Defect-free laser welding of ferrous and non-ferrous alloys

Since hybrid vehicles’ (HV) usage (2 million cars on road today, by 2020 it will hit as 4 million) is becoming more popular today, transportation industries have focused their thrust to make HV as much as energy efficient with cost effectiveness. HV is made of number of complex components/parts (body, motors, generators, batteries, brakes, control systems). Moreover, parts/components of HV are made with different combination of materials such as metals, ceramics, plastics, etc. (see below figure). In this, using laser for fabrication of these components is an elegant route for achieving industrial goals which is impossible by conventional means (ultrasonic, resistance, etc.). Multiple laser heads installed in controllable (closed-loop) processing environment to provide multi-functionality (welding, brazing, soldering, heat treatment) with defect-free components (pores, holes, blowout, etc.) as cost-effectively.
