As well as the welding of various parts such as threaded plugs and sockets, accessories, couplings, turning parts, supports, saddles and fittings, Vogel Tube Bending can connect these products together by means of different soldering techniques. Since our foundation in 1951, Vogel Tube Bending has gained experience in the hard and soft soldering of various materials such as copper, steel, stainless steel, brass, zinc and aluminium.


Induction soldering

Vogel Tube Bending possesses ultra-modern induction soldering machines that were developed in collaboration with a German partner set up at the University of Berlin. The induction soldering process is ideal for connecting all electrically-conductive materials. No flame is used in this process. An inductor generates an alternating current in the part to be processed, without making contact with the product to be soldered. The soldering area is brought up to soldering temperature by this alternating current. With this process, work can be done at high temperatures so that rather than expensive silver alloys, cheaper copper alloys may be used. These copper alloys have a greater tensile strength so that a strong high quality connection is made. The soldering happens under a protective gas blanket so that no oxidation happens. Another advantage of this process is that no flux is needed. The cleaning, removal of flux and oxidised deposit on the connection are avoided and the product can be given a surface treatment without pickling and passivation.

Advantages of induction soldering are:

  • Suitable for large series
  • High degree of mechanisation and automation
  • Locally-restrained heat application
  • Short heat-up and cool-down times
  • Minor deformation of parts to be soldered
  • No oxidation after soldering
  • Metallically clean surface
  • No flux needed
  • Cheaper solder alloys
