Note that ISO definition of heat input is different from ASME, with ASME HI defined as arc energy by ISO. I am going by the ADME definition here same as everyone else, assuming that is the language you use. Irrespective of this I am amazed that this question gets asked so many times. A WPS is a...

Kardo-Lincoln and Esab-I vaguely remember it as Ok53.xx In any case these free iron buffers have been used in the past only for ss and experience on inconel is limited. The welding of three different layers needs a lot of skill especially to minimise dilution when depositing the buffer layer...

In addition to Metengr's recommendations 1. HI should have both min and max restrictions as these influence the % ferrite/austenite 2. Most single sided butt/groove welding procedures for DSS for corrosion resistance will need high purity Ar backing with oxygen level monitoring using purge...

The best is to use a tong tester and use it close to the point of welding on the return cable (Earthing) Thanks and regards Sayee Prasad R CEng MWeldI MIOMMM If it moves, train it...if it doesn't move, calibrate it...if it isn't written down, it never happened!

Only thing to remember and ensure that the PWHTtemperature is lower than the tempering temperature of the Q&T for F65 Thanks and regards Sayee Prasad R CEng MWeldI MIOMMM If it moves, train it...if it doesn't move, calibrate it...if it isn't written down, it never happened!

See NACE MR 0175, page 14, clause 5.2.1 states "Overlays applied to carbon and low alloy steel or to martensitic stainless by thermal processes such as welding, silver brazing, or spray metallizing systems are acceptable for use in sour environments, provided the substrate does not exceed the...

MJC ypically a T to T/sht weld can be a seal weld if the expansion of tubes into grooves in t/sht is giving the strength. However it is possible to use welding for strength and expansion of tubes for strength as well and in rare cases both expansion and welding contributing to strength. Refer...

NiM: Do it right the first time, everytime, and ON TIME!!! Keano: "If its not written down it never happened." Which I read somewhere else as "If it moves, train it...if it doesn't move, calibrate it...if it isn't written down, it never happened!" "Imagination is more important than knowledge...

Bagnamento's question was probably misunderstood. ASM clearly defines stabilized annealing for 321 tyope materials as folliows "It is carried out where maximum corrosion resistance of stabilized stainless steels of type 321 is required. The heat treatment involves heating to the range 1550-1650...

During welding of cs pipelines (API 5L X 52-65 grades) especially the residual magnetism is the pipes (due to say induction heating during the coating) could cause problems during welding. Now traditionally, the equipment for demagnetising are AC equipment. I was told however that the welding...

Sorry ladies, no offense meant. In any case, I did not Ass/U/Me that females were/were not following this thread. And I do not think that my mail was so offensive, however apologize if anyone felt so! (Though I will unabashedly agree that Arun's reply to my post made me cringe the whole of...

Arun <<<<<<<<< Fortunately there are no women participants. Or else we would be labelled mcps(courtsey list 21) What if the husband snores ,wife too has a right to protest like mine. (We re married for almost 20 years!!) >>>>>>>> "We're married" or "we re-married"??? That made me momentarily...

History Economy of the country/region Cost of living Population of country and as a result, available oppurtunities i.e. supply and demand for engineers Competition Number of institutes offering engineering Cost of education All the above are some of the differences in the regions leading to the...

I have successfully welded cupronickel(90:10) with matching consumables. However, there are two reasons put forward for using 70/30 as the weldmetal for the material. The first is that considerable coring can occur in the 90/10 weldmetal thus giving denuded regions which corrode preferentially...

RHoran If you look at the essential variables, they are different in case of both codes. But the tests specified are similar especially for the welders. So you should be able to club requirements of both codes in such a way that the PQT tests meet the requirements of boith codes. Then you will...
