“…The main reason is of joint is bad edge preparation. [30] For edge preparation we have option of mechanical cutting ( milling ) , surface grinding with coolant , shear cutting , wire cutting EDM , laser cutting and water jet cutting . We preferred water jet cutting for the edge preparation due to no heat effected zone with good accuracy good surface finish, low cost and fast method of cutting.…”

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.

“…Edge preparation may affect the properties of the material and weld formed [18] [12]. There are many ways of edge preparation such as boring, cutting and grinding [14]. There are two main features of edge preparation which influence the fatigue performance of a weld joint a) Cleanliness of faying surface b) Cutting of faying surface of base metal to be welded by fusion arc welding process.…”

This paper is a description of an alternative fixture for the edge preparation of elbows and pipes before welding. The welding will not penetrate the cross section of the pipe if the thickness of the pipes is more than eight millimeter, so edge preparation is done before welding. Fixtures are used to hold the pipes during the process of edge preparation. This paper deals with two major issues from the design of previous fixtures.Requirement of manual handling of the part.Precise rotations are not possible. The fixtures being used currently require more setting up time and they require manual handling to machine the other side. This paper describes a fixture which can reduce manual handling and be able to rotate the elbow either manually or using a motor.
