What does "E7016" mean? What should I pay attention to when welding? Can I weld the pressure vessel (pressure 1Mpa)?
The electrode E7016 is American Welding Society AWS grades, the tensile strength of 470MPa, yield strength is 390MPa, the impact toughness of 100J (-50 C) section, the elongation is 30%, and the yield strength and tensile strength of the national standard J507 (E5015), so this electrode can replace J507 (E5015) electrode, is resistant to ultra low moisture absorption hydrogen electrode, excellent low temperature impact properties, using direct reverse, used for all position welding. Look at the electrode welding electrode has not expired, no quality problem, and then the electrode drying (350 DEG C for 1 hours), more than 3mm thick plate to groove, welding parts to rust, water, oil, dirt, can pressure vessel welding Q345R, 16MnDR strength is plate (as for the pressure, according to the the design requirements of 1MPa or greater pressure can be, but the thickness is different).
E7016 is AWS model, the national standard model is E5016, is a common J506 low carbon steel electrode, used to weld medium carbon steel and important low alloy steel;Welding notice:1, drying before welding, drying at 350 degrees for 1 hours, with the use of baking;2, welding parts must be completely removed before welding, oil, rust, moisture and so on;3, using short arc welding, narrow welding method;It can be used for AC and DC and reverse connection at DC time.It's possible to weld pressure vessels. 1MPa is too small.
E stands for welding rod, 70 represents tensile strength of weld metal, 700MPa is 1, welding rod is suitable for all position welding, and 16 is low hydrogen direct current.
