EN ISO 636:2008 Welding consumables - Rods, wires and deposits for tungsten inert gas welding of non-alloy and fine-grain steels - Classification [Superseded: CEN EN 1668, CEN EN 1668]
This International Standard specifies requirements for classification of rods and wires in the as-welded
condition and in the post-weld heat-treated condition for tungsten inert gas welding of non-alloy and fine grain
steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.
This International Standard is a combined specification providing classification utilizing a system based upon
the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon
the tensile strength and the average impact energy of 27 J of all-weld metal.
1) Paragraphs and tables which carry the suffix letter “A” are applicable only to rods and wires classified
to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal
in accordance with this International Standard.
2) Paragraphs and tables which carry the suffix letter “B” are applicable only to rods and wires classified
to the system based upon the tensile strength and the average impact energy of 27 J of all-weld
metal in accordance with this International Standard.
3) Paragraphs and tables which have neither the suffix letter “A” nor the suffix letter “B” are applicable
to all rods and wires classified in accordance with this International Standard.
