摩擦攪拌銲接之攪拌桿探針與銲接參數選擇易產生問題,導致攪拌桿壽命及摩擦攪拌銲接銲塊品質優劣受到影響,所以本研究擬研究摩擦攪拌銲接攪拌桿探針設計最佳化。實驗材料以AZ61鎂合金和AZ80鎂合金為主,探討攪拌桿探針設計和材質對摩擦攪拌銲接之影響。以攪拌桿探針的外觀和重量之變化、黏著及去除材料之難易以及磨耗,尋求最佳攪拌桿探針設計和壽命。實驗的攪拌桿參數有圓柱形狀、錐度形狀、螺紋形狀、不同材質,加上摩擦攪拌銲接參數的旋轉速度、進給率、攪拌桿傾斜角度等對攪拌桿壽命之影響,並比較不同鎂合金對攪拌桿壽命之影響。
摩擦攪拌銲接與傳統銲接比較,雖其銲接後之銲件機械性質有明顯提昇,但仍有缺陷產生,幾乎是來自於銲塊組織中的孔洞及銲後效果,而攪拌後黏著材料即材料損失,代表試片重量相對的損失,本研究發現經摩擦攪拌銲接之材料損失與銲塊缺陷和機械性質非常密切關連,而材料損失來自於攪拌桿探針上黏著材料、試片毛邊溢出料,和摩擦攪拌銲接過程產生的微屑,在整個研究中,發現攪拌桿探針最好的設計為螺紋探針。
關鍵字:摩擦攪拌銲接,攪拌桿,鎂合金
Easily it will have problem between the tool probe of friction stir welding and welding parameter, leading to the affection, depending on the quality of tool life and friction stir welding nugget. The reason of this simulated experiment shows that this research is on optimal design of tool probe for friction stir welding. AZ61 Magnesium alloy and the AZ80 Magnesium are used as first priority of searching material in this experiment, which can let us get the thought of the tool probe design and the influence of friction stir welding on materials Observing the tool probe, which surface change, weight change, and adhesion force character are regarded as design considerations in search of the best design of tool probe and improving tool life is needed. In this experiment, basically there are cylindrical shape, taper shape, screw shape with different materials Besides it may have affection based on rotation speed, feed rate, tool tilt angle, and the parameter of Friction Stir Welding. Furthermore, it will have the differences compared with magnesium alloy.
The comparison between friction stir welding and tradition weld has different viewpoints, even through there is obvious improvement after finishing welding process, still has some drawbacks. Moreover the reason why it will have this result depending on he hole in the organization of weld nugget and the post-weld heat treatment [PWHT].After this process, there will be material losses after stirring, which means experiment sample also has this issue. From this research, we find there is a big connection among stirring material loss, weld drawback, and mechanical character. In addition, and the material loss comes from the stuff stuck on the tool probe, sample Fur side spillage, and the Fur Weight Disappearance under the Friction Stir Welding process. In the whole Study, we can find out the best design decision is screw probe in stirring procedure。
