Laser Welding Benefits

Laser Welding

Laser welding is a proven joining method for a variety of today's metals and metal alloys. Various grades of stainless steel, titanium, inconel, and super alloys have been successsfully welded with the laser. Its precision, repeatability, and high process speeds offer a unique alternative to Tungsten Inert Gas (TIG) welding, Electron Beam (EB) welding, resistance welding, brazing, silver soldering, and adhesive bonding. The laser is particularly ideal for high production volumes associated with fully automated or semi-automated tooling applications.

The Process

Laser welding, in its most common form, occurs when the laser is used as an intense energy source to selectively heat materials to a point between their melting and vaporizing temperatures. Once molten, the materials are allowed to alloy and then resolidify in a controlled atmosphere. The result is a reliable, oxide-free weldment.

Unlike many of the other joining processes, the overall size and depth-to-width ratio of the weld nugget can be custom tuned in laser welding. By adjusting various parameters such as the laser energy and focal point position, one can create weld ratios ranging from wide and shallow to narrow and deep. In most cases the part geometry dictates this ratio.
