API 5L X70 welding filler metal - Welding, Bonding ...

eng-tips› …› Welding, Bonding & Fastener engineering ForumAug 12, 2006· API 5L X70 welding filler metal fakhmed (Mechanical) (OP) 8 Aug 06 08:05. Dear All, Can some body help me to determine the filler metal type to weld API 5L X70 pipe thickness 18mm with FCAW and SMAW process. Thank you . RE: API 5L X70 …You may wish to consider that Ed Craig of weldreality in his page weldreality/ASTM_API.htm recommends E7018 and E71T-1 welding-advisers/I would not use 70 tensile strength filler metal as X70 has a minimum tensile strenth of 82 ksi. You might achieve that based on what brand/type of consumable you use, but not probable. I assume you are not going to PWHT. In that case, I would use either E81T1-K2 (more than 1% Ni, so make sure NACE requriements for sour service are not imposed), or 8018-C3.Thank you but different type of electrodes. Why not E8010G without PWHT?fakhmed, As in most situations, there are numerous choices that will work. I've done as GRoberts has suggested and qualified a procedure using a low Ni electrode, but, Lincoln recommends among other things, 8018G. As to PWHT, you'll have to evaluate whether or not this is necessary based on other criteria.8018-G really means nothing by itself. It just means it ia 80 minimum tensile strength, and of any chemistry. It could be a 12 Cr creep resistant electrode for all the 8018-G classification tells us. Each -G electrode has to be evaluated seperately with input from the manufacturer. There are literally tens if not hundereds of different kinds of -G electrodes out there, and they are all for different applications.I've ordered already E81T1-K2M wire 1.2 and 1.6mm and we will proceed the welding with 80°C preheat and without PWHT for the pipe 1200mm diameter and 18mm thickness. What is your opinion?I've done X65 with that wire with PWHT, and still had plenty of strength. You should be fine with that combination.Now the question is if the PWHT is necessary for such weld or not. The API 5L is not so clear Best regardsAPI 5L is the standard for manufacturing the pipe.
