by client and it has been in the yard for some time. I just wanted to know what is the required tensile strength for the PQR. Regards, Jose On Mon, Sep 11, 2017 at 8:21 AM, Harish Kannepalli < harishkannepalli@gmail.com > wrote: Hi,     First of all please remember that these are engineering steels, which means the mechanical properties can be adjusted as per customer requirements. So to qualify the procedure you should first simulate the PWHT parameters on the raw material and test the mechanical properties. Then weld the material, do PWHT and test it. Hope this clarifies.

Hi Emilio, Please see the catalogue as below. If may have all the relevant information including the recommended welding consumables.   Thanks.   P.Goswami.P.Eng, IWE.   http://www.totalsteel.com.au/downloads/JFE-EH-Catalogue.pdf   From: materials-welding@googlegroups.com [mailto:materials-welding@googlegroups.com] On Behalf Of Emilio Cerato Sent: September 10, 2017 11:44 AM To: Material Welding <materials-welding@googlegroups.com> Subject: [MW:26807] Weld JFE EH500   Dear, I have to weld a material identified as JFE EH500.   According to the supplier's catalog recommend using ER70S3 or ER80S3 wire, controlling preheating and heat supplied.   This work is for a mining company, in which I have no manufacturing standard The question is how do I qualify the procedure?   What is the resistance of the tensile test? With what punch diameter should I make the folds? Is it advisable to use AWS B2.1?   I appreciate your comments. Thanks. Em...
