(a) Conclude the Electron Beam Machining (EBM) and Laser Beam Machining (LBM).

"Your boss requests a recommendation on which process to use to make fillet welds on stainless steel rail tank cars with this material. Your heart beating fast, you respond. " A: Use HYPERFILL®. The cooling rate is acceptable for this material and productivity gains are important given the large size of the product. B: "Use HYPERFILL®, for the same reasons as (A), BUT we need to change materials to a low carbon stainless steel (e.g. 304L) or we will get corrosion failure in the HAZ." C: "Use GMAW-P. For this material, this heat input is best. " D: "Use GMAW-P, for the same reasons as (C), but we need to change materials to a low carbon stainless steel (e.g. 304L) or we will get corrosion failure in the FZ."

Please solve a & b

What are shape functions in FEM? What properties do the shape functions have?

a) Explain the functions of a plastic coatings. b) Assume you are a Mechanical engineer working in Al Jazeera Steel Company LLC is situated in Sohar. You are assigned a task to setup the system to coat the surface of the hot component dipped in oil. For example the dark blue colour steel gun is shown below. Based on the above scenario, answer the following questicns. i) Suggest the suitable surface coating process. ii) Explain the above surface coating process in detail.

Carburizing is the process where: -manganese contributes to the strengthening of the material -the part is quenched in a bath of oil to decrease distorion -carbon is added to the outer layer of a steel part through absorbtion and diffusion. -a part is packed in a salt bath to increase durability
