A welding operation will take place on carbon steel. The desired welding speed is around 0.8 in./s. If an arc welding power supply is used with a voltage of 120 V, what current is needed if the weld width is to be 0.2 in? Assume that the weld cross-section is triangular.

A resistance spot-welding operation performs a series of spot welds between two parts of sheet steel that are each 1/8 in thick. The steel has a unit melting energy = 130 Btu/in3. Weld duration is set at 0.25 sec, and current = 11,000 amp. The weld nugget has a diameter = 0.30 in. Experience has shown that 50% of the supplied heat melts the nugget, and the rest is dissipated. If the electrical resistance between the surfaces is 125 micro-ohms,...

For the oxyacetylene welding process, assume that the energy of the gas (the combination of oxygen and acetylene) combustion will be 0.05 J/mm3 at its stored pressure. For welding two pieces of bronze with a butt joint design, how much gas is required if the efficiency of the process is 50%? Assume that the workpieces are tubes with 25 mm outside diameter and the cross-section of the weld is designed to be 5 mm2. The specific energy required to melt...

CODE 102_8 Welding Many welding processes require the application of heat and/or pressure to produce a suitable bond between the two parts being joined. There are a number of conventional and commercially practiced welding processes, which possess limitations in relation to material type and thickness, and in addition, the cost analysis may not allow for a process to be used on a specific application. The selection of suitable welding consumable (electrode or wire) is also an important factor in producing...

Question 1 A turning operation is carried out on aluminum. Based on the specific energy values in Table 20.2, determine material removal rate and cutting power in the operation under the following sets of cutting conditions: (a) Cutting speed 5.6 m/s, feed 0.25 mm/rev, and depth of cut 2.0 mm; and (b) cutting speed- 1.3 m/s, feed 0.75 mm/rev, and depth 4.0 mm. Question 2 Consider a turning operation performed on steel whose hardness 225 HB at a cutting speed...

The piston's steel skirt is much more rigid than the aluminum skirt in smaller deformation and allowing for designs with tighter clearances tin harmful exhaust emissions) from the piston. This design has been shown to reduce piston termn results in a more stable piston with less oil consumption (thus further r which are machined prior to welding. The process...
