Laser welding of zinc-coated steel with tandem beams: Analysis and comparison

Lazer Kaynağı ve Lazer Kaynağının Başlıca Uygulamaları

“…Galvanizli çeliklerin lazer kaynağında çinko elementi istenmeyen buharlaşma meydana getirdiğinden bu malzemelere çiftli lazer kaynak yöntemi uygulanır. Bu yöntemde, parça yüzeyine ilk olarak kesme ışını ve akabinde de kaynak ışını gönderilerek kaynak işlemi yapılmaktadır [11]. Lazer kaynak teknolojisinin kullanılmasıyla birlikte kaynak parametreleri ve kaynak kalitesinin ölçümü de yapılabilmektedir.…”

Laser dimpling process parameters selection and optimization using surrogate-driven process capability space

“…Al & Cu) into the faying surface which absorbs zinc vapour or reacts with zinc vapour in such a way that a liquid alloy with a high boiling point is formed [17,18];  Tandem beams -This approach employs a dual laser beam or a secondary heat source. The first beam applies pre-heating which vaporizes zinc coating and second beam performs actual welding [19][20][21];…”

Modified Twin-Spot Laser Welding of Complex Phase Steel

“…the use of two lasers or the use of a special optical element making it possible to split a laser beam [15]. Twin-spot laser beam welding is also used for welding galvanised steels, where the first beam is used for creating a duct enabling the discharge of zinc vapours, whereas the second beam is used for making a welded joint as such [16]. Milberg et al [17] stated that, when welding galvanised steels, the use of the twin-spot beam significantly improves the quality of welded joints (decreases the number of imperfections), in comparison with conventional methods.…”
