Dear Pradip, Thanks for your help, but now, I want to know, is there any requirement to use postheating or slow cooling down by a heat resistant blanket such as asbestos after welding of A517 steel? Thanks.

Hi Kianoush, Attached are some guidelines on A/SA-517 steel. This steel is a Q&T steel contains various alloying elements (different grades have different compositions). Welding of this steel would require a precise control of heat input and welding parameters and correct selection of welding electrodes. Generally there's no electrodes of exact matching chemistry for this steel. However if I have to make a choice , the preference would be either E-9018/10018/11018M SMAW electrodes and matching GTAW, GMAW and SAW filer depending on the process and extent of fabrication involved. Many fabricators may prefer E-9018/10018/11018G (General Low Alloy Steel) electrodes, but if the desired chemistry is specified beforehand, so that there would not be any later surprises? What's the design code ? For fabricating A-517 steel one has to incorporate strictly the design code requirements. Let me know if the attached information helps you or not?. Thanks. Pradip Goswami,P.Eng. Welding & Metallurgical Specialist & Consultant | Dear All, Is there any experience on welding of A517-Gr.B with thickness up to 20 mm? Thanks,
