Introduction to diamond bit welding tools

Diamond's diamond segment welding process with the development of science and technology is constantly developing, in the early years, in the mine, most of the use of fire welding to complete the welding of the diamond segment, in this process, the tool selected is extremely important, because most of the alignment, cleaning work needs to use the right tools, fire welding needs to be the tools are:

1: Oxygen cylinder and spray gun: The knife bit is quickly heated by the spray gun, and the flux or solder that fixes the old bit is quickly melted and removed. In addition to the rejection effect, during the welding process, the new solder or flux is quickly melted, so that the tool head can be welded quickly and conveniently. In the process of fire welding, oxygen cylinders and welding torches are essential tools, and the most common welding method of early stone saw blades, but because this method requires a high degree of quantity of welders, it is gradually in the phase of elimination, especially in recent years, the portability of high-frequency welding machines has continued to improve, coupled with the continuous reduction of prices, so that high-frequency welding has slowly become the mainstream welding method.



Here are some non-flame welding tools that can be widely used in all bit product welding:

2: Tungsten steel pliers (or manganese steel pliers), the substrate of the saw blade can often be reused, so it is very necessary to replace the diamond segment, how to replace the diamond segment? First of all, the need to heat the bit, when the temperature rises to a certain extent, the solder connecting the bit and the blade melts, at this time, the temperature of the bit is also very high, to remove the bit of the knife, you need to withstand the high temperature of the pliers, so the use of tungsten steel pliers or manganese steel pliers can quickly remove the bit. In addition to these two common pliers, other high-temperature resistant metal pliers are also available, and it should be noted that it is necessary to choose a metal with low thermal conductivity as much as possible, otherwise it is easy to have excessive thermal conductivity and burns.

3: Manganese steel shovel, high temperature of the head of the removal process, we will find that there are some solder will appear in the process of high temperature flow material, and will produce some solid compounds, these compounds will lead to the saw blade matrix of the serrated surface uneven situation, so, the use of high temperature resistant manganese steel shovel to remove the metal part is a very important operation, of course, how to have a better tungsten steel shovel will be better, it is worth noting that in the process of bit heating, tungsten steel pliers and manganese steel shovel together with the use of welding efficiency.

4: Fixture, if the use of automatic or semi-automatic welding machine, there will be equipped with a good fixture for people to use, but if it is fire welding, you need to make a welding fixture yourself, this fixture is composed of a pressure head fixed at the top of the bit and fixed on both sides of the cutter head, in the welding process, first put the solder in the middle of the bit and the saw blade, by rapidly heating the diamond segment, to ensure that the blade horizontal buckle plate remains in a plane with the saw blade, and finally through cooling, complete the final welding, and the automatic welding machine, Most of them are fixed by the indenter at the top without the need for a side clamp, which is not much different, and is for better and faster welding.



5: In addition to the fixture, it is the corrective pliers, also known as welding strength detection tongs, mainly used to pull the diamond segment after welding, if you can easily let the diamond segment off the saw blade, then you need to re-weld the saw blade.

6: For the medium diameter saw blade, there are saw blade flatness detectors, end jump detectors, and diameter jump detectors, which can help the diamond segment to be better welded on the saw blade.
