Ti metal is in a class of all its own. Cannot be compared to Chrome cobalt, gold, etc. Temp settings will differ due
to Ti can be welded at a much lower heat.
Argon is a must as mentioned above. Also when prepping your metal to weld,
normally a rubber wheel is used, not a burr. You want a smooth surface,and once again be careful not to overheat the metal.
Not familiar with that welder " Elettrolaser" for pulse shaping. There are different ways to apply the heat source. Some have
a "Duty" that is main power that can be reduced, but increased on the other end to create a more pin point laser. That normally
is used in tight areas around abutments for example. As AJEL mentioned above. Once you can weld two pieces together,
bend them with pliers and not break, you have it mastered. Also practice with a study cast with implant analogs. Start your weld at
a corner with a tack weld then rotating it 180 degrees, until all four corners are connected. Then proceed with a full bead weld over lapping
your welds. Do not try to build up the metal in bulk as it will create a weaker joint.
There is a demo on my website (
www.hawkeyedentalstudio.com) in the services section of two pieces of stainless metal being welded.
Joint is very wide, but using the correct parameters it allows the laser to fully capture both sides of the metal to create a strong weld joint.
Just takes some seat time and alot of practice.
Check out BTI, they have an excellent training facility in Uticia, New York.
