Novel laser welding methods for energy and transportation

滑铁卢大学和CanmetMATERIALS的合作将评估最先进的激光焊接技术，并为管线钢和不同材料的先进激光焊接开发新方法。将研究两个特殊的应用领域：管道厚截面钢焊接，以及用于运输结构的异种铝钢焊接。一种新的最先进的混合激光焊接将用于优化和确定厚板钢板和薄板异种连接的热丝和多丝进给、光束振荡和激光深度动态传感等技术的优势。实施这些技术和优化其参数的细节将有助于各行业在现场采用这些技术，并将有关加工和材料性能的结果传播给更广泛的科学界和更广泛的行业。新的数据将提供对这些技术能力的公正评估，帮助培训新的工程师在外地实施这些技术。

This partnership between the University of Waterloo and CanmetMATERIALS will evaluate the state-of-the-art laser welding technologies and develop new methods for advanced laser welding of pipeline steels and dissimilar materials. Two particular application areas will be studied: pipeline thick-section steel welds, and dissimilar aluminum to steel welds for transportation structures. A new state-of-the-art hybrid laser welding will be used to optimize and determine the advantages of technologies such as hot-wire and multi-wire feeding, beam oscillation, and laser depth dynamic sensing for both thick-plate steel and thin-sheet dissimilar joining. The details of implementing these technologies and optimizing their parameters will help industries to adopt them in the field, with results being disseminated about the processing and material performance to the broader scientific community and broader industry. New data will provide and unbiased assessment of the capabilities of these technologies, help train new engineers to implement these technologies in the field.
