Today lean thinking has led many to consider not just manufacturing costs, but also the costs that occur over the entire product life cycle. This is where hybrid laser-arc welding has really stepped up to the plate—literally. The technology can be used to weld high-strength steel parts effectively, which is great news for the transportation industry as they look to reduce the weight of components.
As the move toward part miniaturization continues, more and more companies are turning to microwelding for the precision joining of copper and other highly reflective materials, in particular, employing laser welding with a green wavelength.
