A diamond blade is produced through a two-step process. The initial phase involves designing and manufacturing the core, during which the steel is shaped and refined to ensure the resulting diamond blades are of superior quality and possess longevity. The subsequent step entails welding the segments onto the actual core of the diamond blade.

Advantages and disadvantages of laser welding diamond saw blades compared with other saw blades

Advantages

- the depth and width of the weld area is large.

- the weld is extremely accurate, so the blade core is very minimally affected.

- laser welded can withstand higher temperatures during cutting and extending blade life significantly.

- The most important point is that the diamond segments would not drop during cutting.

Disadvantage

The disadvantage of laser welding diamond blade is that the diamond segments can not be replaced like high frequency welding blades when they are used up, and thus the cores are wasted.

Laser-welded diamond blades are utilized in the construction industry, particularly for concrete cutting tasks. In some cases, the concrete being cut contains steel bars. When cutting through these steel-reinforced sections within the concrete, the temperature of the diamond segments increases rapidly. This escalation in temperature can result in the detachment of the diamond blade segments, posing a significant hazard to the operators involved.

How to distinguish laser welding diamond saw blades with other blades?

The laser welding process with diamond blades fires the segments onto the core. This leaves the bond much stronger and produces a much better quality product. To distinguish laser welded diamond blades from other blades, look at where the blade meets the core. The weld seam of a laser welded blade looks much rougher than a pressed sintered blade. See the pictures below to help you distinguish.

How to distinguish sintered diamond saw blades from Electroplated blades:

Sintered blades often have a more solid and substantial appearance due to the densely bonded diamond and metal matrix. They are designed for heavy-duty cutting, such as in construction and masonry work. Electroplated blades, on the other hand, tend to look thinner with a layer of diamonds visibly attached to the cutting edge. These are typically used for intricate cutting in industries like jewelry making, electronics, and hobbies.
