汽车双向筒式减震器储油缸筒的激光焊接

Laser Welding for Storage-oil Tube of Two-way Telescopic Shock Absorber in Automobile

介绍了减震器储油缸筒的激光焊接试验过程 ,通过试验研究确定了最佳激光焊接工艺参数。分析了激光功率、焊接速度、激光焦点位置及等离子控制对缸筒的气密性、焊缝拉伸抗力、焊缝形貌、金相组织、硬度分布的影响。

The main technological parameters of laser welding of storage-oil tube are studied systemically in this paper,the effects of laser power, welding speed,focus place,and plasma control on the airtightness,welding strength, welding shape,metallographic structure and hardness distribution are analyzed too.
