"Your boss requests a recommendation on which process to use to make fillet welds on stainless steel rail tank cars with this material. Your heart beating fast, you respond. " A: Use HYPERFILL®. The cooling rate is acceptable for this material and productivity gains are important given the large size of the product. B: "Use HYPERFILL®, for the same reasons as (A), BUT we need to change materials to a low carbon stainless steel (e.g. 304L) or we will get corrosion failure in the HAZ." C: "Use GMAW-P. For this material, this heat input is best. " D: "Use GMAW-P, for the same reasons as (C), but we need to change materials to a low carbon stainless steel (e.g. 304L) or we will get corrosion failure in the FZ."
Coupling will be used in the drive mechanism of the roles used in the Continuous Casting plant. The moment to be transmitted is high, the transmission distance is about 1500 mm, and there are fluctuations in the bending direction. Which type of coupling is best suited to absorb these fluctuations? Explain broadly the features of this coupling. Draw it schematically and explain the working principle.

Which of these factors causes more porosity to form toward the interior of a casting rather than toward the outside? (a) Gasses are less soluble in the solid metal than the liquid, so solidified areas push dissolved gasses toward the interior. (b) Casting under a vacuum causes gasses near the liquid metal surface to be drawn out of the liquid during solidification. (c) The feeding structures of the mold are designed to force entrapped air into the center of the casting. (d) Draft on the mold wall forces air bubbles toward the interior of the solidifying metal. (e) None of the above Non-eutectic alloys (most commercial alloys) solidify over a temperature range. Which of the following statements explains how this affects the casting process. (a) Solidified non-eutectic alloys are especially difficult to remove from metal dies (b) Non-eutectic alloys have significantly less fluidity than pure metals or eutectic alloys. (c) Non-eutectic alloys solidify starting from the outside of the…
