It is possible, therefore, that different quality levels are applied to individual welded joints in the same product or component.
Welding Aluminum & It’s Alloys
Yes Yes Yes QW As in the point above testing is to the requirements of EN Part 8. It applies to material thicknesses above 0,5 mm. Click to learn more.
The employer must endorse fn the approval certificate at six monthly intervals that this is so. Guidance on quality levels for imperfections Status: It provides three sets of dimensional values from which a selection can be made for a particular application. For special purposes, additional details may to be prescribed. Quality levels for imperfections Status: Arc-welded joints in aluminium and its alloys. You may find similar items within these categories by selecting from the choices below:.
Definitions are given in clause 3 where: 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.
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.
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. Testing is to the requirements of EN Part 8. Such an examination will identify many defects, particularly those of shape as listed in Section Search all products by. Click to learn more. 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 The specification makes it clear that only those opera- tors responsible for setting up and adjusting operating parameters during welding need to be approved.
It contains a simplified selection of arc welding imperfections based on the designations given in ISO The approval is valid for a period of six months. The principles may also be applied to partial-penetration butt welds. The faster, easier way to work eh standards. Assemblages en aluminium et alliages d’aluminium soudes a l’arc. A bend or tensile test must be carried out if een MIG welding process is used. Automatic and robotic welding approval using a multi- run technique gives approval for welding with a single run but not vice versa; approval to weld without a sensor gives approval for welding with a sensor but not vice versa; changing the robot type, system or control unit requires re-approval as does any change to the other essential variables.
This test may be carried out on non-standard test pieces, on test pieces simulat- ing production or on actual production items that have been identified as test pieces prior to welding.

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.
