AWS- A5.22/A5.22M:2012 Stainless Steel Flux Cored and Metal Cored Welding Electrodes and Rods


Classification and other requirements are specified for numerous grades of flux cored and metal cored stainless steel electrodes and rods. New classifications include a duplex alloy and three high carbon classifications not previously classified. New classifications also include all of the metal cored electrodes that are currently in A5.9/A5.9M. In the next revision of A5.9/A5.9M these metal cored electrodes will be deleted from that specification. 

Designations for the flux cored electrodes and rods indicate the chemical composition of the weld metal, the position of welding, and the external shielding gas required (for those classifications for which one is required). Designations for the metal cored electrodes indicate the chemical composition of the weld metal only. 

The requirements include general requirements, testing, and packaging. Annex A provides general application guidelines for individual alloys and other useful information about welding electrodes. ANSI Approved. approx.

A5.10/A5.10M:2012 (ISO 18273) Welding Consumables – Wire Electrodes, Wires and Rods for Welding of Aluminum and Aluminum-Alloys – Classification, prescribes requirements for the classification of bare, wrought and cast aluminum-alloy electrodes and rods for use with the gas metal arc, gas tungsten arc, oxyfuel gas, and plasma arc welding processes. This specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other. Approx 45 pages. ISBN 0871715503

This standard contains the essential welding variables for chromium-molybdenum steel in the thickness range of 1/8 through 1/2 in. in the as-welded condition, or 1/8 in. through 1-1/2 in. in the postweld heat treated (PWHT) condition, using manual shielded metal arc welding. It cites the base metals and operating conditions necessary to make the weldment, the filler metal specifications, and the allowable joint designs for groove welds. This welding procedure specification (WPS) was developed primarily for pipe applications. ISBN 087171-593-7
