Q. Explain Moulding Sand for Non-ferrous Casting?
The melting point of non- ferrous metal is much lower than that of ferrous metals. Therefore, the moulding sands for non-ferrous casting may be less refractory and permeable. Also, a smooth surface is desirable on non-ferrous casting. Due to all this, the moulding sands for non-ferrous casting contain a considerable amount of clay and fine grained.
Q. Use of Stainless Steels in welding? Considerable care must be exercised to obtain sound, crack-free welds. These difficulties are pronounced when welding very high-chromium
Determine the shear stress in each section - cells: In Figure, the mean dimensions of the two cells are 100 mm × 50 mm and 50 mm square. t 1 = 3 mm, t 2 = 6 mm,
A pressure vessel is to be treated to generate compressive residual stresses on it inner surface. This involves increasing the pressure until taking 75% of the wall thickness goe
