This document contains three quality levels, B stringent, C intermediate and D moderate, the choice of which depends upon design considerations, subsequent fabrication activities such as rolling or pressing, 11 Weld defects and quality control Table Recommendations for welding of metallic materials Arc welding of ferritic steels. Yes Yes Yes QW If the required acceptance level for the defects listed above is not con- tained within a relevant application standard then it is the responsibility of the designer to select the appropriate quality level.

Guidance on quality levels for imperfections Status: Worldwide Standards We can source any standard from anywhere in the world. The principles may also be applied to partial-penetration butt welds. Search all products by.

Arc-welded joints in aluminium and its weldable alloys. Other defects not listed are mainly those of geometry and include misshapen and incor- rectly sized welds,variable cap width and height,weld face roughness, incom- plete weld fill and asymmetry of fillet welds.

The quality levels given in this International Standard provide basic reference data and are not specifically related to any particular application. Click to learn more. Similarly, if non-destructive testing is to be correctly performed and defects accurately identified and sized, well-trained and experienced non- destructive evaluation NDE operatives are needed.

The quality level will have to be prescribed before the start of production, preferably at the enquiry or order stage.

It is possible, therefore, that different quality levels are applied to individual welded joints in b same product bbs component. The faster, easier way to work with standards. Guidance on quality levels for imperfections.

Many of these defects are caused by the welder, because of either a lack of care or a lack of skill, and emphasise the need for adequate training. If the employer keeps records of non-destructive or mechanical tests carried out at a maximum of six month periods and these confirm that the required quality is being maintained then the examining body can endorse the approval certificate at the end of the two year valid- ity period for further periods of two years.
