In the process of high-frequency welding diamond segment, the high-frequency welding machine melts the solder by quickly increasing the temperature of the heating zone, so that the melted welding blade can quickly connect and fix the substrate and the knife head, under this working principle, the following problems need to be solved:

1): High frequency welding machine power selection

2): Selection of solder tabs and solder 

3): What preparations should be made before high-frequency welding

4): High frequency welding process with detailed steps

5): Inspection after the saw blade is welded

Here are some of the questions we answered one by one, and there are many tips to explain:

1: The choice of high frequency welding machine power:

The mechanical price of high-frequency welding machine is not high, and the welding machine with different brands of power from about 2500-8000 on the market has a certain impact, such as 15KW, 25KW, 35KW, 60KW, etc., but generally in the process of selection, the choice of 15KW power will be more, because such machinery, the price is cheaper, but in the actual application process, the higher the welding machine will have a certain impact on the welding strength of the diamond knife head, especially the high-frequency welding power to 35KW machinery, The impact resistance of the welded bit and the stability of the bit are 5-10 percent higher, and in terms of efficiency, it is also much higher than the efficiency of the 15KW welding machine, so if you want to engage in the knife head welding business, you want to weld more quickly, and choose a welding machine with higher power is a better choice.

2: Selection of solder tabs and solder

If you weld an iron-based tool head, you can choose a brazed electrode or a silver copper solder bit, but if you weld a cobalt-based bit or a copper-based bit, then the choice of silver pad and silver copper solder disc with a higher silver content is a more suitable choice. In terms of solder, if the solder is uncertain, it is very important to add solder paste to assist in the welding process.

3: What preparations should be made before high-frequency welding?

First of all, if it is a small and medium-sized saw blade, because the width of the saw blade is narrow, the width of the knife bit is also small, it is easy to drop the knife head, so you can brush a layer of flux on the base part and the bottom of the bit in advance, and then put a welding blade on top of the flux, so that the tool head welding process can be completed quickly and smoothly.

Secondly, before the tool head is welded, the residue of the upper part of the diamond blade should be thoroughly cleaned, especially the flux and the tool head.

Again, if you use a semi-automatic welding machine, you need to cut the welding wire or solder blade, or buy a fixed specification of the welding blade.

Finally, some marble bits should be aligned in the direction of their cutting edges before welding.

4: High frequency welding process and detailed steps the flip-over method and the partition welding method have been applied very maturely, and the most important point is that it is necessary to use the tool head locator to perform better positioning during the welding process.

5: Inspection after the saw blade is welded After the saw blade is welded, the flatness of the saw blade needs to be tested, and a detailed test of its stationary end jump and stationary diameter jump is also required, and if the data is normal, such a saw blade can be used.
