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.
