An arc cutting process in which metals to be cut are melted by the heat of carbon arc and the molten metal is removed by a blast of air.
Process of holding metals or alloys at room temperature after subjecting them to shaping or heat treatment, for the purpose of increasing dimensional stability or to improve their hardness and strength through structural changes, as by precipitation.
Surfaces, solidifies to produce an adhesive bond.
