This article describes the main clauses of T/CWAN 0013-2019 "Specification for quality of aluminum and aluminum alloy wires and rods" and the differences between it and GB/T 10858-2008 "aluminum and aluminum alloy welding wire". The reasons for adding and changing these clauses are analyzed. The analysis shows that the formulation of this group standard can greatly promote the development of domestic aluminum and aluminum alloy welding wire

and provide a basis for the construction of the domestic welding material evaluation standard system. However

some clauses and cited documents of the standard are improper

and the relevant departments should make corrections as soon as possible or issue corresponding amendments.
