What is the Difference between Laser Welding and High Frequency Welding of Diamond Saw Blade?
In the diamond tool industry, Marble Saw Blade Diamond Cutting tools are mainly produced by sintering, high frequency welding and laser welding.
Compared with laser welding, high frequency welding has the following advantages:
1. Low equipment input, about 70000 RMB for each equipment;
2. The equipment is small and easy to handle (it can be operated on the construction site);
3. Easy to operate and maintain;
4. In high frequency welding, because there is a silver solder pad between the diamond segment and the matrix as the filler, the requirements for the radian of the diamond segment are not very strict;
5.The price of high frequency welding piece is low (take φ 350mm as an example, the lowest price is 90rmb), which is convenient for customers to accept.
Laser welding of Diamond Saw Blade for Marble Stone has the following characteristics:
1. Large equipment investment and large volume;
2. The operation of the equipment is simple, but the requirements for daily maintenance are high;
3. In general, special matrix (30CrMo for laser welding and 65Mn for high frequency welding) is required for laser welding of diamond saw blade;
4. Due to the fact that there is no filler between the diamond segment and the matrix, and the diameter of the laser beam is small, the requirements for the radian of the diamond segment in the manufacturing process are strict;
5. The price of laser welding saw blade is more expensive (take φ 350mm saw blade as an example, 30CrMo saw blade is 8 RMB more expensive than 65Mn saw blade) due to the factors of equipment depreciation, Beige Marble Multi Blade Diamond Block Segment production (mainly including arc grinding and non working layer production) and matrix price (take φ 350mm saw blade as an example, generally 170 RMB or higher);
6. High efficiency of laser welding (for example, the number of laser welding pieces is more than 200, while the number of high-frequency welding pieces is more than 20 in the case of welding φ 350mm saw blades in an 8-hour shift);
7. The biggest advantage of laser welding is that there is no tooth dropping in the process of dry cutting.
