“…The large sizes of the prior β have been reported to reduce the mechanical strength of Ti6al4V. Generally, when the microstructure of the samples was compared with that of Omoniyi et al, [12], which were welded autogenously, the material exhibited the same microstructural transformation, which could be due to the huge similarities between the Ti6al4V eli and Ti6al4V.…”

“…however, tungsten inert gas (TiG) provides a good joining strength and is relatively economical compared to other techniques [11]. despite the excellent joining techniques, one of the limitations of Ti6al4V is the oxidation of the material at a temperature of 350°C and above [12,13]. The oxidation results in contamination of the weld, resulting in reduced material mechanical strength [14].…”

Titanium and its alloys have significant uses in the biomedical, chemical, and aerospace industries. in this article, the current and gas flow rates were varied using Taguchi's experiment design. The mechanical properties of the welded joint made using tungsten inert gas (TiG) welding and Ti6al4V eli as filler metal was characterized using the microstructure, microhardness, and tensile strength. The joint was classified into three regions, namely, fusion zone (FZ), heat affected zone (haZ), and base metal (bm). Results show martensitic microstructure within the fusion zone (FZ) and the heat affected zone (haZ), which resulted in an increased hardness within the fusion and heat affected zone.

“…Lazer ışını malzemeyi ısıtıp eşik sıcaklığa ulaşıldığında malzemedeki atomlar arasındaki bağlar kopar ve malzeme buharlaşır. Buhar sıcaklığı daha da artırılırsa, buharlaşmış metal atomlarının elektronları ve etkileşim bölgesindeki gazlar atomlardan uzaklaştırılabilir, bu da iyonize gaz, yani plazma ile sonuçlanır [14].…”

Lazer kaynağı endüstriyel uygulama alanlarında kullanılmaktadır. Modern birleştirme yöntemlerinden biri olan lazer kaynağı geliştirilmeye devam etmektedir ve mevcut kaynak yöntemlerine karşı hassasiyet, hız ve esneklik gibi önemli avantajlar sunmaktadır. Bu çalışmada; lazer kaynağı yöntemiyle paslanmaz çeliklerin birleştirilmesi hakkında literatürde mevcut çalışmalar detaylı şekilde araştırılmıştır. Değerlendirilen çalışmalar sistematik şekilde analiz edilmiş ve gruplandırılarak araştırmacıların dikkatine sunulmuştur. Araştırmalar özellikle lazer kaynakta derinlemesine nüfuziyet yöntemiyle elde edilen anahtar deliğinin incelenmesi, lazer kaynak parametrelerinin kaynakların mekanik özellikleri üzerindeki etkisinin incelenmesi, lazer kaynak parametrelerinin kaynaklı bağlantının mikroyapısal özellikleri üzerindeki etkisinin incelenmesi ve lazer kaynak proses parametrelerinin malzemenin çekme dayanımı, yorulma dayanımı ve sıcaklık dağılımına etkilerinin incelendiği konulara yoğunlaşmıştır.

“…These contaminations caused by atmospheric gases have been reported to affect the microstructure of welds. Coarse columnar grains and α’ martensitic microstructure have been reported to be responsible for brittleness, high microhardness, and reduced ductility 15 . Therefore, the ductility and toughness of welds and additive manufactured products can be improved through heat treatment 11 , 16 .…”

“…Laser welding (LW) is preferred in areas where high strength is required, such as the marine and aerospace industries. The smaller area of the weld zone (WZ) as a result of low heat input and high welding speed, compared to other fusion welding techniques such as metal inert gas (MIG) welding and tungsten inert gas (TIG) welding has made it advantageous 15 , 17 . Even though Ti6Al4V additive manufactured parts have been welded using different fusion processes as reviewed, the parameter selection has not achieved full penetration in some cases.…”

The feasibility of joining laser metal deposited Ti6Al4V sheets using laser beam welding was investigated in this article. The additive manufactured sheets were joined using a 3 kW CW YLS-2000-TR ytterbium laser system. The mechanical properties and microstructure of the welded additive manufactured parts (AM welds) were compared with those of the wrought sheets welded using the same laser process. The welds were characterized and compared in terms of bead geometry, microhardness, tensile strength, fractography, and microstructure. The differences in characteristics are majorly found in the width of the bead and tensile strength. The bead width of AM welds appear wider than the wrought welds, and the wrought welds exhibited higher tensile strength and ductility than the AM welds.
