“…In recent years adoption of this technique in automotive industries has taken boom. [12] In survey of Poona industrial area it is observed that in number of auto parts it is absolute essential to join different metals to join these dissimilar metals is challenging work. Currently research on laser welding of dissimilar metal is on broad level.…”

“…With sound and deep weld and with high speed then those of others. Main response factor to join the dissimilar metals are solubility of different metals, wide difference in melting temperature [12], wide difference between reflectivity of the metal plate to be joined, excessive thermal conductivity of one of them or both metal plates or parts., wide differences in coefficient of thermal expansion. All these create variety of defects and imperfection in the joints.…”

Welding particularly joining dissimilar metals is new technology. Laser welding is a challenging task and most essential and reliable method of joining dissimilar metal used in various industrial area. Out of the modern welding laser welding is gaining its popularity due to its various unique features. Laser welding, is modern method of joining similar or dissimilar parts metal/non-metal by laser beam of very high power, high temperature source. Very good control on input factors, very small heat affected zone, precise accurate welding joint and high speed are some attractive features of this technique. This technology gives more flexibility to design engineer. Various kind of lasers such as Nd:YAG, Co2 laser, Diode laser, disk laser m/c are used in welding of automobile, aerospace and ships. All concept of laser welding depends on the key-hole phenomena. It is a cavity formed by recoil pressure and energy absorption is due to high temperature multi reflection of laser rays. So this gives deep Penetration of weld joint. This paper shows various Challanges of dissimilar metal welding and technique to over come this. In our use study We are going to use dissimilar metal plates of 3.5 mm thick of 16MnCr5 and 316 SS. This metal jonts are used in production of automotive cylindrical part in large quantity.
