What type of welding rod is used for welding 16MnD?
16MnD read as low as sixteen mn. Belong to sixteen Mn low temperature steel.Can useBrand: J507FeNi (model: E5018-G) basic electrode welding.The electrode belongs to a low hydrogen and sodium alloy structure steel powder welding rod. DC reverse connection. All position welding.It has good low temperature impact toughness. Used for welding of medium carbon steel and low temperature steel pressure vessel. Such as:16MnD, 16MnDR, etc..
J507, preheat 150 degrees before welding, choose different welding current and voltage according to different wire diameter.2.5, 3.24575-100, 110-130, 150-165, 230-250
Using J507RH welding rod.DC reverse connection.Preheat about 100 degrees before welding.When the plate thickness is less than or equal to 20mm, the V type groove is opened and the U groove is used when the plate thickness is greater than 20mm.Current: Phi 3,2 welding rod A=130-150, Phi 4 electrode A=180-200, Phi 5 electrode A=230-250.Conditional, should be done after welding stress treatment.
