中文摘要 | 本研究利用半自動氣體鴿極電弧銲接機 (GTAW) 表面重熔球墨鑄鐵 (ductile iron) 材料,將鑄態材料作不加料之重熔處理後,探討銲接參數對球墨鑄鐵重熔後之機械性質變化與相變態之相關機制。並利用電腦模擬 "Rosenthal's analytical solution for three-dimensional heat flow during welding" 來探討銲接參數對球墨鑄鐵表面重熔之影響,以瞭解材料予何種銲接條件下,能夠得到最佳品質之銲道。最後並將實際實驗值以電腦模擬方式來探討銲道內之熱傳過程與溫度分佈問題。 |
英文摘要 | Surface remelt of welding the as-cast ductile iron by using of the semi-automatic gas tungsten arc-welding (GTAW) machine in different energy input. Phase transformation and mechanical properties changing for weldment of ductile iron were observed and analyzes mutually in fusion zone and heat affected zone in matrix. Comput model of the ductile iron welding bead of thermal cycles, isotherms, and peak temperature locus for the influence of the welding parameters will upon the welding heat input. This governing equation is base on the "Rosenthal's analytical solution for three-dimensional heat flow during welding" to model the bead thermal distribution. Moreover, comparing the experimental data and the value of computer modeling welding bead results physically, to inquire heat input the welding bead conductivity and temperature distribution of the problem. |
