The history of joining metals goes back several millennia, called forge welding, with the earliest examples of welding from the Bronze Age and the Iron Age in Europe and the Middle East. Since these early stages lots of inventions, process improvements and completely new welding techniques have been created. Nowadays entire industries rely on the various welding processes to manufacture high-quality joints. Especially high-performance materials used in aerospace and medical applications such as titanium or magnesium are difficult to weld as they oxidize easily and become brittle. Processes that employ inert shielding gases to protect the weld try to suppress these unwanted oxides but still lack in quality because of unpredictable atmospheric movements are enough to result in a faulty weld.
Furthermore welders are often exposed to dangerous gases and particulate matter. Processes like flux-cored arc welding and shielded metal arc welding produce smoke containing particles of various types of oxides which affect especially the lungs. The size of the particles in question tends to influence the toxicity of the fumes, with smaller particles presenting a greater danger. Another danger stems from the use of compressed gases and flames in many welding processes as they pose an explosion and fire risk. Some common precautions include limiting the amount of oxygen in the air, and keeping combustible materials away from the workplace.
I've been a precision welding specialist for 20 years and found the construction quality of our equipment to be excellent.

MBRAUN's welding solutions address all these problems by enclosing
the welding process in a controlled environment. This approach allows highly reproducible welding conditions and complete protection of the welder from hazardous fumes whilst preventing any kind of oxidation and therefore brittleness of the weld.
In order to address the various needs small bench top systems such as the MB TIG 1010, particle absorber with continuously active separation, standard and custom antechamber configurations, inert gas purifiers, gas-mixing units and completely customized industrial scale welding systems are available at MBRAUN. All have in common that the welding process takes place under completely inert conditions.
Typical processes which are frequently performed in MBRAUN welding solutions are resistance welding, TIG welding, laser welding and plasma welding. A special application is the fusing of quartz glass during the manufacture of metal halogenated lamps for which MBRAUN offers designated plasma burners. Ranging from single piece manual welding stations up to fully-automated welding solutions with gas-composition recording and treated-part serialization MBRAUN has your specific welding solution.
