Workshop Technology
In a gas welding of mild steel using an oxyacetylene flame, the total amount of acetylene consumed is 10 litres. The oxygen consumption from the cylinder is
Is used for reducing the diameter of round bars and tubes by rotating dies which open and close rapidly on the work
Is used to improve fatigue resistance of the metal by setting up compressive stresses in its surface
Consists of pressing the metal inside a chamber to force it out by high pressure through an orifice which is shaped to provide the desired form of the finished part
