It is very flexible on how thick of materials it can work with. Additionally, it is very portable because it only requires a generator for power. “Finally, it’s quite versatile because it can weld many different types of metals, including cast iron, steel, nickel and aluminum” (“Welding”). In other welding processes you must use a shielding gas to protect the weld zone from the surrounding atmosphere. When using shielded
“Stud welding is a complete one-step fastening system, using a wide variety of fasteners called weld studs” (Stud Welding Equipment 1). Stud welding is a very easy process to use, it’s even easier than a MIG welder because all it takes is the pull of a trigger to release the weld stud. Stud welding is used in children’s toys, appliances, construction, offshore, and much more. Stud welding is a less expensive process than other fastening methods and can be used in locations which do not allow the use of other fasteners (Stud Welding Equipment 1).
Die castings are made from the following non-ferrous metals - Aluminum - Copper - Zinc - Magnesium - Lead - Tin based alloys Advantages of Die casting: Die casting is an efficient, economical process offering a broader range of shapes and components than any other manufacturing processes. Parts produced from die casting have longer service life and may be designed to visual appeal of the surrounding part. Manufacturing designers can gain number of advantages and benefits to the company by specifying die cast parts. High speed production – die casting provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required and lakhs of identical castings can be produced before additional tooling is required.
• Ease of Installation The installation of metal tiles is a much easier process than the construction of plastered ceilings. They are lighter and they can be attached to the ceilings faster. The process of installing these tiles can be completed in very little time. • They hide imperfections: They are ideal for covering plastic ceiling that are in need of
The excellent wear resistance of D-type cold-work tool steels is the result of their high chromium (~12wt.%) and high carbon (1.5 to 2.35wt.%) contents. Generally, the high-carbon, high-alloy tool steels are particularly difficult to process by the conventional ingot metallurgy route. The main challenge is that the relatively slow cooling of the conventional static cast ingot allows the formation of coarse eutectic carbide structures, which are difficult to break down during hot working [1, ]. For overcoming these problems some new processing methods such as powder metallurgy (PM) and spray forming have been developed for production of the most highly alloyed tool steels, such as high-carbon, high-chromium (AISI D series) and high-speed (AISI T and M series) [1, , , ]. These techniques offer the possibility to produce steels with higher homogeneity, lack of segregations, finer microstructure and uniform d... ... middle of paper ... ...

This is implemented by using dsPIC for controlling the drive, as it provides higher efficiency and lower operating costs, (i.e.,) it reduces the cost of drive components. Key words: AC Induction Motor, SVPWM, dsPIC I.INTROUCTION The AC induction motor (ACIM) is the workhorse of industrial and residential motor applications due to its simple construction and durability. These motors have no brushes to wear out or magnets to add to the cost. The rotor assembly is a simple steel cage. ACIM’s are designed to operate at a constant input voltage and frequency, but you can effectively control an ACIM in an open loop variable speed application if the frequency of the motor input voltage is varied.
Naval brass which is the alloy of copper has high hardness when compared to all other alloys of copper. It has high electrical resistance, high strength and high corrosion resistance when compared to other alloy of copper. So, it is difficult to fusion welding of copper and naval brass. The major problem of these alloys in fusion welding is the evaporation of zinc during the welding process. At the end of welding, the welded metal becomes
