Laser Welding Help

(OP)
I need to laser weld a 304L disk (dia.480x .001"thk) to an opening in a 17-4PH body to create a sealed port.  I am not familiar with laser welding at all (new industry for me).  Do I have to worry about warping or other positional issues such as work holding?.

RE: Laser Welding Help

You should consult with the welder how to machine and prepare the opening such that it will fix the disc in place. I am not sure that the 0.001" is not too thin for laser weld but I think that the Micro TIG can do it.

Sorry, that was a typo, it should be .011"thk.  The disk fits into a counterbored area like a spotface.  I had originally thought TIG as well, but was told to laser weld it.

RE: Laser Welding Help

I meant Micro TIG not TIG. A company I worked for ordered custom design miniature sealed bellow (~1/2" dia) made by Micro TIG of many beveled disks ~0.1-0.2 mm thick.

RE: Laser Welding Help

We used laser welding to weld the bellow to a solid tube.
