New test is carried out in Lantec to consolidate process of laser welding.

First tries are done preparing butt welding tool with good results at 1.2 m/min. However tensile test results are giving low values for the expected target. 

Secondly, overlap (0.3 + 0.3) welding shots are produce, lowering power and using 600 w pulsed power laser. Results as shown in the picture are more likely to be accepted by the customer. Additional challenge is to avoid heat damage on the outer side of the plate. By producing 0.4 mm welds (106 microns spot) and 0.5 mm penetration we see there is a steady process and good tensile resistance goal is achieve.
