ISO 17634:2015 pdf free.Welding consumables一Tubular cored electrodes for gas shielded metal arc welding of creep-resisting steels
ISO 17634 specifies requirements for classification of tubular cored electrodes used in the post-weld heat-treated condition for gas shielded metal arc welding of creep-resisting and low alloy elevated temperature steels. One tubular cored electrode can be tested and classified with different shielding gases.
ISO 17634 is a combined specification providing for classification utilizing a system based upon the chemical composition of all-weld metal or utilizing a system based upon the tensile strength and the chemical composition of all-weld metal.
1) Paragraphs and tables which carry the suffix letter “A” are applicable only to tubular cored electrodes classified to the system based upon chemical composition with requirements for the yield strength and the average impact energy of 47J of all-weld metal in accordance with this International Standard.
2) Paragraphs and tables which carry the suffix letter “B”are applicable only to tubular cored electrodes classified to the system based upon the tensile strength and chemical composition 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 tubular cored electrodes classified in accordance with this International Standard.
It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed current, but for the purposes of this International Standard, pulsed current is not used for determining the electrode classification.
