Joining precision parts without melting the base material.
This time, I would like to introduce examples of joining using silver solder. There are various methods for joining metals, such as gas welding, arc welding, laser welding, and electron beam welding, all of which involve melting the base material to join them. On the other hand, in the case of brazing, a filler material with a lower melting point than the base material is melted to join the parts, allowing for the joining of complex shapes or precision parts without melting the base material. Additionally, with metallization treatment, it is also possible to join metals and ceramics. The common method for melting the filler material is using a gas burner, but high-frequency induction heating or heating furnaces may also be used, and the optimal method is chosen based on the size, shape, and quantity of the parts to be joined. I am looking forward to trying various materials in the future. Furthermore, I can offer proposals that include not only joining but also shape processing, so please feel free to consult with me. ■ Cross-sectional images Cu + Cu (Copper + Copper) W + Cu (Tungsten + Copper) Mo + Cu (Molybdenum + Copper) Mo + Mo (Molybdenum + Molybdenum)
