Destructive testing of Weldments Welding Technology/5.6 Destructive testing of Weldments

Destructive Testing of Weldments Destructive weld testing, as the name suggests, involves the physical destruction of a completed weld to evaluate its strength and characteristics. Welding Technology/5.6 Destructive testing of Weldments

Toughness testing In actual practice, engineering components during service are invariably subjected to various kinds of loads namely static and dynamic loads which are classified on the basis of the rate of change in magnitude of load and direction. Dynamic loads are characterized by high rate of change in load magnitude and direction. Reverse happens in case of static loads. In the hardness test and tensile tests, load is increased very slowly that corresponds to the behaviour of material under more or less static loading condition. Moreover, very wide range rate of loading (0.0001 to 1000mm/min) can be used in tensile test. Welding Technology/5.6 Destructive testing of Weldments

Toughness testing The toughness test simulates service conditions often encountered by components of the system used in transportation, agricultural, and construction equipment. A material high impact resistance is said to be a tough material. Toughness is the ability of a material to resist both fracture and deformation.
