6G-lasser to specjalista, który potrafi wykonać złącze rurowe w jednej z najtrudniejszych pozycji: rura jest zamocowana pod kątem, a spawacz musi kontrolować jeziorko spawalnicze w wielu położeniach bez obracania elementu.
Wat betekent de 6G-positie?
The 6G position covers welding a pipe set at an angle and fixed in place. In practice it requires uphill, overhead, side and intermediate-position werk. That is why a 6G certificate is treated as proof of very high skill.
Verschil tussen 1G, 2G, 5G en 6G
In 1G the element can be rotated, in 2G the pipe is vertical, in 5G it remains fixed on the horizontal axis, and 6G combines several difficulties at once. A good 6G welder can usually handle most positions found on process installations.
Waar is het nodig?
Most often on process piping in refineries, petrochemicals, LNG terminals, energy and gas installations. There, weld quality directly affects safety, tightness and technical acceptance of the installation.
Materialen en normen
6G-lassers pracują na stali węglowej, nierdzewnej, duplex, P91/P92, P460, a czasem również na stopach niklu, takich jak Inconel. Certyfikacja opiera się najczęściej na EN ISO 9606-1 albo ASME IX, w zależności od projektu.
Kwaliteitscontrole
Welds on industrial sites undergo RT, UT, PT or VT testing. A high NDT level means the welder must know the WPS, control parameters and understand how joint preparation affects the final result.
Waarom zijn de tarieven hoger?
There are fewer 6G lassers than werkers with basic qualifications, and refinery and gas projects cannot afford random quality. That is why specialists with current certificaten, weld history and shutdown experience are constantly in demand.
Rol van Staffeo
Staffeo maintains a database of 6G lassers with current certificaten, checks qualification scope and matches candidates to the material, method, position and NDT requirements of the specific project.
FAQ
Vervangt 6G alle andere posities? It often covers a broad range, but the certificate, method, material and thickness always decide.
Hoe lang is het certificaat geldig? Continuity is usually confirmed every 6 months by the employer or an authorized person.
