Diamond Segment for Volcanic Edge Cutting

1. Segment used on Diameter 250-600mm blades, mostly cutting 2-5cm slabs or tiles.

2. Segment designs in Narrow Radial (NR), Wide Radial (WR) and Split Radial(SR).

3. Selected quality diamond and metal bond used for fast cutting and good edge finish.

Diamond Segment For Volcanic Edge Cutting：

Applications:

This volcanic stone edge cutting diamond segments works as a function part of volcanic diamond saw blade to cut lava stone edges on manual cutting machine, table saw or bridge saw. It consists of synthetic diamond, Cobalt powder and various of metal powder in soft to hard bonds as per stone hardness. This volcanic edge cutting diamond segments is with aggressive diamond particles inside for fast cutting purpose.

Analysis of the occurrence and cause of the "bubbling" phenomenon in the weld
This situation often occurs when the diamond segment is welded, especially when brazing the layer diamond segment without the welding transition layer. The specific manifestation is that during the process of melting and filling the weld seam, the bubbles around the edge of the weld seam continue to burst and blow up, showing a slow boiling state, and a large amount of gas is gushing out of the weld seam, and the liquid solder and viscous flux blow up a large number of bubbles, which will burst after they grow to a certain extent. The "bubbling" phenomenon does not stop until the molten solder has completely solidified.
The welding seam bubbling directly causes a large number of pores around the welding seam. The pores are large and small, and the edges of the welding seam are alternately distributed. It seriously affects the welding strength. In order to prove that the welding strength is affected, we reheated the segment and then removed it, and observed the welding surface. The solder on the welding surface of the base body was normal, however, the welding surface of the blade leaves some obvious traces of squeezing the solder due to gas expansion, and the blade does not form an effective connection with the saw blade base. During the use of such a saw blade, the blade easily loses segment.
In addition, water vapor and a large amount of other media can enter the weld seam along the pores, corrode the welded surface, and gradually reduce the connection strength. Therefore, measures must be taken to prevent the "bubbling" phenomenon.
