Keywords:
Resistance brazing, Shear strength, Design of experimentsAbstract
This research aims to study on influence of resistance brazing parameters on brazed joint between 316L stainless steel plates. Sil CD1050-5M filler metal was used in joining form lap joint. The experimental design of 24 full factorial design with 2 replicates was employed, and the factors of interest included welding current, welding time, electrode pressure and holding time. Results showed that the main effects were welding current, welding time, electrode pressure and 2-way interactions between welding current and electrode pressure significantly affect to the shear strength of brazed joint at α = 0.05. In addition, the brazed joint with welding current of 4,000 A, welding time of 2 s and electrode pressure of 0.3 MPa provided the maximum shear strength.
