The induction heating technique allows the welding of small and large-sized mechanical parts, with the most diversified shapes and with various material couplings (steel, copper, brass, aluminium, etc.). The heating speed combined with the possibility to localise the heat only in the area to be welded make induction, compared to other systems, involve minimal joint oxidation and deformation. By acting on three essential parameters of the induction system (distributed power, working frequency and heating time) ideal conditions for correct braze welding are achieved.
There are several applications of induction welding, among which:
ATE designs, manufactures and commissions the production of Plants and Systems for induction welding of stainless steel pots bases.
Welding can be carried out with the use of a soldering alloy (BRAZE WELDING) or without, by hot pressing the parts (PRESS WELDING).
Welding systems generally consist of press welding and braze welding stations. They are usually equipped with modern manipulators to quickly move pots between stations, loading systems, conveyor belts and other systems required by the customer.
The manufacturing solutions for this type of system are varied and more or less complex.
Press welding systems allow excellent temperature distribution on aluminium discs, on oval shapes and on austenitic or ferritic steel disc covers, thanks to the sequential heating of a series of inductors. In this case, the most used solution to heat the pots takes place on one side (the upper one) with evident manufacturing simplicity of the rotary table that has the function of moving the parts. The inductors are usually designed with a multiple-power outlet with the possibility to heat a multitude of pot sizes with a single type of inductor, established during the design phase and equipped with simple and quick adjustment systems for their centering and replacement.
