Note: Braze an end plug on a stainless steel car grill

Objective:

Braze an end plug on a stainless steel car grill before powder coating application

End Product:

Stainless steel car grill

Equipment:

Ambrell 1 kW induction heating system, equipped with a remote workhead containing one 0.66 μF capacitor. An induction heating coil designed and developed specifically for this application. 

Materials:

Stainless steel car grill 0.5 inx 0.19 in (12.7mm x 4.8mm) end lugs braze ring 

Temperature:

1350 °F (732 °C)

Frequency:

267 kHz

Testing:

A three-turn square shaped helical coil is used to heat the end of the grill. End plugs are inserted into the grill and the assembly is inserted into the coil for 30 seconds. The braze flows to create a neat and clean leak-proof joint.

Benefits:

  • Rapid localized heat to joint area only

  • Minimized oxidation reduces cleaning time

  • Hands-free heating that involves no operator skill for manufacturing

  • Even distribution of heating
