Aluminum welding requires a great deal of expertise, many years of experience and a sure instinct to ensure consistently high quality. In recent years, a wide variety of welding processes have developed solutions to meet the special challenges of this material.
At TM Lasertechnik, we have been focusing primarily on laser and laser hybrid welding in aluminum welding for 20 years. We use welding sources that allow us to control the process very well.
By constantly developing and striving to find answers, we are able to successfully process aluminum alloys that are generally considered to be unweldable to a high quality.
Individually tailored to the project, we weld manually, partially or fully automated (CNC-controlled) using laser or laser hybrid processes.
We perform fine welding in the range down to 0.3 millimeters.
With us, you get everything from a single source: we are happy to offer finishing work such as turning, milling or grinding on request.

Aluminum is a material that has high strength at low weight / low density. In addition, it reacts with its ambient air, forming a layer of aluminum oxide that protects the material from corrosion, oxygen and many chemicals.
This oxide layer has a melting point of 2050° C, but the aluminum itself melts at only about 660° C.
This is what makes aluminum welding so difficult.
When welding aluminum, the protective layer must first be removed, observing the strictest cleanliness measures. Alternatively, it is broken through with very high energy input during welding.
Due to the different melting temperatures, however, the aluminum component loses its stability on the inside and is in danger of literally melting. The boundary between loss of stability and a weldable melt is very narrow.
Maintaining this balance is our know-how.
