Hand-held laser welder devices are being imported into Australia in increasing numbers from a variety of sources. These devices transmit invisible laser light energy via fibre optic cables to a welding torch similar in design to a conventional GMAW or Mig welding torch. They are typically used for the welding of light-gauge sheet metals on a range of materials, some of which are highly reflective. e.g. carbon and stainless steels, titanium and aluminium.
