Fiber Lasers for Trifocal Brazing and Welding

To obtain high-quality brazed joints, the base metals must be clean and free of oxides. Contamination can cause poor wetting of brazed parts impeding flow of the filler material, compromising the strength and visual appearance of the joint.

In trifocal laser brazing the main laser spot is accompanied by two smaller ablation spots that are offset laterally and precede the main spot in the brazing direction. The localized heating of ablation spots allows cleaning of the base metal parts improving filler material flow, resulting in reproducible brazed joint with increased strength and better appearance.
