Solution :-
Power of Weld = 12 * current Watts
Power required to weld = rho * C * ( Tmelt - Tambient) * A * weld speed
= 7860 * 460 * ( 1723 - 298 ) * 1.29 * 10^-5 * 0.02032 (0.8 in /s = 0.02032 m/s )
= 1350.5437 watts
current = 1350.5437 / 12 = 112.545 Amperes

Welding Problem A gas tungsten arc welding operation is used to create a fillet weld on both sides of a T-joint between two 1" thick medium carbon steel plates. The length of the T-joint is 36". The fillet weld as has a" legs. The welding operation will be carried out at a current 300 amps and a voltage of 20V. The welding process melts a volume of the parent material that is equal to 30% of the volume of the...

10- In a welding operation carried out on a eutectoid steel (C =0.8wt%), the selection of welding travel speed, applied voltage and current and application of blowing air and wrapping of the work piece into insulating cloth was as such that the following cooling schedules obtained. You are required to specify the most likely microstructure of the weld metal. Once identified the most likely microstructure, then discuss the ductility and toughness of the weld joint. Rc (Hardness) Eutectoid temperature Temperature...

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...

msu Q3. A high-speed proportional solenoid valve is shown in Figure 2.Avoltage proportional to the desired position of the spool is applied to the coil. The resulting magnetic field produced by the current in the coil causes the armature to move. A push pin connected to the armature moves the spool. A linear voltage differential transformer (LVDT) that outputs a voltage proportional to displacement senses the spool's position. This voltage can be used in a feedback path to implement closed-loop...

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...
