AWS APG-DISC- POCKET GUIDE FOR VISUAL EXAMINATION OF WELDS – DISCONTINUITY CAUSES AND REMEDIES
| Size: 4.3 MB| Format:PDF| Quality:Scanner| Publisher: American Welding Society, Inc. (AWS) | Year: 2018| pages: 45
Visual examination (abbreviation: VT) is the primary method for identifying welding discontinuities. It is fundamental to any effective quality control program. It is also fundamental to assuring weld repair operations are effective and comply with the approved contract documents. For convenience and brevity, all rework and repair activities in this pocket guide are called repairs. As a minimum, various steps in any repair are always examined and evaluated. Welders and inspectors, alike, will examine the repair efforts and compare them with project requirements. Even "close enough" is an evaluation. It has been proven time and time again that integrating quality control actions into fabrication and installation operations reduces labor efforts and repair costs. Early detection of welding discontinuities and other quality failures saves money and time.

AWS A5.36/A5.36M-2012 (NOT ACTIVE STANDARD): Specification for Carbon and Low-Alloy Steel Flux Cored Electrodes for Flux Cored Arc Welding and Metal Cored Electrodes for Gas Metal Arc Welding
AWS A5.36/A5.36M, 1st Edition, 2012 - Specification for Carbon and Low-Alloy Steel Flux Cored Electrodes for Flux Cored Arc Welding and Metal Cored Electrodes for Gas Metal Arc Welding
This specification prescribes requirements for the classification of carbon and low-alloy steel flux cored electrodes for flux cored arc welding (FCAW), either with or without shielding gas, and carbon and low-alloy steel metal cored electrodes for gas metal arc welding (GMAW). This new specification replaces both AWS A5.20/A5.20M, Specification for Carbon Steel Electrodes for Flux Cored Arc Welding, and AWS A5.29/A5.29M, Specification for Low-Alloy Steel Electrodes for Flux Cored Arc Welding. It also includes provisions for the classification of carbon and low-alloy steel metal cored electrodes which previously had been classified according to AWS A5.18/A5.18M, Specification for Carbon Steel Electrodes and Rods for Gas Shielded Arc Welding, or AWS A5.28/A5.28M, Specification for Low-Alloy Steel Electrodes and Rods for Gas Shielded Arc Welding, as applicable. Iron is the only element of the undiluted weld metal deposited by the electrodes classified under this specification whose content exceeds 10.5%.
Safety issues and concerns are addressed in this standard, although health issues and concerns are beyond the scope of this standard. Some safety and health information can be found in nonmandatory Annex A, Clauses A5 and A10. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.11 and applicable federal and state regulations.
This specification makes use of both U.S. Customary Units and the International System of Units (SI). The measurements are not exact equivalents; therefore, each system must be used independently of the other without combining in any way when referring to weld metal properties. The specification with the designation A5.36 uses U.S. Customary Units. The specification A5.36M uses the International System of Units (SI). The latter are shown within brackets ([ ]) or in appropriate columns in tables and figures. Standard dimensions based on either system may be used for the sizing of electrodes or packaging or both under the A5.36 and A5.36M specifications.
