POWER TECHNOLOGIES Induction heating application notes for industry

Induction Heating Induction heating is an ingenious and effective, non-contact process for electromagnetically heating electrically conductive materials such as metals and semiconductors. Heat is transferred to the material by a rapidly fluctuating magnetic field, created by running a high-frequency alternating current through an electromagnet specially designed for the application. Induction heating is not only fast and efficient, but also provides a high-tech, precise heating technique.

Induction Brazing Steel to Wolfram Carbide Induction Braze Carbide Cap to Steel Shaft The goal is to braze steel to wolfram carbide in 5 seconds using flux and braze alloy. The objective of this application is to braze a cap to a steel shaft using induction. Customer currently uses a torch process, but would like to change to induction to reduce scrap and rework and improve the quality of the braze. Materials • Steel tool tail and wolfram carbide receiver • Silver soldering paste (PN:R0113) • Flux Key Parameters Temperature: Approximately 1440° F (780° C) 1. The assembly is positioned on...

Brazing Aluminum to Aluminum The objective of the application test is brazing aluminum to aluminum in less than 15 seconds. We have aluminum tubing and an aluminum “receiver”. The brazing alloy is an alloy ring, and has a flow temperature of 1030°F (554°C). 1. The aluminum component and aluminum tubing were assembled together with the alloy ring. Flux was added. The part was positioned in the induction coil. 2. Power was turned off after 14 seconds, and the process of brazing aluminum to aluminum was complete. 3. The aluminum tubing and aluminum component to be brazed, shown separately and...

The 3 completed samples shown. Key Parameters Temperature: Approximately 1450°F (788°C) Power: 1.5 kW Time: 21 seconds Application test objective is brazing carbide to steel, and confirm heating time. Customer provided samples of carbide tips of various sizes and shapes to be brazed to steel shanks of various sizes and shapes. Confirm...

Induction Brazing Alloy to Wire The goal of the test application is induction brazing alloy to wire, with the wire as short as possible. 1. Brazing flux is applied 3. The wire is positioned inside the coil Materials • Brazing paste (Easy-Flo 45) Key Parameters • Power: 2.4 kW • Time: 4 Seconds 2. Placing the brazing flux on the alloy 4. A closer view of the positioning inside the coil Equipment UPT-S5, Ultraheat 5 kW Power Supply HS-4 Heat Station Plate concentrated coil

Brazing with Ultraflex UBraze Handheld Brazing System 1. UBraze Handheld Brazing System with T Coil 2. UBraze is positioned at the joint. The customer needs to braze copper tubing to copper tubing using brazing alloy and flux. The copper tubing is in a variety of shapes, and is not always easily positioned using a traditional heat station. Therefore, the customer would like to utilize the Ultraflex UBraze Handheld Brazing System. There are no time restrictions. 3. UBraze heats the joint. Materials • Copper tubing • T Coil, to allow ideal positioning with copper tubing joints • Brazing rod •...

Induction Brazing Steel Tubing to Copper Tubing Brazing a Heat Exchanger The customer’s application is brazing a heat exchanger. There are “U” returns that are brazed to the receiving tubes on the heat exchanger. These returns are used to flow the water through the heat exchanger, and keep the unit cooled. Brazing tests were conducted with flux and without flux at the customer’s request. The current process is done with a torch. The goal is to braze steel tube to copper tube in 60 seconds using flux and braze alloy. Materials • Brazing preform • Brazing flux (Test 1 only) Materials • Steel...

Automated Induction Brazing of Copper Pipes in Refrigerator Assembly for In-Place Brazing Automated Brazing of Copper Pipes with Automatic Feeding of Brazing Wire Objective The objective is to automate the brazing of multiple joints on refrigerator pipes using induction heating. Equipment Dragon 15 – Robotic Brazing System Materials • Copper pipes size 0.236” x 0.0295” ( 6 x 0.75 mm) • Brazing rings – 0.0393” (1 mm) (CuP7) Process: The Dragon15 brazes multiple joints located in predefined positions in the assembly. Brazing alloy rings are placed on the joints prior to the brazing process....

Carbide Tipping Induction Brazing Using Handheld Brazing System Brazing Carbide Tips to Steel Impeller The objective of this application test is brazing carbide tips to a steep Impeller. Use induction heating to first debraze used carbide tips from the steel impeller, and then rebraze new replacement carbide tips. Customer is considering bringing the job in house in an effort to improve turn-around time and minimize downtime. Objective Induction brazing copper of copper: ½” copper tubing and copper fitting with brazing alloy and flux using the UBraze HandHeld Brazing System. Equipment...

Heating to Curing Temperature using Induction In this application test, we are heating to curing temperature using induction, to attach a speaker diaphragm to a speaker basket. The adhesive will be applied to the speaker basket, and the speaker diaphragm placed immediately above. The adhesive has an activation temperature of 134° F, or 57° C. The customer wants to use induction for heating the speaker basket to the curing temperature. This will activate the adhesive, and create the bond to the rubber speaker diaphragm. This application test will confirm that the speaker basket will heat to...
