The Most Important Technical Parameters For PCD Tool Welding


2023-05-12


In order to improve the grinding efficiency of PCD tools, most PCD tool manufacturers at home and abroad choose high-frequency welding technology when producing PCD tools. The most important technical parameters include welding temperature, welding time, heat preservation environment and heat preservation time. Now Demina company will introduce the importance of welding technology to PCD tools.

The welding temperature will directly affect the internal structure of the PCD cutting edge. If the welding temperature is too high, it will lead to the carbonization of PCD cutting edge and affect its cutting performance. If the welding temperature is too low, it will lead to weak welding and affect the joint strength.


Important Technical Parameters For PCD Tool Welding

Welding time refers to the time to maintain the welding temperature if the holding time is not enough, the flux is difficult to fully and evenly melt, which will also cause the phenomenon of welding instability. If the insulation time is too long, the PCD cutting edge will be exposed to high temperatures for a long time and affect its cutting performance. If the welded PCD tool is placed in the air to cool down, the welding will be unstable due to the excessive thermal stress between PCD and the tool body. In serious cases, cracks may even appear on the PCD tool. Therefore, it is best to quickly put the welded tool into a vacuum or inert gas medium at a certain temperature for a certain time, so that it slowly cool.

Beijing Demina can provide a vacuum welding machine for PCD tool manufacturers. They can also provide the grinding machines for PCD tool manufacturers. Welcome to visit our web site for more information.
