The aim of this Research to investigate the effect of variation in brazing parameters like clearance gap between base plates, scarf angle and soaking temperature on mechanical properties of brazed joint of Al 6061 plates. Brazing method used for investigation is torch (flame) brazing with oxy-LPG flame and Zn-18Al flux cored filler wire. Brazed joint tested for tensile strength and hardness. Multi-objective optimization was carried out. Results indicate that Clearance gap, scarf angle and soaking temperature have a significant effect on tensile strength, Hardness of joint and filler material consumption. Among Clearance gap, Scarf angle and Soaking temperature, the effect of scarf angle and clearance gap are more dominant. Values of tensile strength and hardness of joint are almost same as parent base material. Parameters that provides maximum tensile strength are Clearance gap 0.183 mm, scarf angle 57.18o and soaking temperature 250.87oC. Parameters that provides minimum hardness are clearance gap 0.298, scarf angle 85.67oC and soaking temperature 296.33oC. Parameters that provides maximum tensile strength, minimum hardness and minimum filler material consumption are Clearance gap 0.216 mm, scarf angle 63.79o and soaking temperature 294.35oC. These numerical optimization is carried out by software Design Expert Version 12.
