A GTAW operation is performed on low carbon steel, whose unit melting energy is 10.3 J/mm3. The welding voltage is 22 volts and the current is 135 amps. The heat transfer factor is 0.7 and the melting factor is 0.65. If filler metal wire of 3.5 mm diameter is added to the operation, the final weld bead is composed of 60% volume of filler and 40% volume base metal. If the travel speed in the operation is 5 mm/sec, determine (a) cross-sectional area of the weld bead, and (b) the feed rate (mm/sec) at which the filler wire must be supplied.
The welding parameters to be used to butt weld a metal alloy are being evaluated. In order to set up the welding machine, the melting factor for the metal (f2) has to be determined. The welding machine can deliver 4000 watts of power and the heat transfer factor for the welding process (f1) is 0.9. The final weld bead consists of 8 0% filler metal and 40% parent metal. The melting temperature of the filler metal and the parent metal is the same 2540 deg F. The cross-sectional area of the weld bead is 0.5 sq inches. The rate at which filler metal is added to the weld is 1 cu inch per min. Conversion factor 1 Btu = 1055 J and 0 deg F = 460 deg R Calculate the melting factor.
It has been reported that gas–tungsten arc welds of aluminum made in the overhead position (assumed lap weld joint) tend to have a significantly higher porosity level than those made in the flat position: a. Explain why b. Sketch the general view of the overhead position c. Indicate where the (most probable) location of the porosity
What is staircase effect? A welding operation on an aluminum alloy makes a groove weld.The cross-sectional area of the weld is 30.0 mm2. The welding velocity is 4.0 mm/sec. Theheat transfer factor is [0.92+{AAA/(20+YY)}] and the melting factor is [0.48+{AAA/(20+YY)}], where AAA are the last three digits and YY are the first two digits of yourstudent ID. The melting temperature of the aluminum alloy is 667°C. Determine the rate ofheat generation required at the welding source.
The unit melting energy for a certain sheet metal is 10J/mm^3 .The thickness of each of the two sheets to be spot-welded is = mm. To achive required strength, it is desired to form a weldnugget that is =7 mm in diameter and 3.5 mm thick. The weld duration will be set at 44 sec .If the electrical resistance between the two surfaces is 144 micro-ohms and only one half the electricity generated will be used to form the weld nugget Determine the minium current level required in this operation
Calculate the heat input during the arc welding process, if the voltage is 33 volts, current is 115 amperes, the length of the weld is 88mm and the time to complete the weld 34 secs.
Select an appropriate weld technique and joint design for welding 150mm of thick material.
An RSW operation is used to join two pieces of sheet steel having a unit melting energy of 8369.85 J/cm3. The sheet steel has a thickness of 0.3125 cm. The weld duration will be set at 0.25 sec with a current of 11,000 amp. Based on the electrode diameter, the weld nugget will have a diameter of 0.75 cm. Experience has shown that 40% of the supplied heat melts the nugget and the rest is dissipated by the metal. If the electrical resistance between the surfaces is 130 micro-ohms, what is the thickness of the weld nugget assuming it has a uniform thickness?
Can a tee weld be strong if the welds on both sides do not have deep penetration? Why or why not?
During arc welding, the heat input per unit length reduces, with increase of
please send handwritten solution for Q13 part a
The below Figure Q1 shows an aluminium alloy sheet metal requires to be spot welded. In order for the weld to achieve its required strength, it has to be 2mm thick and the weld duration will be set at 0.3 sec. If it is assumed that the electrical resistance between the surfaces is 160 micro-ohms, and that only 40% of the electrical energy generated will be used to form the weld nugget (the rest being dissipated into the work), determine: a) The heat energy generated at the source b) The minimum current level required in this operation c) Assuming the heat transfer factor is 0.9, what would the melting factor be? d) The power density of the process, and comment on the value.
