Abstract

Various joining techniques are consistently used in fabrications and maintenance applications of numerous parts in manufacturing industries. Typically, the friction welding technique acquired attention in joining of aluminum and its different alloys for very general structural usages in small to medium to large-scale manufacturing sectors. This is an experimental attempt to weld aluminum 6061 alloy T6 grade of 3mm thickness metal sheets. The hexagonal-shaped steel pin of grade H13 is used. The experiment is performed by using the Taguchi L9 approach, and nine welded specimens are prepared. The chosen factors are rotating speed of the tool, tilting angle, and feed. After the welding, the tensile testing is followed for the measurement of strength of the welded samples. The analysis suggested that the chosen working limits of feed and rotational speed is significant and having impacts on weld strength. The maximum strength is obtained as 212MPa when the ranges of above said factors are 560RPM, 0degree, and 20mm/min.

利用期望函数最大化6061铝合金T6级摩擦焊接接头抗拉强度

在制造业中，各种连接技术一直用于制造和维护众多零件的应用。典型地，摩擦焊接技术在铝及其不同合金的连接中受到关注，用于小型到中型到大型制造部门的非常普遍的结构用途。这是焊接铝6061合金T6级3mm厚金属板的实验尝试。采用H13级六角形钢销。采用田口L9方法进行实验，制备了9个焊接试样。所选择的因素是刀具的转速、倾斜角度和进给。焊接后进行拉伸试验，测定焊接试样的强度。分析表明，选择的进给和转速的工作极限对焊缝强度有重要影响。在560RPM, 0度，20mm/min的范围内，最大强度为212MPa。
