Abstract

Design and fabrication of a weld protection drag-cover has been discussed in the paper as using high-power CO₂ laser to weld Ti6A14V in various thickness. Argon was used to protect the weld and its nearby region from contamination from hydrogen, oxygen and nitrogen as their temperature were higher than 300 degrees Celsius. The protection effect has been proven to be good, since the weld surface was smooth, the obverse side appeared silvery white, and the reverse side appeared light-yellow.
