WELD LASER CLEANING
Weld preparation is a crucial step before actually placing a weld and can be done with surface cleaning.
Laser cleaning on mild steel welds is challenging, because of the thick, black ‘slack’ that is formed during the welding process, but on small surfaces, it works without any problems.
On the left side of the picture you can see a lower porosity as a result of good surface cleaning. The less porosity in a weld, the less chance it will break over time.
High speeds can be reached when preparing and cleaning the welds on aluminium, which makes laser cleaning a very effective solution.
These speeds match up to common welding speeds, so it is easy to include a new laser cleaning system in an existing line.
Needless to say is the fact that it is a very clean method, in comparison to traditional techniques as for example the use of chemical solvents.
