本文用特殊化学处理办法,首次真实、完整地揭示了各种压焊接头界面的自然形貌,直接观察不同压焊方法的工艺特征和不同金属相焊的界面形态,为研究金属压焊机理、分析压焊过程及工艺质量开辟新的途径,避免了通常由接头侧面观察、分析的局限性。这一新技术较方便地展示出各种压焊接头界面形貌与其工艺特征的关系。
In this paper, for the first time, the natural morphology of the interface of various press welded joints is revealed for the first time in a real and complete way. The process characteristics of different press welding methods and the interface morphology of different metal welding are directly observed. In order to study the mechanism of metal press welding , Analysis of pressure welding process and process quality to open up new avenues, to avoid the side usually from the joint observation, analysis of the limitations. This new technology is more convenient to demonstrate the various pressure welding joint interface morphology and process characteristics of the relationship.
