BS EN ISO 636:2015 pdf download – Welding consumables — Rods, wires and deposits for tungsten inert gas welding of non-alloy and fine-grain steels — Classification 1 Scope 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 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 ] of all-weld metal or utilizing asystem based upon the tensile strength and the average impact energy of 27 ] of all-weld metal. a) 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 ] of all-weld metal in accordance with this International Standard. b) 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 ofall-weld metal in accordance with this International Standard. Paragraphs and tables which have neither the suffix letter “A” nor the suffixletter”B” are applicableto all rods and wires classified in accordance with this International Standard. 2Normative references The following documents, in whole or in part, are normatively referenced in this document and areindispensable for its application.For dated references,only the edition cited applies.

The two designation approachesinclude additional designators for some other classification requirements,but not...
