Solved in 2 steps
- Can a tee weld be strong if the welds on both sides do not have deep penetration? Why or why not?A gas tungsten arc welding operation is performed using a current 520 A and arc voltage of 30 V at a welding speed 5 mm/s. Assuming that the arc efficiency is 70 %. Determine the net heat input per unit length of the weld.A fas tungsten arc welding operation is performed using a current 300 A and arc voltage of 25 V at a welding speed 10 mm/s. Assuming that the arc efficiency is 60%. Determine the net heat input per unit length of the weld.
- It is desired to determine the cost of the submerged arc welding operation in the preceding problem, including electric power cost but excluding work material costs. Power during arc-on time = 9,000 W, and cost of electricity = $0.15/kWH. The labor cost rate = $33.00/hr and the SAW equipment cost = $20.00/hr (including applicable overheads). The cost of each spool of electrode wire = $50.00. The cost of granular flux used in each cycle = $2.00. What is the welding cost of each completed tube?A continuous fillet wild is used to weld two pieces of 7.0-mm-thick austenitic stainless steel plate in an arc-welding operation. The plates are joined at a 90° angle using an inside fillet corner joint. The velocity of the welding head is 6 mm/sec. Assume the cross section of the weld bead approximates a right angle isosceles triangle (a right triangle with the two legs and their corresponding angles equal) with a leg length of 4.5 mm. The length of the weld = 230 mm. The melting factor of the setup = 0.65, the heat transfer factor = 0.90, and the Tm for austenitic stainless steel = 1670°K. Determine (a) The amount of heat (in joules) required to melt the volume of metal in (b) The heat that , (c) The rate of heat generation required at the welding source to accomplish the weld this weld (filler metal plus base metal) must be generated at the heat sourceA 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.
- A resistance spot-welding operation is performed on two pieces of 1.5 mm thick sheet steel using 12000 amps current for a duration of 0.20 second. The electrodes are 6 mm in diameter at the contacting surfaces. Resistance is assumed to be 0.0001 ohms and the resulting weld nugget is 6 mm in diameter and 2.5 mm thick. The unit melting energy for the metal is 12 Jmm³. What portion of heat generated was used to form the weld?A gas tungsten arc welding operation is performed using a current of 250 A and an arc voltage of 20 V at a welding speed of 5 mm/s. Assuming that the arc efficiency is 70%, the net heat input per unit length of the weld will be kJ/mm (round off to one decimal place).A shielded metal arc-welding operation is performed on low carbon steel (Tm=1760 K) plates at a voltage = 25 volts and a current = 200 amps. The heat transfer factor = 0.90, and the melting factor = 0.75. Find (a) rate of heat generation at the weld and (b) volume rate of metal welded
