Tungsten carbide tiles welding method for hard alloy and steel, belonging to In the field of welding technology. Including the following steps: A. Hard Preheat the alloy block to 500 ℃~800 ℃, and preheat the steel to 200 ℃~400 ℃, preheat the welding rod to 100 ℃~300 ℃; B. Using welding rods for welding hard alloy blocks and steel Perform electric welding and slowly place it in lime powder or insulation box after welding Cool to room temperature. Easy to use, with a wide range of applications, including Beneficial for improving the strength of welded joints between hard alloys and steel based metals Degree and temperature resistance, suitable for mining machinery and subway tunnel shields The excavation head of the construction machine, geological drilling bit, rock drill.Hard alloy welding on tools such as construction machinery and shovel teeth
Tungsten carbide tiles is a high productivity tool material that combines high melting point and high hardness metal carbide powder with adhesive Mix the binder and use powder metallurgy to press various required shapes of workpieces. The welding of hard alloys and steel mainly involves Cutting tools, cutting tools, molds, mining tools, and various parts with wear resistance as the main performance for mechanical processing The characteristic of components is that they can save a large amount of precious metals, reduce production costs, and improve the service life of components. Hard alloy tools have been widely used in various industrial sectors and have achieved significant results.
