Andy Toms, director at TLM Laser, discusses the benefits that pulsed lasers bring to welding and joining applications within medical device manufacturing. When it comes to welding and joining metal components, lasers offer distinct advantages over other more traditional processes such as TIG (tungsten inert gas) or micro TIG welding, however those considering laser technology have yet another choice to make, a decision between a CW (continuous wave) laser or a pulsed laser. Manufacturing processes continue to evolve year on year and as a result, we generally see the introduction of a new technology or process being adopted by forward thinking manufacturing sectors, before the technology becomes mainstream as others realise the benefits it can bring. This scenario is certainly true of the original transition from conventional TIG and Micro TIG welding to that of laser by medical device manufacturers. Laser welding offered a wide range of benefits including greater precision, and by comparison, a much-reduced heat affected zone, and the fact that the process could be performed with more consistency with less skilled operatives. Today manufacturers have another choice, that of adop...
