TAPER TURNING - Practice Mode
2) How is the filler material distributed in the joint in braze welding?
Correct Answer: By capillary action
Explanation:
Cast iron in which carbon is present in combined form or in carbide form known as white cast iron. White colour is due to carbide formation. It contain up to 2.3 percent carbon. It is hard and not suitable for machining. This iron has high tensile strength and a low compressive strength.
4) Which material is used for making the head of soldering iron?
Correct Answer: Forged copper
Explanation:
Cast iron which contain carbon in free form, known as Gray cast iron. It is also known as commercial cast iron due to mostly used in commercial purpose. It contains 3 to 3.5 percentile carbon and rest iron. This cast iron has low tensile strength, high compressive strength and no ductility. It has excellence machining property. This metal is designate by FG followed by the digit show maximum tensile stress.
5) Which one is the disadvantage of using tail stock offset method?
