E5015: belong to low hydrogen sodium basic welding rod, direct reverse welding.J507:J507 (J48.57) conforms to GB E5015, equivalent to AWS E7015Description: J507 is a low carbon hydrogen type stainless steel electrode. Direct current reverse welding can be carried out in all position welding. With excellent welding process performance, stable arc, less spatter, easy to remove slag, the deposited metal has excellent mechanical properties and crack resistance, low temperature resistance, good impact toughness.Usage: used for welding of carbon steel and low alloy steel structure important (compression and dynamic), such as 16Mn, 09Mn2Si, 09Mn2V, B, A and marine D, E grade steel, also used for welding carbon steel plate and poor weldability.Chemical composition of deposited metal (%)chemical compositionC = 0.12Mn = 1.60Si = 0.75S = 0.035P = 0.040Ni = 0.30Mo = 0.30Cr = 0.20V = 0.08Diffusible hydrogen content in deposited metal: 8.0ml/100g (glycerol)Reference current (DC+)Electrode diameter (mm)2.5.3.2.4.5.Welding current (A)60~10080~140110~210160~230Matters needing attention:The electrode is subject to 300~350 C 1H 1 before welding with baking, drying with.The welding must remove impurity welding rust, oil, water etc..3 be short arc welding operation, narrow welding bead.
No, the stainless steel electrode is also the beginning of the E
E5015 welding rod, also known as J507, J strip structure steel electrode. It belongs to low hydrogen sodium basic electrode. E stands for welding rod, and 50 represents tensile strength 50kgf/ mm215 represents low hydrogen and sodium type, suitable for all position welding of flat, horizontal, vertical and vertical positions. DC reverse welding is adopted.G507, the welding rod does not have this model.
