The tubes welding is performed under direct induction heating, when using ABL and indirect, when using PBL.
The generator is supplied with two types of inductors:
-- linear inductor with effective length less than 230mm, used for longitudinal welding (1) of tubes or for tube filling machines (3). Up to 3 tubes can be welded cross cut at one and the same time in the tube filling machines.
-- inductor for front welding of a tube's shoulder (2) with maximum tube diameter50mm. There are modifications for round and elipse shoulder of the tube.
The generators are applicable for induction heating in other areas, too, but for each separate purpose, there have to be designed suitable equipment and devices for coordination, depending on the requirements and the type of the parts, that have to be heated.
