The lightweight construction of steel structures is often limited by the mechanical properties of the weld metal. The strength values of modern base materials are not achieved in the weld metal. There is a considerable need to develop welding consumables that allow the processing of modern fine-grained structural steels without limiting their potential. The Physical Vapor Deposition (PVD) coating of welding wire electrodes can increase the strength of the weld metal of a Mn4Ni2CrMo welding wire electrode by up to 30%. By using different coating elements, the Hall–Petch relationship can be exploited and such an increase in strength can be achieved. Especially by applying titanium, vanadium, and yttrium coatings, the strength of the weld metal can be increased. Due to a multilayer structure of the coating, the weld metal and the process can be influenced independently of each other. The effects of mono-element coatings and multi-component coatings on the weld metal and the process are discussed. PVD coatings allow welding wire electrodes to be individually adapted to the requirements.

高强度低合金钢填充焊丝表面涂层的开发及其对焊缝金属组织和性能的影响
钢结构的轻质结构通常受到焊接金属的机械性能的限制。在焊接金属中无法实现现代基础材料的强度值。迫切需要开发焊接耗材,以允许在不限制其潜力的情况下加工现代细晶粒结构钢。焊丝电极的物理气相沉积(PVD)涂层可以使Mn4Ni2CrMo焊丝电极的焊接金属强度提高多达30%。通过使用不同的涂层元素,可以利用霍尔与蚀刻的关系,从而实现强度的提高。特别是通过涂覆钛,钒和钇涂层,可以提高焊接金属的强度。由于涂层的多层结构,焊接金属和工艺可以相互独立地影响。讨论了单元素涂层和多组分涂层对焊接金属及其工艺的影响。PVD涂层可使焊丝电极单独适应要求。
