I want to know what materials I need to weld a carbide-tipped tool
If there are conditions, the use of liquefied petroleum gas and liquefied gas welding torch, because of the high liquid gas containing hydrogen, welding is not easy oxidation, black, and low flame temperature, alloy tool bit soft and uniform temperature rise, it is not easy to crack. Apply the pole to the grinding wheel, the metal luster, ground level, easy welding. First heated the cutter bar, 700 degrees (just a dark red) and a few borax, continue to heat and copper wire, copper wire at this time of melt, evenly spread out on the welding of the copper, not too thick, laying copper flat, otherwise the cutting head is bad. Leave the torch and sprinkle a little bit of borax. Use tweezers put good, the alloy tool bit heating cutter and cutter bar juncture place, this place is on the tool holder, (part) is not on the tip of this is for the sake of tool holder and tool bit heated at the same time, when the tool holder and tool bit reaches 800 degrees Fahrenheit, put the copper electrode, then copper electrode melt into the cutting head and the crevice tool rod, heat the torch around the cutting head shaking more, until the cutting head and the cutter bar to isothermal, cutting head completely floating on the cutter bar, welding is complete. Do not move at this time of tool holder, cutting head is out, wait about 15 seconds, copper sludge, the cutter and cutter bar in a heat insulation barrels containing vermiculite, slow cooling after about 4 hours, the temperature of the cooling to be able to use.
Brazing welder with brazing, the material is copper wire and welder, the method is very simple and my unit welds in this way.
A set of oxygen acetylene tools Brass welding rod A bottle of copper solder Alloy knife and shank material Goggles a pay Adjust the pressure, point the fire, adjust the flame, heat the workpiece (the alloy is placed in the position of the blade), and then the solder is added to the temperature.
You need to use the alloy electrode and 唖 welding tool Objects will first heated to red state (temperature of about 800 ~ 1000 degrees) and electrode with borax as flux (add) in accordance with the necessary then cemented carbide and tungsten steel lathe tool welding on the tool holder to complete a turning lathe turning tool rack can be attached cutting machine processing work
It is simple to use copper welding to pay attention to the relationship between the weight of the heating and the temperature and the heating time
