MF9254 ADVANCES IN CASTING AND WELDING PROCESSES L T P C 3 0 0 3
AIM: To impart knowledge on basic concepts and advances in casting and welding processes.
OBJECTIVES:
To study the metallurgical concepts and applications of casting and welding process.
To acquire knowledge in CAD of casting and automation of welding process.
UNIT I CASTING DESIGN 8
Heat transfer between metal and mould –– Design considerations in casting – Designing for directional solidification and minimum stresses - principles and design of gating and risering
UNIT II CASTING METALLURGY 8
Solidification of pure metal and alloys – shrinkage in cast metals – progressive and directional solidification –– Degasification of the melt-casting defects – Castability of steel , Cast Iron, Al alloys , Babbit alloy and Cu alloy.
UNIT III RECENT TRENDS IN CASTING AND FOUNDRY LAYOUT 8
Shell moulding, precision investment casting, CO2 moulding, centrifugal casting, Die casting, Continuous casting, Counter gravity low pressure casting, Squeeze casting and semisolid processes. Layout of mechanized foundry – sand reclamation – material handling in foundry pollution control in foundry –– Computer aided design of casting.
UNIT IV WELDING METALLURGY AND DESIGN 10
Heat affected Zone and its characteristics – Weldability of steels, cast iron, stainless steel, aluminum, Mg , Cu , Zirconium and titanium alloys – Carbon Equivalent of Plain and alloy steels Hydrogen embrittlement – Lamellar tearing – Residual stress – Distortion and its control . Heat transfer and solidification - Analysis of stresses in welded structures – pre and post welding heat treatments – weld joint design – welding defects
– Testing of weldment.
UNIT V RECENT TRENDS IN WELDING 11
Friction welding, friction stir welding – explosive welding – diffusion bonding – high frequency induction welding – ultrasonic welding – electron beam welding – Laser beam welding –Plasma welding – Electroslag welding- narrow gap, hybrid twin wire active TIG – Tandem MIG- modern brazing and soldering techniques – induction, dip resistance, diffusion processes – Hot gas, wave and vapour phase soldering. Overview of
automation of welding in aerospace, nuclear, surface transport vehicles and under water welding.
