Welding-Brazing processes


INTRODUCTION

The brazing exploits fully the advantages of the Induction Heating. Indeed, abolishing exhaust gases and flames, improves the environment.

Welding is a process that joins materials, usually metals or thermoplastics, by causing fusion. In addition to melting the base metal, a filler material is often added to the joint to form a pool of molten material (the weld pool) that cools to form such a joint.

Brazing is a metal-joining process in which different metal parts are joined together by melting. A filler metal (having a lower melting point than the adjoining metal) is flowing into the joint and realize the union.

THE PROCESS

In induction heating, usually ferrous materials are heated rapidly from the electromagnetic field that is created by the alternating current applied from an induction coil that heat locally.

Brazing Solution An example of our solutions for brazing.

The filling material is added automatically in the right quantity, at the right moment.

ADVANTAGES OF INDUCTION HEATING

Furthermore, the extreme accuracy of heating managed by microprocessor, guarantees the quality of metallurgy and the Repeatability of process, while the high efficiency of Energy Transferring, it guarantees money savings.

  • Selective heating :
    Induction heating can be targeted to provide heat to very small areas within tight production tolerances. This advantage becomes particularly important with high-temperature brazing processes.
  • Better quality joints :
    Induction heating produces clean, leak proof joints by preventing the filler from flowing in areas that it shouldn’t flow.
  • Reduced oxidation and cleaning :
    without Flame, less oxidation and carbon build up on the parts.
  • Fast heating cycles :
    induction heating cycle is very short, more parts can be processed in the same amount of time, and less heat is released to the surrounding environment.
  • Consistent results:
    Induction brazing is an high quality process because it is a easily repeatable process. Time, temperature, alloy, fixturing, and part positioning are controllable.
