D106 surfacing electrode Description: D106 is a low hydrogen potassium type coating ordinary manganese welding electrodes, AC and DC, AC load voltage space is greater than 70V. Uses: Used to weld or repair of low carbon steel, carbon steel and low alloy steel wear parts of the surface, such as axles, gears and mixer blades. Deposited metal chemical composition (%) Chemical Composition C Mn Guaranteed value ≤0.20 ≤3.50 surfacing layer hardness: HB≥220 Reference current (AC, DC +) electrode diameter (mm) φ3.2 φ4.0 φ5.0 Welding current ( A) 90 ~ 110 140 ~ 180 180 ~ 220 Note: 1. 300-350 ℃ before welding electrodes shall be baked 1h. 2. In large parts before welding should be preheated to about 200 ℃, and the welding surface portion of the rust and oil cleaned.
