Scope

Main technical content: This document specifies the basic requirements for induction brazing of aluminum tubes and stainless steel tubes, the selection of brazing alloys and fluxes, brazing equipment and parameters, brazing process, quality requirements, common brazing defects and solutions, etc. This document is applicable to the induction brazing process and quality control of aluminum tubes and stainless steel tubes. Table 2 shows the specific process parameters: workpiece diameter/cm, coil diameter, power/kW, brazing time/s, and other parameters. For example, when the workpiece diameter is 4-10 cm, the coil diameter is 3-5 cm, the power is 15-18 kW, the brazing time is 20-25 s, and the workpiece diameter is 10-30 cm, the coil diameter is 35-45 cm, and the power is 30-30 kW, the brazing time is 18-25 s, and the coil diameter is 25-35 cm.
