Wear-resistant welding electrode: the use of carbon steel as the core of the low sodium hydrogen type coating tungsten carbide surfacing welding electrode, relying on the coating carbide alloy transition, surfacing metal tungsten content of 40-50%, because the coating is thicker, so the long sleeve during the welding process, the coating is red after the easy small pieces fall off, so it is appropriate to use dc reverse connection, use a small current.

Notice for Tungsten Welding Rod:

1. The electrode shall be baked at 300-350℃ for 1h before welding.

2. When the surfacing part is carbon steel, the preheating temperature is above 300℃; when the surfacing part is low-alloy steel, the preheating temperature is 400-500℃; when the surfacing part is stainless steel, the preheating temperature is 600-650℃.

3. Low-alloy steel and stainless steel shall be annealed at 700℃ after welding.
