A constant challenge in laser processing--both now and in the future--"is defining the line between what is feasible and what is not feasible," said Chandler Newcomb, sales and marketing representative for Laser Dynamics, a Hutchinson, Minn.-based contract laser materials processing company specializing in laser marking, laser micromachining, and laser microwelding. "As parts become smaller and require tighter tolerances, it is often difficult to determine their feasibility without running tests first.
We will develop new ultrafast laser processes for dissimilar material joining (microwelding) and also design and build a flexible custom laser prototype machine capable of applications development to demonstrate such laser microwelding in key selected real devices at TRL level 6.

The lack of an oil film, Kollin says, causes microwelding or microscuffing that begins with minor pitting.
Topics covered include microwelding, effects of sterilization, memory alloys, platinum, alloys, stainless steel wire, and methods for evaluating corrosion performance of welds.
Micro mode helps with delicate tasks, enabling microwelding on sheet metal as thin as 0.10 mm.
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. In this case, temperature history fields were predicted using moving heat source models, and these temperature histories were used to predict the size of laser microwelds.
Microwelding provides the medical device industry with yet another option manufacturing solution that enables OEMs to achieve further miniaturization of their products.
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.
