Welding consumables. Tubular cored electrodes for metal arc welding with and without a gas shield of non aloy and fine grain steels. Classification.
Le présent document spécifie les prescriptions de classification des fils fourrés à l'état brut de soudage pour le soudage à l'arc avec ou sans protection gazeuse des aciers non alliés et à grains fins ayant une limite d'élasticité minimale pouvant atteindre 500 N/mm carré.

ISO 17632:2004 specifies requirements for classification of tubular cored electrodes with or without a gas shield for metal arc welding of non-alloy and fine grain steels in the as-welded condition or in the post weld heat treated condition with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa. One tubular cored electrode can be tested and classified with different shielding gases, if any. ISO 17632:2004 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.
