What is induction welding?

What is induction welding?
With induction welding the heat is electromagneticallyĀ induced in the workpiece. The speed and accuracy
of induction welding make it ideal for edge welding ofĀ tubes and pipes. In this process, pipes pass an inductionĀ coil at high speed. As they do so, their edges areĀ heated then squeezed together to form a longitudinalĀ weld seam. Induction welding is particularly suitableĀ for high-volume production. Induction welders canĀ also be fitted with contact heads, turning them into
dual purpose welding systems.
What are the benefits?
Automated induction longitudinal welding is a reliable,Ā high-throughput process. The low power consumptionĀ and high efficiency of DAWEIĀ Induction welding systemsĀ reduce costs. Their controllability and repeatability minimizeĀ scrap. Our systems are also flexibleā€”automaticĀ load matching ensures full output power across a wideĀ range of tube sizes. And their small footprints makeĀ them easy to integrate or retrofit into production lines.
Where is it used?
Induction welding is used in the tube and pipe industryĀ for the longitudinal welding of stainless steel (magneticĀ and non-magnetic), aluminum, low-carbon and highstrengthĀ low-alloy (HSLA) steels and many other conductive
materials.

Induction Preheating Welding Steel Pipe

Induction Preheating Welding Steel Pipe With High Frequency Heating System

Objective To preheat a steel pipe to 500ĀŗF (260ĀŗC) before welding.
Material Steel shaft assembly 5ā€ to 8ā€ OD (127-203.2mm) with a 2ā€Ā (50.8mm) heat zone.
Temperature 500ĀŗF (260ĀŗC), if higher temperatures are required, heat timeĀ can be increased.
Frequency 60 kHz
Equipment ā€¢ DW-HF-60kW induction heating system, equipped with aĀ remote workhead containing eight 1.0 Ī¼F capacitors for aĀ total of 8 Ī¼F.
ā€¢ An induction heating coil designed and developedĀ specifically for this application.
Process A multi-turn two position channel ā€œCā€ coil, adjustable on aĀ busbar is used to heat the desired heat zone. The coil isĀ adjustable to fit various diameter pipes. The shaft is rotated inĀ a fixture and heated for 3 minutes to achieve a temperature ofĀ 500ĀŗF (260ĀŗC).
Results/Benefits Induction heating provides:
ā€¢ Preheating prevents shock to shaft which eliminatesĀ cracking in the welding phase.
ā€¢ Hands-free heating that involves no operator skill forĀ manufacturing.
ā€¢ Even distribution of heating between the shank and the Ā sleeve.
