Strength of Laser Weld

Strength of Laser Weld

Strength of Laser Weld

(OP)
Hi,
  I would like to know if there is any documentation on the strength of laser weld. Is it about 80% of the material strength?

Regards.

RE: Strength of Laser Weld

You would get a lot from "Welding Metalurgy" by Sindo Kou.  It was published in 1987 by Wiley & Sons.   A properly spec'd fusion weld in weldable material should usually produce a weld that exceeds the tensile strength of the parent material.  Remember to minimize the heat affected zone.  Hopefully you're using a constant wave "keyholing" process with a high weld velocity.

Happy Reading
