- Workpieces are selectively melted and thus joined together.
- Ideally, filler metal always has the same melting temperature as the workpiece itself (in brazing, a brazing alloy is always used which has a lower melting temperature than the workpiece). Risks due to “postflow” of solder are thus avoided.
- No annealing of the material – so even mechanics and thin sheets can be worked on without affecting the strength.
- No difference in color or hardness
