1. Quality issues with brazing, such as the presence of sand, microcracks, and other defects in the brazing area.
2. Poor control of the size of the gap between brazed seams, and insufficient use of brazing material during welding, resulting in insufficient welding force and causing incomplete fusion, thus affecting the effectiveness of use.
3. Selection issues with brazing materials. Typically, two types of brazing materials, copper and silver, are used. Under normal circumstances, as long as the strict process is followed, both types of brazing materials can meet the production requirements of cemented carbide tips. However, the use of brazing materials that do not meet quality requirements will inevitably affect the brazing effect.
The cemented carbide tips produced by SKYMECH use imported brazing flux and materials.
The computer precisely controls the transfer speed and welding temperature of each cemented carbide tip to ensure that each tip has a full and defect-free brazing with copper, without any flaws or bubbles. Additionally, each tip is adequately heated both internally and externally to reach the required quenching temperature. They are then automatically placed into the quenching tank by a fully automated robotic arm. The quenching liquid’s raw materials, concentration ratio, and quenching time have been determined as the optimal solution through extensive and repeated experiments conducted by our technical staff.
