Note: Heat the end of catalytic converter for weld testing

Objective:

Heat the end of lorry catalytic converter exhaust system. The assembly must be held at target temperature for 200 hours, whilst the assembly is vibrated to test the weld strength.

End Product:

Catalytic converter

Equipment:

Ambrell 5 kW, induction heating system, equipped with a remote work head containing two 5 μF capacitors for a total of 10 μF and an induction heating coil designed and developed specifically for this application. 

Materials:

Steel

Temperature:

842-932 °F (450-500 °C)

Frequency:

75 kHz

Testing:

A four-turn conical-shaped solenoid coil is used to heat the end of the exhaust system during the weld strength testing. It takes approximately 5 minutes to reach the target temperature between 842-932 °F (450-500 °C). This temperature is then held for 200 hours whilst the system is vibrated to simulate driving conditions. The weld is then inspected for cracks.

Benefits:

Precision output of the power supply holds the desired temperature within a tight tolerance.
