The beam waist means the ‘portion of a beam where the beam diameter or beam width has a local minimum’.[ISO 11145:2018, Optics and photonics — Lasers and laser-related equipment — Vocabulary and symbols]
The beam waist is thus the most energetic area of the laser beam and the place where the welding process is carried out. We also feed the 3 partial laser beams into our beam waist to melt the welding wire evenly.Similar term: build up [ISO/TR 25901-1]
Building up means ‘overlay welding to obtain or restore required dimensions’.[ISO/TR 25901-1:2016-03, Welding and allied processes — Vocabulary — Part 1: General terms]
The wire material is used for the building up. The terms building up and surfacing are used in a similar way.
