1. The structure of the welded cutting tool should have sufficient rigidity. The sufficient rigidity is guaranteed by the maximum allowable external dimensions, as well as the use of high-strength steel grades and heat treatment.
2. Carbide inserts should be firmly fixed. Carbide welding inserts should have sufficient fixation reliability. It is guaranteed by the kerf and welding quality. Therefore, the shape of the insert groove should be selected according to the shape of the blade and the geometric parameters of the tool.
3. Carefully check the blade. Before welding the blade to the blade, it is necessary to check the blade and the blade. First, check that the supporting surface of the blade cannot be seriously bent. There should be no serious carburized layer on the cemented carbide welding surface, and at the same time The dirt on the surface of the carbide insert and the insert groove of the shank should also be removed to ensure reliable welding.
4. Reasonable selection of solder In order to ensure the welding strength, appropriate solder should be selected. During the welding process, good wettability and fluidity should be ensured, and air bubbles should be excluded, so that the welding and the alloy welding surface are fully contacted, and there is no lack of welding.
5. It is recommended to use industrial borax for the correct selection of welding flux. Before use, it should be dehydrated in a drying furnace, then crushed, sieved to remove mechanical debris, and set aside.
