- A welding operation is time-studied during which an operator was pace-rated as 120%. The operator took, on an average, 8 minutes for producing the weld-joint. If a total of 10% allowances are allowed for this operation. What is the expected standard production rate of the weld-joint in units per 8 hour day?what are the assumption made in the design of welded jointsWrite down the damage patterns that occur in the rivet joints that are forced axially. Explain how strength calculations are made under static stresses.
- 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 operationExplain how mechanical advantage relates to the power and speed of joint movement.Provide a reasonable explanation for the following observation: a welded component made of Al 6061-T6 alloy is routinely found to deform plastically first in the region adjacent to the weld joint despite the fact that the stress is nominally the same everywhere in the component. What solution would you propose to fix this problem, assuming that the weld joint cannot be eliminated from the design?
- Identify the conditions under which a brazed joint is likely to be “stronger” than the brazing material by itself. Describe the trends in joint fracture strength as it becomes wider/narrower or thinner/thicker.What do you understand by the term welded joint? How it differs from riveted joint?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.
