What is induction welding?

What is induction welding?
With induction welding the heat is electromagneticallyย induced in the workpiece. The speed and accuracy
of induction welding make it ideal for edge welding ofย tubes and pipes. In this process, pipes pass an inductionย coil at high speed. As they do so, their edges areย heated then squeezed together to form a longitudinalย weld seam. Induction welding is particularly suitableย for high-volume production. Induction welders canย also be fitted with contact heads, turning them into
dual purpose welding systems.
What are the benefits?
Automated induction longitudinal welding is a reliable,ย high-throughput process. The low power consumptionย and high efficiency of DAWEIย Induction welding systemsย reduce costs. Their controllability and repeatability minimizeย scrap. Our systems are also flexibleโ€”automaticย load matching ensures full output power across a wideย range of tube sizes. And their small footprints makeย them easy to integrate or retrofit into production lines.
Where is it used?
Induction welding is used in the tube and pipe industryย for the longitudinal welding of stainless steel (magneticย and non-magnetic), aluminum, low-carbon and highstrengthย 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 500ยบF (260ยบC) before welding.
Material Steel shaft assembly 5โ€ to 8โ€ OD (127-203.2mm) with a 2โ€ย (50.8mm) heat zone.
Temperature 500ยบF (260ยบC), if higher temperatures are required, heat timeย can be increased.
Frequency 60 kHz
Equipment โ€ข DW-HF-60kW induction heating system, equipped with aย remote workhead containing eight 1.0 ฮผF capacitors for aย total of 8 ฮผF.
โ€ข An induction heating coil designed and developedย specifically for this application.
Process A multi-turn two position channel โ€œCโ€ coil, adjustable on aย busbar is used to heat the desired heat zone. The coil isย adjustable to fit various diameter pipes. The shaft is rotated inย a fixture and heated for 3 minutes to achieve a temperature ofย 500ยบF (260ยบC).
Results/Benefits Induction heating provides:
โ€ข Preheating prevents shock to shaft which eliminatesย cracking in the welding phase.
โ€ข Hands-free heating that involves no operator skill forย manufacturing.
โ€ข Even distribution of heating between the shank and the ย sleeve.
