Induction brazing units
The iew Induktive Erwärmungsanlagen GmbH is able to adapt induction brazing systems exactly to the required customer needs.
In this case, complex brazing applications can be realized with the help of our PLC sequence control, for example, clamping and fixing of the component, automatic feeding of the brazing wire, lowering a glass cover to supply the inert gas, pre- and afterflooding of shielding gas, defining the heating-, holding- and cooling time, etc. Below are some examples of our brazing systems.

This workplace has been constructed for the inductive brazing of carbide metals as well as PCD-, PCBN-, and CBN tools.
Thereby, the operator inserts the single components into the brazing device and moves them into a closed, respectively open inductor. The herein described workplace was naturally equipped with a temperature control (infrared-pyrometer) to prevent possible thermal damage (graphitization) of the diamond. Of course, this brazing device can also be equipped with a protection gas unit.
For this special customer order we also integrated a shower to simultaneously harden the workpiece. In combination with the infrared pyrometer, the PLC initializes a hardening shower after the brazing filler metal reaches the solidus temperature. However, this hardening process cannot be compared to regular hardening processes (Hardening normally at approx. 1000 °C / Brazing in this case 700 °C) but nontheless leads to an increased hardness of the workpiece.» See product
This assembly is a manual brazing workplace for the soldering of honing tools utilizing a soldering alloy.
The single components of the honing tool are placed within the soldering device with an inductor especially designed for this application. Moreover, this soldering device also consists of a temperature control ensuring an accurate temperature gradiation, ultimately leading to a consistent tool quality. Via the integrated cooling device (air cooling), the liquidus phase of the solder during cooling can be minimized. If needed, this assembly can naturally be equipped with a shielding gas unit.
The utilization of honing tools often describes the last production process of a fine machining treatment and can be applied to nearly every material. It is the goal to positively influence the dimensional accuracy, thus minimizing the frictional resistance.» See product
This assembly is a semiautomatic brazing workplace for the inductive brazing of saw teeth onto chain links.
Thereby, a staff member assembles a product carrier with 10 chain links, adds the saw teeth together with the brazing foil and finally fixes them in a retainer jaw. After closing the fixation, the carrier plate is positioned behind a manually lockable safety glass. The following brazing process starts automatically and the 10 brazing joints are clocked one after another, utilitzing a carriage system and an open fork inductor. The completion of the brazing process is followed by an acoustic signal.
The assembly naturally features a PLC as well as a contact-free temperature measuring system (infrared-pyrometer). The carrier plate comes up with an integrated water cooling system to ensure stable brazing conditions.» See product
This brazing workplace has been equipped with a protection gas unit and has been designed for the inductive brazing of stainless steel tubes and turned/milled parts in the shape of T- and pipe fittings.
The operator manually inserts the single components and activates a clamping tool via a two hand activator. The brazing assembly naturally comes with a RFID component identification. This ensures that the customer specific brazing program is chosen and all product-dependent parameters regarding the protection gas unit are initialized. Preparation- and type errors can thereby be eliminated. The brazing assembly has been designed for a five-day working week in a three shift working pattern for 30.000 parts a year with 2 brazing joints each. The PLC interface always displays the current brazing process and supervises every single assembly step. Furthermore, the corresponding temperature profile is graphically displayed. The brazing parameters are saved within a loc-file (Name of operator, temperatur profile, maximum temperature, amount of protection gas, etc.).
The device was designed in a way that allows an alteration of the product line. To achieve this, only the customer specific product carries has to be altered. Thereby, the operation of the IBU115 is warranted for years.» See product
This induction round table was especially developed for the brazing of ball-type nipples onto stainless steel tubes with protective gas.
The operational procedure can be summarized as follows: A staff member inserts a new assembly group with an already mounted ball-type nipple. The ball-type nipple is brazed onto the steel tube during the first cycle, automatically rotated by 180° and then completed, after the staff member mounted the second ball-type nipple with a copper brazing preform. There are always two steel tubes infront of the operator, one for the first and one for the second brazing joint. The induction round table consists of 12 double stations.
Furthermore, the brazing assembly is equipped with a system that automatically discharges steel tubes that do not meet the prior defined brazing parameters. This prevents that n.i.o. parts are further processed. This induction round table can realise more than 2.5 million brazing joints per year.» See product
Die ML1000 wurde speziell für das Ein- und Auslöten von Hartmetallschneiden auf einen Sägeblatt-Trägerstahl entwickelt und konstruiert. Das Haupteinsatzgebiet ist dabei der Sägewerksektor.
Die Hartmetallschneide wird hierbei nach dem Einlegen in Position gebracht und sodann mit dem Sägeblatt-Trägerstahl stoffschlüssig verlötet. Das Sägeblatt wird nach jeder Lötung manuell weitergedreht, erneut in Position gebracht und mit einer Hartmetallschneide bestückt. Das dazugehörige Pyrometer in Kombination mit einer SPS-Ablaufsteuerung (Menüführung in deutsch und englisch) ermöglicht eine optimale Temperaturkontrolle und Reproduzierbarkeit.
Die Temperaturregelung kann auch für Folgeprogramme genutzt werden: Beispielsweise wird im ersten Schritt bei ca. 750°C gelötet und bei Erreichen einer vordefinierten Abkühltemperatur von ungefähr 300°C wird automatisch ein zweites Programm für das Anlassen des Lötbereiches auf z.B. 450°C gestartet.» See product
The IBU220 was especially designed for brazing and hardening processes in the research and development.
This workplace consists of two 20kW generators and the corresponding heating station with pre-assembled inductors and an electric lifting system with 300mm traverse way. Due to the desired flexibility in the research and development, this assembly has not been outfitted with a set equipment, instead it can be altered depending on the test series. This device has also been equipped with a protection gas unit. Since this device also features a PLC, both induction units can be triggered separately. Additionally, successive heating processes can be realised (Brazing unit 1 done -> Automatic start of brazing unit 2 and vice versa).
This leads to the highest possible flexibility regarding the heat treatment.» See product
