This reduces probability of pore formation to a non-detectable level. In addition, the risk of hot cracks is minimized as well. The possible penetration depth can be nearly doubled with the same beam power. With this deep penetration, the weld seams can be as narrow as in electron beam welding.<\/li>\n<\/ul>\n<p><!-- \/wp:list --><\/p>\n<p><!-- wp:list --><\/p>\n<ul>\n<li>Particularly clean process environment:<br \/>Welding spatter minized or avoided in vacuum conditions. Due to that, potentially no post-weld treatment or post-processing cleaning is necessary, which saves additional processing steps and production time.<\/li>\n<\/ul>\n<div>\u00a0<\/div>\n<ul>\n<li>Welding of oxygen affine metals such as tungsten or titanium:<br \/>Virtually no shielding gas is necessary for welding. This avoids consumables e.g. argon gas, etc.<\/li>\n<\/ul>\n<p><!-- \/wp:list --><\/p>\n<p><!-- wp:list --><\/p>\n<ul>\n<li>Resilience towards magnetism:<br \/>The laser beam consists of photons and can therefore also weld magnetic materials. Magnetic clamping devices for fixing and positioning the workpieces in the process chamber can be applied. Demagnetization of the workpiece prior to the laser welding is unnecessary which reduces the cycle time and shortens the process chain. Even inductive heating is possible during the welding process.<\/li>\n<\/ul>\n<div>\u00a0<\/div>\n<ul>\n<li>No hazards by X-rays:<br \/>The generation of the laser beam does not generate X-rays. An all-metal vacuum chamber already provides sufficient protection against laser reflections.<\/li>\n<\/ul>\n<div>\u00a0<\/div>\n<ul>\n<li>No filler material needed:<br \/>Similar to EBW (Electron Beam Welding), joining metals and alloys requires no filler material as opposed to arc welding.<\/li>\n<\/ul>\n<p><!-- \/wp:list --><\/p>\n<p><!-- wp:list --><\/p>\n<ul>\n<li>Fully automated welding:<br \/>Fully automated laser beam welders enable extremely precise repeatability and full traceability of relevant welding parameters during the weld itself per workpiece. So, the welding process of each item can be securely controlled and documented. This is essential for validated processes as for example in aerospace industry. This does not only apply for the production of original equipment for aviation and space crafts, but as well as for the MRO operations (Maintenance, Repair, Overhaul). Welding with the laser in vacuum facilitates the repair process due to extremely low heat input and low distortion of the component, while supplying exceptional weld strength.<\/li>\n<\/ul>\n<div>\u00a0<\/div>\n<ul>\n<li>Vacuum chambers available in different sizes:<br \/>The vacuum chamber size of Evobeam laser in vacuum (LaVa) welding machines are adapted to the specific application requirements in order to minimize volume and, thus, evacuation times. This significantly reduces the overall cycle time for welding and improving overall productivity.<\/li>\n<\/ul>\n<p><!-- \/wp:list --><\/p>\n<p><!-- wp:list --><\/p>\n<ul>\n<li>Diode laser source:<br \/>Diode fiber laser as source efficiently generate a laser beam.
