Weld Cleaning
WELD LASER CLEANING
STEEL
Weld preparation and weld cleaning are vital in the steel processing industry. A laser system can effortlessly be built into an existing process or production line, speeding up the complete process.
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.

ALUMINIUM
The effects of good weld preparation were determined with an investigation we did on aluminium a few years ago. We compared good and bad weld preparation, meaning all oxides were eliminated via surface cleaning on one part, and no cleaning was performed on another one.
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.

STAINLESS STEEL
Stainless steel is as suitable for weld preparation and cleaning as aluminium. You can reach cleaning speeds varying from 1m to 1.5m per second.
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.
