摘要： A method for joining a first part formed of an aluminum material to a second part formed of a steel material by metal inert gas welding and cold metal transfer is provided. An aluminum filler material forms a fillet joint between the parts and provides a structure for automotive body applications, such an aluminum bumper extrusion joined to a steel crush box connection. The first part includes a notch for hiding the start and end of the joint. A transition plate formed of a mixture of aluminum material and steel material can be disposed between the first part and the second part to provide the notch. The second part can include a mechanical fastener further joining the parts together. In another embodiment, the second part includes a plurality of dimples and is welded to the first part along the dimples.

摘要： There is disclosed a method of laser welding a number of coated metal sheets including the steps of: providing the coated sheets to be joined, and creating a raised region on at least one of the coated sheets. The raised region is formed on a first surface of the metal sheet while the second opposite surface of the sheet remains continuous and uninterrupted. A laser is then applied forming a weld joint where gases produced during the forming of the laser weld escape via the at least one embossment. In an alternative embodiment fine particles may be distributed on the surface of one or both of the sheets of coated metal to introduce a gap for the gases produced during the forming of the laser weld a place to escape. Preferably the fine particles will be zinc dust to maintain the coating between the two sheets to be joined.
摘要翻译：公开了一种激光焊接多个涂覆金属板的方法，包括以下步骤：提供待接合的涂覆板，并在至少一个涂覆板上形成凸起区域。凸起区域形成在金属片的第一表面上，而片材的第二相反表面保持连续且不间断。然后施加激光以形成焊接接头，其中在激光焊接的成形期间产生的气体经由至少一个凸起逸出。在一个替代实施例中，细颗粒可以分布在一片或两片涂覆金属的表面上，以引入在形成激光焊接期间产生的气体的间隙以逸出。优选地，细颗粒将是锌粉以保持待接合的两片之间的涂层。

摘要： A welding tip (20) for spot welding a first part (22) formed of conductive metal, for example aluminum, to a second part (24) formed of aluminum or another conductive metal, such as steel, is provided. The welding tip (20) includes a notch (30) at a distal end (38) and a convex contact surface (28) extending radially outwardly and upwardly from the notch (30) for engaging a surface of the first part (22). The rotating welding tip (20) forms a depression (32) on the surface of the first part (22) during the welding process. The notch (30) creates a pin (34) in the center of the depression (32) which provides a fixed axis of rotation for the rotating welding tip (20) and prevents the welding tip (20) from moving radially relative to the fixed axis, thereby improving the quality of the final spot weld (36) and reducing process time.
摘要翻译：提供了用于将由导电金属（例如铝）形成的第一部分（22）点焊到由铝或另一种导电金属（例如钢）形成的第二部分（24）的焊接尖端（20）。焊嘴（20）包括在远端（38）处的凹口（30）和从凹口（30）径向向外和向上延伸的凸接触表面（28），用于接合第一部分（22）的表面。旋转焊嘴（20）在焊接过程中在第一部分（22）的表面上形成凹陷（32）。切口（30）在凹部（32）的中心形成一个销（34），该销（34）为旋转的焊接尖端（20）提供固定的旋转轴线，并防止焊接尖端（20）相对于固定的轴，从而提高最终点焊质量（36），缩短加工时间。
