“…Dari hasil penelitian tersebut didapatkan bahwa dalam sudut kritis sinar laser akan mengalami beberapa perbedaan yang ditemukan dalam kekerasan antara zona lasan dan zona yang terkena dampak panas dari spesimen. Selain itu, variasi sudut juga memiliki sedikit efek pada ukuran butir dan struktur mikro dari lasan dan zona yang terkena panas [9]. Tiago Vieira da Cunha melakukan sebuah penelitian tentang Analisis pengaruh kuat arus terhadap hasil pengelasan dalam pengelasan TIG.…”

This study aims to determine the various effect of heat input due to varied electric current on microstructure of the weld joints and the bending strength of 2 dissimilar metals (aluminum alloy 5052 and galvanized steel) with Al-Si 4043 as filler. This experimental research was worked out by varying the strength of the current which can then be calculated into a heat input. The current inputs applied were 30.8 J / mm (70A), 35.2 J / mm (80A) and 39.6 J / mm (90A) while the protective gas flow rate used is 14 liters / minute. This study showed that the increase in heat input greatly affects the shape of the weld area microstructure, i.e. the microstructure and bending strength. Greater heat input due to higher current can melt larger area, so that the join process occured better. The highest bending strength at 9.05 Mpa was achieved for heat input at 39.6 J / mm or strong current of 90 A. The weakest bending strength at 8.88 Mpa was achieved for heat input at 35.2 J / mm or a strong current of 70 A.

“…In contrast, laser-cleaning technology offers substantial benefits over traditional processes in terms of flexibility, consumable costs, and environmental impact. It has gained widespread application in diverse fields, including pre-soldering cleaning, metal decontamination, and the restoration of cultural artefacts [9][10][11]. Zhang et al [12] identified that at low energy densities, the primary mechanism of laser cleaning of metal oxides is ablation, where high-energy pulsed lasers not only cause phase explosion but also facilitate oxide layer removal through pressure-induced shock effects.…”

The rusting of metals brings huge losses to the industry every year, and post-treatment of rusted metals to restore their properties to the initial state is a hot topic of current research. In particular, 20 steel, which is widely used in various structural components such as ships, is prone to oxidation in atmospheric environment. Therefore, in this study, a nanosecond pulsed laser was used to remove the rust layer on the surface of 20 steel. The effects of different energy densities and spot overlap rates on the roughness, surface morphology, chemical composition, microhardness and corrosion resistance of the rust layer were analyzed. The results showed that the best cleaning effect was achieved at an energy density of 4.26 J/cm2 and a spot overlap rate of 75%. Under these conditions, the rust layer was completely removed without damage to the substrate, and it even improved the corrosion resistance of 20 steel. At energy densities of 1.42 J/cm2 and 2.84 J/cm2, the rust layer was not completely removed, while at 5.68 J/cm2, the rust layer was removed but the substrate was damaged. In addition, the mechanism of rust removal and substrate damage is discussed.
