Resistance spot welding is a resistance welding process in which coalescence of metal is produced at the faying surface by the heat generated at the joint because of contact resistance to the flow of electric current. Force is always applied before, during, and after the application of current to prevent arcing at the faying surfaces and to forge the weld metal during post heating. The process is used extensively for joining low and mild carbon steel sheet metal components for automobiles, cabinets, furniture, and similar products. Stainless

different tool edge radii from 2 to 62 μm and studied the effects of tool edge wear on cutting forces in Inconel 718. However, with advances in computational techniques, studies are now focused toward using numerical methods such as finite element method (FEM) for analysis. Krishnakumar et al . [ 3 ] studied the effects of residual stresses on AISI 4340 steel during multiple pass turning and the FE model was validated with the experimental results. Thepsonthi et al . [ 4 ] studied the effects of tool edge radius on the machining performance of end-milling process. Both

A cylindrical workpiece made of AISI 4340 steel with dimensions (∅50 mm × 120 mm) was selected for this study. AISI 4340 steel is a high tensile alloy steel with wear resistance properties and is extensively used in the automotive and general engineering applications, which include aircraft, propeller or gear shafts, connecting rods and aircraft landing gear components. The chemical composition and the mechanical properties of AISI 4340 steel are shown in Table 1 and Table 2 , respectively.

condenser. Investigation of failure was carried out by visual and dye penetration examination and by using various instruments by Mudali et al . [ 5 ] Wu et al . [ 6 ] developed a new condenser-evaporator by replacing the old one for a large scale air separation plant of capacity 30000 m 3 /hr. with oxygen as the output. Here, the author described the condenser-evaporator as Quasi-annular flow condenser-evaporator type by altering the boiling and condensation mechanism of heat transfer and found that the developed condenser-evaporator was more efficient in all respect

gets certain pressure rise. From there, it flows over guide vanes to the inlet of the next impeller, and from there, to discharge. A small part of the feed water, that is, 10% is taken from the space behind the last impeller for the operation of automatic balancing device to balance the hydraulic axial thrust of the pump rotor. Since the medium of the BFP is hot water, the operating temperature must be maintained in the pumps. Thermal equalizing lines are provided at both ends of the mechanical seals in order to meet this purpose. Vibration readings of the Boiler
FSW welding. There are two inverting positions in FSW welding for the base metal AA6063 placed in retreating side (RS), while AA5083 is placed in the advanced side (AS). The aluminum alloy of AA6063 is placed in the retreating side due to its lower tensile strength. A non-consumable rotating tool made of high speed steel (HSS) is shown in Figure 1(a) . The tool pin is a straight cylindrical profile with shoulder diameter of 20 mm, 5 mm pin diameter, 5 mm pin tip length and D/d ratio of 4. The friction stir welds using AA5083 and AA6063 aluminum alloys were
