5 An inexperienced welder has welded a structural beam together and cooled it rapidly under water. This has caused the grain structure to become brittle. The beam will be used in the construction of a building. Which heat treatment method would be best to make the weld suitable for its purpose? (A) Heat the weld to 700 degrees Celsius and allow to cool slowly. (B) Heat to around 600-650 and hold for an hour then allow to cool slowly. (C) Heating to 300 degrees Celsius and let cool. (D) Reheat the weld to below the austenitic range and quench under water. einsog Nirw b9zU

HANDWRITTEN ANSWER PLS. What does liquid-solid phase bonding mean and in which cases is it preferred instead of welding? What does capillarity mean in this process?
When steel is joined using arc welding, only the liquid fusion zone must be protected by a gas or flux. However, when titanium is welded, both the front and back sides of the welded metal must be protected. Why must these extra pre-cautions be taken when joining titanium?

A gas tungsten arc welding operation is performed using a current 500 A and arc voltage of 20 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.
11.16 Two 20-mm steel plates are butt-welded together. Both the plate and the welding electrode materials correspond to strength properties of Su = 500 MPa and S, = 400 MPa. The imposed loading fluctuates rapidly between -20 and +60 kN. Estimate the length of weld required in order to provide a safety factor of 2.5: (a) If the weld reinforcement is not removed. (b) If the excess weld material is carefully ground off to provide smooth, continu- ous surfaces.
Your boss requests a recommendation on which process to use to weld the high strength structural steel rail tank cars hull section. You have this additional information: P-GMAW Productivity is substantially lower. However, you have welders already qualified to do manual p-GMAW welding. Labor is 80% of total cost HYPERFILLⓇ® Productivity gains are important, and the volume of the product is sufficient on the rail tank cars to justify capital investment. With confidence, you respond: Use process because .(Give process and short explanation for why you want to use that process)
