Sunstone provides systems that can spot weld on Cannula thin tubing.
Sample Application of Welding Cannula
The welds in the video were performed with the LZR100 set at 0.7kw power, 0.5ms time, and 0.3mm spot size. Multiple welds were performed along the wire to ensure good hold strength. Adding a small gauge of fill wire to the weld site would allow for higher energy levels to be used and increase the strength of the joint while minimizing the chances of a blow-through.
