Induction Brazing Stainless Steel

Induction Brazing Stainless Steel Objective 1st Application: Braze hub assembly to needle holder 2nd Application: Braze Large tube to ring joint Material: 1st Application: Steel hub assembly and needle 0.1" dia(2.5mm) 2nd Application: Steel tube 1" OD (25.4 mm) and ring Temperature 1400 ºF (760 ºC) Frequency 325 kHz for brazing the needle 0.1" dia (2.5mm) 259 kHz for brazing ring to steel tube 1" OD (25.4 mm) Equipment • DW-UHF-4.5KW induction heating system, equipped with a remote workhead containing two .66 μF capacitors for a total of 1.32 μF • Two induction heating coils, designed and developed specifically for this dual application. Process 1st application: A two-turn helical coil is used to heat the hub assembly on the needle holder for 10 seconds. The coil concentrates the heat on the hub only, as the needle is magnetic and the hub material is non-magnetic. A small diameter braze wire is used to supply sufficient amount of braze creating a strong aesthetically pleasing bond. 2nd application: A three-turn helical coil is used for brazing the large tube to the ring joint for 3-5 minutes. A braze ring is used to supply sufficient amount of braze to create an aesthetically pleasing bond. Results/Benefits Induction heating provides: • Even distribution of heating, provides even flow of braze alloy for an aesthetically pleasing bond • System flexibility allows for the same unit to be used for two different applications which is a cost saving. https://dw-inductionheater.com/induction-brazing-stainless-steel.html?feed_id=250808&_unique_id=6675de8883b88

Induction Brazing Stainless Steel

Induction Brazing Stainless Steel Car grill  Objective Braze an end plug on a stainless steel car grill before powder coating application Material Stainless steel car grill 0.5” x 0.19” (12.7mm x 4.8mm), end plugs and braze ring Temperature: 1350 ºF (732°C) Frequency:400 kHz Equipment •DW-UHF-6kW-III induction heating system, equipped with a remote workhead containing one 0.66μF capacitor. • An induction heating coil designed and developed specifically for this application. Process 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. Results/Benefits Induction heating provides: • 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 https://dw-inductionheater.com/induction-brazing-stainless-steel-car-grill.html?feed_id=250303&_unique_id=6670df1a69964
