英文名称：Welding consumables — Rods, wires and deposits for tungsten inert gas welding of non-alloy and fine-grain steels — Classification
发布日期：2015-11
标准范围
This International Standard specifies requirements for classification of rods and wires in the asweldedcondition and in the post-weld heat-treated condition for tungsten inert gas welding of nonalloyand fine-grain steels with a minimum yield strength of up to 500 MPa or a minimum tensilestrength of up to 570 MPa.This International Standard is a combined specification providing classification utilizing a systembased upon the yield strength and the average impact energy of 47 J of all-weld metal or utilizing asystem based upon the tensile strength and the average impact energy of 27 J of all-weld metal.a) Paragraphs and tables which carry the suffix letter “A” are applicable only to rods and wiresclassified to the system based upon the yield strength and the average impact energy of 47 J of allweldmetal in accordance with this International Standard.b) Paragraphs and tables which carry the suffix letter “B” are applicable only to rods and wiresclassified to the system based upon the tensile strength and the average impact energy of 27 J ofall-weld metal in accordance with this International Standard.c) Paragraphs and tables which have neither the suffix letter “A” nor the suffix letter “B” are applicableto all rods and wires classified in accordance with this International Standard.
