    Evaluation of welding and welding process of the use of materials 1, evaluation of welding materials used According to the requirements of the actual working condition and the structure of the corresponding technology, put forward the test items necessary. All welded joints will withstand a certain load (dynamic or static load is less, so any requirements of welding structure, almost all the tests of mechanical properties at room temperature and most of them are for the welded joint, and others in the weld metal. Joint work in high or low temperature conditions, it is necessary to test the corresponding temperature: such as creep rupture strength test, the material to determine the high temperature properties (creep limit and the pupa becomes elongation and creep rate, rupture strength and endurance limit elongation and section shrinkage rate of the corresponding temperature); Charpy V notch impact test to determine the impact of joint under low temperature toughness and impact toughness of the material was measured by the drop weight test; the nil ductility transition temperature. Corrosive conditions in the medium, the corrosion resistance test should be carried out in different (such as resistance to general corrosion, intergranular corrosion, pitting corrosion, crevice corrosion test). In the wear condition wear test shall be conducted accordingly (such as abrasive wear test, wear test, impact resistance and wear test). Aging embrittlement of materials, joint should be thermal strain aging embrittlement sensitivity test. 2, evaluation of welding materials Refers to the evaluation of the welded joints have the tendency of welding defects, to make reasonable welding procedure specification (WPS) support. With steel, for example, is the main chemical composition of materials as the basis for indirect assessment of "carbon equivalent" to the joint and crack resistance test of direct test method.
