摘要

为解决传统电弧螺柱焊焊接大直径（M≥12 mm）有色金属时焊缝合格率低、焊接工艺繁琐等问题，提出采用静龙门式搅拌摩擦焊设备配合专用螺柱焊工装对尺寸为M12、材质为TA2的工业纯钛螺柱与底板进行焊接。并对三组不同顶锻位移下的工业纯钛螺柱焊接头进行宏观形貌、显微组织、抗扭强度与显微硬度分析。结果表明，在顶锻位移较小的情况下，TA2螺柱焊接头焊缝中心出现孔洞缺陷，顶锻位移中等的情况下焊缝中心出现条状缺陷，而较大参数下接头焊合良好，未发现缺陷；顶锻位移为3 mm时接头抗扭强度最高，可达117 N·m；锻造变形组织使焊缝附近区域显微硬度明显升高。

Abstract

Aiming to solve the problems such as low weld pass rate and complicated welding process when welding non-ferrous metal with large diameter (M≥12 mm) in traditional arc stud welding, the static gantry friction stir welding equipment with special stud welding fixture was used to realize the industrial pure titanium（TA2）stud welding with size M12. The macroscopic morphology, microstructure, torsional strength and microhardness of joints were analyzed under different forging displacement and forging speed. The results show that when the forging displacement is small, the hole defect appears in the center of the welding joint, and when the forging displacement is medium, the strip defect appears in the center of the welding joint, while the joint is well welded and no defect is found in the larger parameters. When the top forging displacement is 3 mm, the joint's torsional strength reaches 117 N·m. The microhardness of the area near the weld is obviously increased by forging deformation.The microhardness near the welding joint is obviously increased by forging deformation.
