    Aug 12, 2006 · RE: API 5L X70 welding filler metal GRoberts (Materials) 8 Aug 06 11:50 I would not use 70 tensile strength filler metal as X70 has a minimum tensile strenth of 82 ksi.

    You may wish to consider that Ed Craig of www.weldreality.com in his page http://www.weldreality.com/ASTM_API.htm recommends E7018 and E71T-1 http://www.welding-advisers.com/
    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 regards
    API 5L is the standard for manufacturing the pipe. Are you inquiring about seam welding in the shop, or girth welding in the field? Steve Jones Materials & Corrosion Engineer http://www.pdo.co.om/pdo/
    This standard is required by our customer to manufacture from welded pipe some fittings (Elbow, Tee,...) Diameter 1200mm Thickness 18mm.

  5. Welding on High Yield Pipe - Lincoln Electric

    This is one approach to the welding of X80, where hydrogen cracking in the parent steel is not a concern for the root pass, but weld metal hydrogen cracking could be a concern on subsequent passes. In shielded metal arc welding shielding is generated by the decomposition of the flux at the arc.

  9. What's the meaning of API 5L for line pipe? - Quora

    API standard for pipeline. API 5L pipe production is currently using micro alloy heating treatment process. The production costs of seamless stainless steel pipe are significantly higher than the welding pipe and with the increase of steel grade, the limit of carbon content is more and more strict.
