The vacuum brazing process is under the condition of vacuum heating, the melting point of the brazing material is lower than that of the base alloy, and the molten brazing material under the capillary suction of the small gap of the workpiece to be welded fills the gap of the base metal to form a solid combination of the brazing material. Due to the low temperature of vacuum brazing heating, it has little effect on the physical and chemical properties of the base metal, and several welds of complex parts can be welded at one time, so it is highly valued by the aviation, aerospace and electronics industries.

China's marine steel plate efficient CNC plasma arc cutting equipment currently relies on imports, and when importing such equipment, as the key wearing parts in the equipment, the plasma arc cutting electrode must be purchased as an accessory at the same time, which is expensive. The plasma arc cutting electrode consists of an oxygen-free copper matrix, a silver inner ring, and a tantalum wire. Hot pressing combined quality directly affects the service life of plasma arc cutting electrodes.

Last year, we were entrusted with the research and process tests on silver brazing of plasma arc cutting electrode assemblies. (1) Vacuum brazing equipment Plasma arc cutting electrode process test When selecting equipment, we fully consider that preventing the graphite heating element and graphite screen from depositing carbon under high temperature, and graphite heat insulation screen-absorption and deflation are more serious than metal screens, etc. The U.S. pressurized high-rate vacuum quench furnace has laid the foundation for scale production. (2) Selection of brazing materials Plasma arc cutting electrodes require good electrical conductivity and high part accuracy, and must strictly control deformation. The correct selection of solder is an important factor to ensure the quality of plasma arc cutting electrodes.

1: when the charcoal fire just lit, you should not barbecue immediately, do not think that the fire is very hot event works, directly with open fire barbecue food, will produce a variety of harmful substances to human body, will bake the food black, this point we should pay attention to later.

2,Do not eat too much meat when eating barbecue, should properly eat some vegetables, fruits, meat is very indigestible food, if the stomach is full of meat, it will increase the difficulty of digestion, serious will cause permanent damage to the stomach, the next time to eat barbecue should pay attention to it.

3: when using barbecue grill wire mesh to bake food, do not dip too much seasoning, seasoning too much will have a bad effect on the body, too much seasoning also leads to food taste distortion, resulting in unable to taste the original food, and everything tastes the same , then you can try barbecue next time.
