How does diamond segment quality affect welding and ways of welding?
Normally, internal defects of diamond segments don’t affect welding while external defects like irregular curve, broken mould, black spots and asymmetric shape may have a considerable effect on welding, because they may lead to asymmetry, instability, hard segment opening and big saw kerf.
Different welding methods for different stones
Welding methods vary depending on diamond segment formula and body.
1. Normally, marble cutting segments require soft body, so electric current and heating temperature should be reduced at the time of welding; instant heating should be avoided, and power-off protection time should be lengthened. Longer power-off protection time is also required during reheating. (This applies to welding on silent saw blank)
2. Though granite cutting segments are hard, reheating method is also required for welding to increase the strength.
