anyone have experience with laser welding?

admin

I do a lot of laser welding in my line of work. I did a lot welding for fabrication for car stuff in my garage so i took the lead as "they guy" for a all of the welding processes at work. I do a lot of resistance, parallel gap, ultrasonic, and impulse welding.Anyway, a fellow engineer originally designed some hardware to be tigged on a rotary table with pulse and settled with 316L. It was later determined that it was too much heat for the components so we had to laser weld the parts. Unfortunately i never had good experiences with 316L using a yag laser unless the fitment was ultra perfect. I'm talking about a 0 gap press fit. spot size is about 25mils. you can see some of the heat cracks. Mostly due to a poor choice in material for the application. Next time he will know to consult in me before material selection. I will have to go back to tigging the parts after machining some hefty heat sinks. just thought i would share.
