Precision welding of challenging alloys
Our welding technology has not only been developed for welding thin structures and materials made of steel and stainless steel, our welding machines also have specially adapted welding curves for welding titanium, aluminum and brass alloys as well as copper.
Our recommendation for challenging welding tasks is the Micro Arc Welderwhich not only offers the most comprehensive selection of preset welding curves, but also the highest power and speed of all Lampert welding machines. This means they are prepared for all challenging alloys, including welding titanium, aluminum, copper, brass and many more.
Titanium is significantly more difficult to weld than steel due to its greater robustness and hardness. In particular, a perfect shielding gas atmosphere and the avoidance of excessive heat are crucial, as titanium quickly absorbs oxygen or nitrogen at higher temperatures during the welding process and which may form embrittlements. Lampert welding devices include a welding curve ideally suited to titanium to overcome these challenges.
The challenges of welding aluminum with regard to oxide formation, embrittlement and high thermal conductivity are widely known. Over many years of development, we have adapted the Lampert welding process to reliably and permanently join thin structures and workpieces made of aluminum alloys with a high aluminum content.
Copper is an excellent heat conductor and therefore requires a sufficiently strong energy input during welding to overcome the dissipation of heat away from the welding point. The strong tendency to oxide formation must also be taken into account, both in general and during the welding process itself. The Lampert welding method takes these circumstances into account in a special copper welding curve that enables the reliable joining of thin copper workpieces.
Welding brass initially presents similar challenges to welding copper due to the high copper content. However, due to the zinc included, the different melting points of copper and zinc can also lead to vaporization of the zinc and to porosity and cracking. Here too, our technology enables us to offer a reliable welding process that overcomes these difficulties and reliably welds thin brass workpieces.
