锆合金格架外条带激光焊接工艺研究

Research on the Laser Welding Process of Zirconium Alloy Grid Outer Strap

论文通过激光焊接试验进行格架外条带焊接工艺研究,并依据熔深和表面质量进行焊接质量评估,最终得出如下结论:峰值功率和频率对焊接熔深影响较大,随着峰值功率和频率的增加,格架外条带焊接熔深先增大后减小;峰值功率对表面质量影响较大,随着峰值功率的增加,氧化色渐重,但频率对氧化色影响较小。

Through the laser welding test,the paper studies the welding process of the grid outer strip,and evaluates the welding quality according to the penetration and surface quality.Finally,the following conclusions are drawn:the peak power and frequency have great influence on the welding penetration.With the increase of the peak power and frequency,the welding penetration of the grid outer strip first increases and then decreases.The peak power has a great influence on the surface quality,and the peak power has a great influence on the surface quality.With the increase of the power,the oxidation color becomes heavier,but the frequency has little influence on the oxidation color.
