What kind of travel speeds are required for a successful keyhole weld?

Travel speeds will vary depending upon the thickness of the material.

Typically, the travel speeds required for a keyhole hole weld range between 200 mm/min | 5.9 in/min for thicker materials through to 800 mm/min | 31.5 in/min for thinner materials.  The exact travel speed required is particular to the weld application.
