Induction Brazing Carbide To Stainless Steel

Induction Brazing Carbide To Stainless Steel Shaft With IGBT Heating Units

Objective Brazing a cone shaped carbide to a stainless steel shaft for a digger
Material Cone shaped carbide 1.12โ€ (28.4mm) dia, 1.5โ€(38.1mm) tall,ย stainless steel shaft 1.12โ€ (28.4mm) dia and various length, blackย brazing flux and braze shims
Temperature 1500 ยบF (815 ยบC)
Frequency 277 kHz
Equipment โ€ข DW-UHF-10ย kW induction heating system, equipped with a remoteย workhead containing two 1.0ฮผF capacitors for a total of 0.5ฮผF
โ€ข An induction heating coil designed and developed specifically forย this application.
Process A three turn helical coil is used to braze the carbide to the shaft. Theย steel shaft is fluxed and the braze shim placed on top. The carbideย tip is fluxed and placed on top of the shim, lining up the countersunkย hole in the carbide. The hole is not fluxed because the flux outgasesย and causes the carbide to build up pressure and attempt to repelย from the shaft. Power is applied for 85 seconds for the braze shim toย flow and make a good joint.
DAWEIโ€™s customer has a customerย who is unhappy with the braze quality of their digger so ourย customer is looking for a better quality brazing process.ย DAWEIโ€™sย customer is very happy with the sample brazedย diggers and the help he received from the Ameritherm lab inย developing his brazing process.
Results/Benefits Induction heating provides:
โ€ข Rapid localized heating only where needed
โ€ข Creates clean, controllable joints
โ€ข Hands-free heating that involves no operator skill forย manufacturing
โ€ข Even distribution of heating

Brazing Carbide To Steel Shank

Brazing Carbide To Steel Shankย with Induction

Objective :Brazing carbide teeth to a steel jaw in less than 5 minutes
Material: Steel pipe jaw, 0.5โ€ (12.7mm) dia, 1.25โ€ (31.75mm) long, 0.25โ€(6.35mm) thick carbide teeth, black flux and silver copperย braze shims
Temperature: 1292ยบF (700ยบC)
Frequency: 300kHz
Equipment โ€ข DW-UHF-10kW induction heating system, equipped with aย remote workhead containing one 0.66ฮผF capacitor
โ€ข An induction heating coil designed and developedย specifically for this application.
Process: A two turn rectangular helical coil is used to heat the carbideย and steel to 1292ยบF (700ยบC) for 4 to 5 minutes. Three brazeย shims control the amount of braze and the even heat allows for
a good flow of braze creating an aesthetically pleasing bond.
Results/Benefits Induction heating provides:
โ€ข Hands-free heating that involves no operator skill forย manufacturing
โ€ข Consistent, repeatable aesthetically pleasing brazes
โ€ข Even distribution of heating

Induction Brazing Carbide

Induction Brazing Carbide File

Objective:ย Induction Brazing carbideย rotary file assemblies with uniform concentricity in an aerospace application

Material โ€ข Carbide blank โ€ข High speed steel shank โ€ข Temperature indicating paint โ€ข Braze shim and black flux

Temperature 1400ยฐF (760ยฐC)

Frequency 550 kHz

Equipment:ย DW-UHF-4.5kw induction heating system, equipped with a remote heat station containing two 0.33 ฮผF capacitors (total 0.66 ฮผF) An induction heating coil designed and developed specifically for this application.

Process A multi-turn helical coil is used. The part is heated to determine the time required to reach the desired temperature and required heat pattern. It takes approximately 30 – 45 seconds to reach 1400ยฐF (760ยฐC) depending on the various part sizes. Flux is applied to the entire part. A braze shim is sandwiched between the steel shank and carbide.ย Induction heating powerย is applied until the braze flows. With proper fixturing, concentricity of the part can be achieved.

Results/Benefits โ€ข Repeatable, consistent precise heat.
