Mild Steel Welding Rod Plant

Mild Steel Welding Rod Manufacturing Plant Introduction AWS E6013 (CB-J421) is a kind of carbon steel electrode with titania type coating. It is widely used on AC and DC in all positions and suitably for welding low-carbon steel structures, especially suitable for welding on thin plates and cosmetic weldig which requires the weld beads to be beautiful and glossy. Aws E7018 used for welding carbon steel and low-alloy steel strutures, such as 16Mn,etc. AWS E6011 suitable for butt welding ,fillet welding and lap welding on thin plates, such as low-carbon steel structures like flues of power stations, air ducts, transformer oil tanks, hulls, exterior panels of cars, etc.  Chemical composition of welding electrode (%) Item C Mn Si S P Ni Cr Mo V Standard Value ≤0.036 ≤0.037 ≤0.038 ≤0.039 ≤0.040 ≤0.030 ≤0.020 ≤0.030 ≤0.08 Sample Value 0.08 0.43 0.21 0.021 0.026 0.04 0.011 0.007 0.009  Mechanical properties of deposited metal (%) Item Tensile strength Rm (MPa) Yield Strength ReL (MPa) Elongation A (%) AKV impact Value °C J Standard value ≥430 ≥330 ≥16 0 ≥47 Sample value 490 396 26 0 85  Reference current (AC/DC) Rod diameter 2.0mm 2.5mm 3.2mm 4.0mm 5.0mm welding current (A) 40-70 70-110 100-150 160-210 200-260 Packing 2.5*300mm 2.5kgs/inner box, 8inner box/carton=20kgs;  Ctn Size: 32*18*16cm 3.2*350mm 5.0kgs/inner box, 4inner box/carton=20kgs;
