摘要： The present invention relates to a T-shaped connection frame for connecting car frames, in which a first member is connected to a second member via a joint member to form a "T." The joint member is formed by symmetrically dividing a rectangular tube between its two latch teeth located at the upper-center and lower-center inner walls. The rectangular tube also has protrusions at the left and right exterior walls. The joint member divided in this way has the latch teeth at the upper and lower tips of the mouth formed by the division and has the protrusion situated opposite the mouth so that the first member can be snapped on easily to this mouth and the second member can be attached to the protrusion at the opposite side. This structural arrangement makes the positioning of the frames very simple, obviates a make-shift attachment, and, at the same time, reduces the number of operation steps.

摘要翻译： 本发明涉及一种用于连接轿厢框架的T形连接框架，其中第一构件经由接头构件连接到第二构件以形成“T.” 接头构件通过将矩形管对称地分配在位于中心中心和下中心内壁的两个闩锁齿之间来形成。 矩形管也在左右外壁上具有突起。 以这种方式分割的接头构件在由分隔开口形成的口的上端和下端处具有锁定齿，并且具有与口相对的突出部，使得第一构件可以容易地卡扣到该口上，并且第二构件可 附着在相对侧的突出部。 这种结构布置使得框架的定位非常简单，避免了换档附件，并且同时减少了操作步骤的数量。

摘要： The first and second weld areas of respective first and second metallic workpieces of aluminum or aluminum alloy are held in abutment against each other with a surface of the second metallic workpiece being positioned on a positioning guide of the first metallic workpiece. A recess is defined between the positioning guide and the second metallic workpiece. A high-density energy beam such as a laser beam is applied to the first and second weld areas thereby to develop a molten pool therein that grows toward the positioning guide until metallic oxide films formed on the first and second metallic workpieces are forced into the recess by the molten pool. As no metallic oxide films are present in a weld joint between the first and second metallic workpieces, the resultant welded structure is of a high mechanical strength.
