To guarantee good quality of butt laser welding with filler wire, a gap width detecting sensor and a wire feeding system has been designed.
本文针对高质量板材对接填丝激光焊的需要，设计了对缝间隙宽度检测的传感器与送丝控制系统。
The width and length of feeding can be stepless adjusted accurately, suitable for the arrangement of different mould, with high use-factor of the sheet.
送料宽度和长度均可无级调整，调整准确，能适用不同的模具的排列，材料利用率高。
The width changes little with the change of powder feeding rate and the height increases with the increase of powder feeding rate.
熔覆层的宽度随送粉速率的改变变化不大；熔覆层的高度随送粉速率的增加而增加；
The width changes little with the change of powder feeding rate and the height increases with the increase of powder feeding rate.
