What is the diamond segment welding technique?
There are three methods to weld and braze diamond segments onto the saw blade: silver brazed diamond blade, wholly sintered diamond blade and laser welded diamond blade.Silver brazed diamond blade: diamond segments are brazed to the steel saw base using a silver solder. Silver brazed diamond blade can only be used in wet cuttings. If they are used in dry cuttings, the silver solder may melt under the high temperature generated in the dry cutting and the segments can break from the steel core and be extremely dangerous.
Wholly sintered diamond blade: the diamond blade is made by putting the steel core together with the diamond segments and the metal bond materials into a mold and then sintering them in a sintering machine.
Laser welded diamond blade: the laser melts the diamond segment and the steel core creating a stronger weld, which can hold the diamond segments even in high temperatures, so laser welded diamond blades can be used to cut many types of materials without water cooling.
