When using a grinding wheel to grind tungsten electrodes, the following points should be noted:
Choose the right grinding wheel material
Use special hard abrasive grinding wheels, such as silicon carbide or diamond grinding wheels, and avoid using ordinary sandpaper or soft grinding wheels to prevent contamination or cracks on the electrode surface during the grinding process.
Control the speed of the grinding wheel
The rotation speed of the grinding wheel should not be too high to avoid the local temperature of the tungsten electrode rising due to friction and overheating, which will cause material structure changes or brittle cracks.
Keep the grinding even
During grinding, the tungsten electrode should be rotated gently and evenly along the electrode axis to ensure that the end face is flat and the sharp corners are symmetrical, so as to avoid electrode deflection caused by excessive wear on one side.
Prevents overheating and sparks
Avoid long-term continuous grinding, intermittent operation or proper cooling to prevent the electrode from burning or discoloration due to excessive temperature, and keep the electrode performance stable.
Clean environment
The grinding environment should be kept clean to avoid grinding wheel debris, oil stains and other impurities from adhering to the electrode surface and affecting the welding performance.
Safety
Operators should wear safety goggles, protective gloves, and masks to prevent wheel splashing debris and dust damage.
Check the grinding wheel regularly
The grinding wheel should be trimmed and replaced regularly to ensure grinding efficiency and surface quality, and avoid uneven or clogged surfaces affecting the grinding effect.
