From an ASME Section IX Code stand point the below statements are not correct.   On should read the Section IX, QW-409.1, interpretations (there are quite a few).  In particular one should Interpretation IX-81-91.  However, I will transcribe portions of several interpretations that are interesting:   IX-81-19 Q4 – “If QW-409.1 does not require that average heat input be determined” {previous question – reply No} “how is heat input established for multiple pass procedure qualification?  Must it be established for each pass? R4 – QW-409.1 requires requalification when an increase in heat input occurs over that qualified.  Maximum heat input is established during procedure qualification by determination of the maximum amperage and voltage in combination with the least travel speed or, alternatively, the maxi mum volume of weld metal deposited per unit length of weld.  Heat input is not required to be determined for each...

Hi, There is no code specify the shelf life of electrode, its depends on the manufacturer recommendation. I had also faced the problem with Lincoln electrodes certificates, as they mention in the lot certificates in 1 year. So raised the quarry in Lincoln Company about the shelf life of electrode; accordingly they send the warranty/validity certificate (Here I attached the attached warranty/validity certificates & lot certificates -for your information) So when ever you face the shelf life problem with electrode kindly contact the manufacturer and get the validity confirmation from the company. its the only record or proof of electrode shelf life and solution.

Dear Israr,                PMI  is technique for fast identification of materials. When it is used for accurate measurements of chemical composition, problems arise. If you observe the standard deviation beside the reading, you may understand the reason for this variation. In XRF, the reading is given by the electron signal generated by the incident X-rays, so during X-ray irradiation the number of electrons removed may vary for each reading taken; the detector noise may also affect the reading. As a precaution, please use the PMI at max. temp of 40°C beyond which detector has more noise signal. 2011/1/31 israr ahmed < ahmedisrar.nm@gmail.com > Dear All,   I had Witnessed a PMI test on Material 34CrNiMo6 The Cr. % obtain 1.3 to 1.4, After Machining the Rod and Heat treatment and temparing the same material is tested fore PMI and found Cr.0.98 to 1.2 Percent.The Cr. % become less by 0.1 to 0.2 %.

Hi At the first,it is important that the mechanical properties of chosen material be the same, the yield point and the tensile point of A36 is the same for all thicknesses, But there is a little difference about the material (Specially sheet metal) that is categorized by EN 10025 like s235 becuase the yield point of the s235 that is similar to A36 (almost) is going down when the thickness is going up but the issue that is very important is the Design assumptions. I can send you the summarized properties of the materials if you want but the final decision must be taken by the designer and accorting to design assumption. regards M.R On Jan 31, 4:52 pm, Srinivas Engr < srinivas.gmsr...@gmail.com > wrote: > Dear All. > pl guide be about in selction of equivalent grade material? > Wat we have to look? > & In which spec we have to refer? > Wat r A36 equivalent materials..? > Wat about S275 grade material? > > Thanks & Regards > Srinivas -- To pos...

However as a good practice and based on electrode manufacturer's guidelines it may be worth considering:- · Solid Wires, GTAW/GMAW-No shelf Life...

Mr. Praveen , You are correct definitely we can not get El 46% but we can get YS and TS with base metal matching by that way it will pass in TS and naturally it will pass impact at -10 deg C so PQR will be passed.

I think such a requirement is very unusual, you can match the strength part, but I think its going to be a difficult task in locating a consumable to give you 46% elongation. Wish you good luck!
