Hi   This calculation as given below is used but is extremely conservative resulting in much higher preheat temperatures than what is actually required.

using 10mm strip will be as good as using FCAW technique (even you will have more wide width in a single pass using FCAW). Can you explain why you are looking for this option.... you can make FCAW mechanise which can solve your problem of productivity or quality..... I have used 30mm strip and that is readily available in market. You can keep 400-600 Amps based on your requirement of fusion and dilution and type of equipment you use. Even for 30mm you can use the welding head which is being used or 60mm wide strip. Regards.

I dont know your application,but in my experience in oilfield production work "Brother-in-law" (one welder on each side of pipe) is used in almost every situation if conditions permit. This speeds up the process and keeps the heat more uniform, I have brother-in-lawed a lot of four inch schedule 80 running frac. and schedule 40 for sales lines, have done this up to twelve inch.

Jaspal The requirements for determining the A-number are located in QW-404.5. There are several options available in this paragraph. I would suggest that for E7018-1 (There is no designator "I" that I know of) that you use A-No. 1. This is permitted by QW-404.5 (b) which states that "For SMAW, GTAW, and PAW (the chemical composition can be determined) from the chemical analysis of the weld deposit according to the filler specification or from the chemical composition as reported either in the filler metal specification or the manufacturers certificate of compliance." I believe that the code is concerned with the composition of the undiluted weld deposit chemistry when the filler metal has an A-no. (See for example Section II Part C SFA-5.1, 9.3 or Figure 1 which specifies that the chemical analysis shall be made from undiluted weld metal). The rational, of course, is that a filler metal of the same A-no. will result in a deposit chemistry that has similar propert...
