The purpose ej this International Standard is to define the dimensions of typical imperfections which might be expected in normal fabrication.
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 enn welding.

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.

Arc-welded joints in aluminium and its weldable alloys. Qualification for a fillet weld is by macro-examination and fracture testing. A bend or tensile test must be carried out if the MIG welding process is used. Learn more about the cookies we use and how to change your settings. Testing is to the requirements of EN Part 8.

The employer must endorse on the approval certificate at six monthly intervals that this is so. Accept and continue Learn more about the cookies we use and how to change your settings. 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.

It is possible, therefore, that different quality levels are applied to individual welded joints in the same product or component. Take the smart route to manage medical device compliance. Lichtbogenschweissverbindungen an Aluminium und seinen Legierungen. Definitions are given in clause 3 where: 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.

Such an examination will identify many defects, particularly those of shape as listed in Section 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 faster, easier way to work with standards. Worldwide Standards We can source any standard from anywhere in the world. 300442, 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.
Fusion-welded joints in steel, nickel, titanium and their alloys beam welding excluded. 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. 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 bss rolling or pressing, 11 Weld defects and quality control Table Niveaux de qualite par rapport aux defauts.
