Microstructure and Tensile Behaviors of Laser-Arc Hybrid Welds Comparing to Submerged Arc Welds of High-Manganese Steel for Cryogenic Applications
Myeonghwan Choi, Kwang-Hyeon Lee, Dae-Won Cho, Namhyun Kang
Korean J. Met. Mater.
2025;63(1):33-42. Published online 2025 Jan 5
DOI:
https://doi.org/10.3365/KJMM.2025.63.1.33
Abstract
The weldability and the relationship between microstructure and tensile properties at 298 and 110 K produced by laser-arc hybrid welding (LAHW) in high-Mn steel welds were thoroughly investigated. In the laser zone of LAHWs using filler wire, more Mn vaporization in the laser zone was observed than at the arc.....

Laser Cladding of Alloy 82 Powder for Corrosion Protection in Small Modular Reactors
소형원자로 내식성 향상을 위한 Alloy 82 분말의 레이저 클래딩 연구
Insung Choi, Won-Chan Jeong, Dan-Bi Song, Jeong Suh, Kwang-Hyeon Lee, Yongjai Kim, In-Chul Jung최인성, 정원찬, 송단비, 서정, 이광현, 김용재, 정인철
Korean J. Met. Mater.
2023;61(8):561-572. Published online 2023 Jul 24
DOI:
https://doi.org/10.3365/KJMM.2023.61.8.561
Abstract
There has been an increased demand for surface modification technologies to enhance corrosionresistance and wear-resistance. Among the representative surface coating technologies, laser cladding has attracted great attention because of its multiple advantages including low heat input, low dilution ratio, controllable clad height, etc. Recently, laser cladding has been considered as.....

Effect of Interfacial Intermetallic Compounds Morphology on Mechanical Properties of Laser Brazing of Aluminum to Steel
Kwang-Hyeon Lee, Su-Jin Lee, In-Duck Park, Kwang-Deok Choi, Chung-Yun Kang, Jeong Suh, Tae-Jin Yoon
Korean J. Met. Mater.
2021;59(9):640-651. Published online 2021 Aug 4
DOI:
https://doi.org/10.3365/KJMM.2021.59.9.640
Abstract
The paper provides experimental details of the welding and specific examples of welding aluminum welding battery cans and conductive tabs for battery pack manufacture. In this study, we provide experimental details of a process for joining dissimilar materials used in sealing battery parts. A laser brazing technique was used for.....
