- 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: Explain why Sketch the general view of the overhead position Indicate where the (most probable) location of the porosityDynamic forces F1 = 4000N and F2 = 6000N are applied to the welded part shown in the figure as shown below. For dynamic forces, both dynamics are synchronized, and when the force in the y-axis direction is downward, it is on the right in the x-axis direction. When the force is up, the other force is on the left. The welded part is made of 1018 HR steel, 10 mm thick. a) Safety factor for welding? b) Calculate the safety factor for the base metal. (Electrode type for question is E9010.)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?
- 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.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 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
- A U-groove weld is used to butt weld 2 pieces of 7.0-mm-thick titanium plate. The U-groove is prepared using a milling cutter so the radius of the groove is 3.0 mm. During welding, the penetration of the weld causes an additional 1.5 mm of material to be melted. The final cross-sectional area of the weld can be approximated by a semicircle with a radius of 4.5 mm. The length of the weld is 200 mm. The melting factor of the setup is 0.57 and the heat transfer factor is 0.86. (a) What is the quantity of heat (in Joules) required to melt the volume of metal in this weld (filler metal plus base metal)? Assume the resulting top surface of the weld bead is flush with the top surface of the plates. (b) What is the required heat generated at the welding source?Assume that two 1.5-mm thick steel sheets are being spot welded at a current of 4000 A and current-flow time is 0.3 s. Using electrodes 5 mm in diameter, estimate the amount of heat generated and the amount of heat required to melt the weld nugget. Use an effective resistance of 350 un. Take u= 9,7 Joule/mm Which one of the following are correct? O a. If the electrodes were 7 mm diameter, the amount of heat generated would decrease b. The amount of heat generated by the equipment is between 1600 to 1700 Joules c. The equipment has enough power to weld the steel sheets. d. The equipment does not have enough power to weld the steel sheets e. The amount of heat required is between 700 and 750 JoulesWhat does liquid-solid phase bonding mean and in which cases is it preferred over welding? What does capillarity mean in this process?
