Micro mode helps with delicate tasks, enabling microwelding
on sheet metal as thin as 0.
Techniques in Braze Set-Up Operations
Among the topics are challenges in manufacturing from the mesoscopic to nanoscopic scales, microgrinding, magnetorheological and allied finished processes, laser microwelding
, dimensional metrology for microscale and mesoscale manufacturing, and an integrated wafer surface evolution model for chemical mechanical planarization.
Veslatec Oy (Vaasa) is a subcontractor in fine mechanics offering precision and microwelding
, as well as cutting and drilling, mainly using Nd:YAG pulsed laser technology.
This work developed and verified models to account for varying temperature conditions during squeeze flow and intermolecular diffusion for thermoplastic microwelding
For instance, Potomac Photonics in Lanham, MD recently added microwelding
capabilities to its portfolio so that it can make full devices, further simplifying its customers' supply chains.
A few of the specific topics examined include microstructural characterization of eutectic Sn-Au solder as a lead-free solution, designing sealing glasses for solid oxide fuel cells, resistance microwelding
of fine nickel wires, and YAG laser and TIG arc welding phenomena.
By using balls manufactured from silicon nitride instead of tool steel, microwelding
in the ball nut is eliminated.

Coherent says its high-power F-Package Diode Laser System was selected for Ohio State University's microwelding
research because it reportedly offers the highest degree of brightness available in fiber-coupled turnkey laser systems.
