45、lications The most usual alloy types are listed in Table 2. Typical application is given in Table A.1. The forms of supply listed in Tables A.2 and A.3 may support the decision making as regards applicable welding processes. The applications shown in Table A.4 give reference to the suitability of in

46、dividual alloy types for different kind of requirements and system structures. It may be concluded that other alloy types may also be considered with regard to complex kind of requirements. 6 Chemical composition The chemical analysis shall be performed on specimens of solid wires, solid rods and solid strips according to EN ISO 6847 respectively or on any suitable all-weld metal specimen and cast rods (covered electrodes, cored wires, cored strips, sintered rods, sintered strips and metal powder).
