Quality based on structural welding codes Following structural welding codes such as AWS D1.1, D1.2, D1.6 and others, provides a cost effective method of producing quality welds. The premise here is that you will qualify a welding procedure by testing to prove that it is capable of producing sound welds. ASME and AWS welding codesSimilarities and differencesThe most commonly used codes for qualifying welders are the American Society of Mechanical Engineers (ASME) Section IX and American Welding Society (AWS) D1.1. Committees and subcommittees comprising volunteer workers interested in furthering the quality and efficiency of the welding industry work together to develop these codes.
Code Requirements All NDT Requirements Any verification inspection required (other than fabricators inspection) Weld acceptance criteria (if different from clause 6 of the code) CVN toughness criteria for weld metal, base metal, and/or HAZ when required.

Figure 5C. Lap joint with a double fillet weld should have a 1 in. (25 mm) minimum overlap. A single fillet and shorter overlap may suffice when less strength is required. Figure 5D. Compared to a single fillet, a T-joint with a double-fillet weld produces maximum joint strength. Shortest side of the fillet should be equal to the material Codes & Standards - ASMEASME publishes cases and interpretations that supplement our standards and codes. Becoming an ASME Member.

Grounding of electrical circuits is a safety practice that is documented in various codes and standards. A typical arc welding setup may consist of several electrical circuits. Applying and maintaining proper grounding methods within the welding area is important to promote electrical safety in the workplace. How To Qualify Welders WELDING ANSWERSThese documents should specify which code or standard you must follow for the qualification of your welding procedures and welders. Codes such as AWS D1.1, D1.2, D1.6, API 1104 or ASME Section IX may be called. If there is no specified code or standard you have two good choices:

This standard supercedes these standards: CAN/CSA Z183 Oil Pipeline Systems CAN/CSA Z184 Gas Pipeline Systems CAN/CSA Z187 Offshore Pipelines . Other CSA Piping and Component Codes:B 51 Boilers and Pressure Vessels . B 53 Identification of Piping Systems . B 52 Mechanical Refrigeration Code . B 63 Welded and Seamless Steel Pipe SPOT WELDING TECHNICAL INFORMATION - Tite-Spot The depth of depression on the sheet surfaces caused by welding electrodes should never exceed 25 percent of the sheet metal thickness. Typically a body shop welds steel between 16 gauge and 24 gauge. If a spot welder has adjustable length tongs, a pressure gauge
I think the ASME Codes and Standards committees' most important work is to be able to provide consistency throughout the nation and through North AmericaAn elevator is an elevator and if you build an elevator in California, you should be able to sell it in Ohio, and if you build it in Ohio, you should be able to sell it in Ontario. Standard Welding Procedure Specifications (SWPS To be referenced as a supporting document for an SWPS, a PQR received from an industry or government agency must be qualified and documented in accordance with one of the nationally recognized codes or specifications such as AWS D1.1 through AWS D1.6, AWS D15.1, AWS D14.1 through AWS D14.6, ASME Boiler and Pressure Vessel Code, Section IX, NAVSEA Technical

Before you invest in the testing required to qualify and certify processes and welders under a code, you must first obtain a copy of the code you are planning to use. True Every product welded should be manufactured to the same level, and codes and standards ensure this. Welding - Personal Protective Equipment and Clothing :The CSA Standard W117.2 states that contact lenses should not be worn by welders and welding personnel because foreign bodies (objects) in the eye can cause excessive irritation. Contact lenses do not provide protection from ultraviolet radiation and flying objects.
When NFPA 13 requires qualification to one of these standards, it means that the WPS has to address certain elements of how to do welding that the codes call variables; among these are: Welding process or processes (i.e., stick, MIG, flux core, etc.) Base metal (i.e., A-53, A-139, etc.) Welding, Cutting, and Brazing - Overview Occupational Standards.
