摘要

本研究利用高光束质量光纤耦合二极管激光器对 10 毫米厚的 Inconel 617 超耐热合金进行了有效的单道焊接。系统研究并优化了聚焦距离和焊接速度等关键参数对焊接特性的影响。在功率密度为 ≈106 W/cm2 的最佳工艺条件下，获得了无裂纹的全熔透焊缝，且变形、气孔和未填充/未切割/根部凸起缺陷最小，接头效率达到 97%-99% 。所产生的焊缝质量与采用传统激光和先进激光混合焊接技术的多通道焊缝质量相当，足以应用于火力发电厂、造船和重工业的各种场合。

High-power fiber-coupled diode laser welding of 10-mm thick Inconel 617 superalloy

In the present study, a high beam quality fiber-coupled diode laser was effectively utilized to weld 10-mm thick Inconel 617 superalloy in single pass. Influence of critical parameters of focusing distance and welding speed on weld characteristics was systematically investigated and optimized. At optimum process conditions with the power density of ≈106 W/cm2, crack-free full-penetration weld with minimal distortion, porosity, and no underfill/undercut/root-hump defects were obtained with 97%–99% joint efficiency. The weld joint quality produced was on par with multipass employing conventional lasers and advanced laser-hybrid welding techniques and sufficient enough to apply in various applications of thermal power plants, ship building, and heavy industries.
