GB/T 39280-2020 Rods, wires and deposits for tungsten inert gas welding of non alloy and fine grain steels

Scope: This standard specifies the types, technical requirements, test methods, re-inspection and supply technical conditions of non-alloy steel and fine-grain steel solid filler wire for tungsten inert gas shielded arc welding. This standard is applicable to non-alloy steel and fine-grain steel solid filler wire (hereinafter referred to as "welding wire") for tungsten inert gas arc welding whose minimum tensile strength requirement value of the deposited metal is not greater than 570 MPa.
