Induction Brazing of Hydraulic Fittings Case Study

13th July 2020

Inductelec systems are used in the production of hydraulic assemblies used particularly in large scale, construction machinery. Induction brazing is the ideal technique for joining steel parts where welding is not suitable. A well-designed induction brazed steel joint provides many benefits including part geometry integrity and lower part stress. Steel typically has a high resistivity - therefore it couples well to induction energy and heats easily. However, the thermal conductivity is usually low so the induction brazing of steel parts should not be rushed. With steel, it is important the heat is given time to soak through to the joint surface for proper flow and wetting out of the braze material.

What are the Benefits?

  • Energy efficiency
  • Accurate and repeatable delivery of heat
  • Uniform heat giving predictable brazed joints
  • Precise control of cycle times ensuring minimal scale formation
  • Minimised heat times for each component size
  • Temperature control is accurate with precise control of ramp-up times and holding temperatures
  • Data logging giving the output parameters of every component produced
  • Fewer reject parts as all aspects of the process can be monitored
  • Ease of integration into an existing production cell
  • Improved quality
  • Only narrowly defined areas are heated, leaving adjacent areas and materials unaffected
  • Correctly brazed joints are strong, leak-proof and corrosion resistant
  • Joints are very neat, usually requiring no further milling, grinding or finishing
