Yes Yes Yes QW Arc-welded joints in aluminium and its weldable alloys. Fusion-welded joints in steel, nickel, titanium and their alloys beam welding excluded. Guidance on quality levels for imperfections Status: Assemblages en aluminium et alliages d’aluminium soudes a l’arc.
The quality levels given in this International Standard provide basic reference data and are not specifically related to any particular application. vs
The faster, easier way to work with standards. Many eb 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.
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.

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 This is provided that they continue to work with the same type of welding unit, the welding process is not changed and they work in accordance with an approved procedure.
It contains a simplified selection of arc welding imperfections based on the designations given in ISO Arc-welded joints in aluminium and its alloys. The faster, easier way to work with standards.
It applies to material thicknesses above 0,5 mm. Guidance on quality dn for imperfections. Quality levels for imperfections Status: Definitions are given in clause 3 where: The employer must endorse on the approval certificate at six monthly intervals that this is so.
BS ISO 30042:2008
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 b 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.
July Replaced By: A simple and inexpensive non-destructive examination technique that is sometimes overlooked is that of a thorough visual examination by a suitably trained and experienced welding inspector. It provides three sets of dimensional values from which a selection can be made for a particular application.

It covers full-penetration butt welds and all fillet welds. It is possible, therefore, that different quality levels are applied to individual welded joints in the same product or component.
Niveaux de qualite par rapport aux defauts. 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.
