The proposed collaborative research and development project between the University of Waterloo, ArcelorMittal Dofasco, a producer of automotive steel products, and Zelixir Inc., an organization dedicated to the interest of zinc and its users, aims to investigate the effects of Zn and Al-Si coatings on the weldability of advanced high strength steel (AHSS). The coatings behavior and its effects on weld microstructure during resistance spot welding (RSW) and laser welding will be correlated with the mechanical performance of the joints under static and dynamic loading conditions. The focus will be towards liquid metal embrittlement (LME) due to Zn coating and fusion zone softening due to Al-Si coating during welding of AHSS. The investigation will provide a guideline for mitigation and remediation of LME cracks in Zn coated and fusion zone softening in Al-Si coated AHSS during welding. Moreover, the project will increase knowledge of coating and substrate reaction during welding. The results of the study will be beneficial to the Canadian manufacturing sectors in general, and will specifically contribute significantly to the steel and automotive industries. Training of highly qualified personnel (HQP) will assist in fostering talent in the manufacturing industry and simultaneously strengthen the reputation of the University Waterloo as a world-renown research institution.

拟议的合作研究与开发项目，滑铁卢大学，汽车钢铁产品生产商Arcelormittal Dofasco和致力于锌及其用户利益的组织Zelixir Inc.旨在研究Zn和Al-Si涂料对高级强度钢（AHSS）的效果。在电阻点焊接（RSW）和激光焊接过程中，涂料行为及其对焊接微结构的影响将与静态和动态载荷条件下关节的机械性能相关。由于Zn涂层和融合区域软化，由于AHSS焊接期间的Al-Si涂层，其重点将用于液态金属含量（LME）。该调查将为焊接期间的Zn涂层AHS中的Zn涂层和融合带软化的LME裂纹提供指南。此外，该项目将增加对焊接过程中涂层和底物反应的了解。这项研究的结果将对加拿大制造业一般是有益的，并将特别为钢铁和汽车行业做出重大贡献。对高素质人员（HQP）的培训将有助于培养制造业的人才，并同时增强滑铁卢大学作为世界著名的研究机构的声誉。
