Welding Electrodes is composed of two parts, the coating and the core. The melting speed of the coating and the core should be uniform, and the melting speed should be slower than the melting speed of the core. Welding Rods has different diameters and lengths, and the diameter of the electrode is generally selected according to the thickness of the component during use. Commonly used electrode diameters are as Φ1.6, Φ2.0, Φ2.5, Φ3.2, Φ4.0, Φ5.0 Chrome-Molybdenum Welding Electrodes is a graphite type surfacing electrode, the surfacing metal is molybdenum chromium boron alloy, the hardness of the surfacing layer is HRC=60~65°, and the matrix is Cr7Mo6B8 dispersion hardening and toughening austenite. Tungsten Carbide Tube Welding Rod Electrode is eutectic or near-eutectic alloy, the electrode not only has high temperature resistance (up to 650 ℃) but also wear resistance, toughness and crack resistance. Has high resistance to impact abrasive wear. Cast Tungsten Carbide Tube Welding Rod is suitable for surfacing welding of wear-resistant parts in various industries such as steel mills, power plants, cement plants, casting plants, building materials plants, etc…Its welding life is 6~8 times higher than that of other materials
