Welding in metal construction
Are you looking for reliable and precise joining technology for your metal construction projects? The micro TIG welding process from Lampert offers you the flexibility and precision you need and enables you to weld thinner material thicknesses between 0.1 mm and 1.0 mm without any problems. Discover the many possibilities that our precision welding machines for metal construction open up for you and expand your range of welding to include thin materials and structures.
Welding thin pipes and profiles
Tubes and profiles with a material thickness of 1.0 mm are very challenging to weld, material thicknesses of less than 0.5 mm are often considered impossible to weld. Lampert welding technology provides a remedy here. Our micro TIG welding process can weld even the thinnest material thicknesses without any problems and without any distortion. Thin tubes and profiles can be welded perfectly and without subsequent reworking.
In series production, the challenge often arises of fixing workpieces sufficiently before further processing, e.g. in the brazing furnace, to ensure a clean brazed joint. In this application, we will show you how this is possible in the case of pipe connections, which can be tack-welded with a few spot welds before the brazing process and thus fixed in the correct position.
Seal welding stainless steel
Welding thin materials in a liquid and gas-tight manner is often a challenge, as imperfections in the weld seam must be absolutely avoided. Lampert welding machines are often used to weld containers in medical technology, pipes for gas mixtures in research and also hydraulic tanks in model making. With the correct parameter setting, our welding machines can handle the leak welding of your workpieces with ease.
Welding thin pipe with miter joints
With Lampert welding technology, it is easy to produce 90° angles from thin metal tubes. In this case, a stainless steel pipe with a wall thickness of 0.5 mm was welded, but pipes or profiles made of other alloys (e.g. brass, copper) or thinner material thicknesses of up to 0.2 mm are also no problem for our welding equipment. If needed, the connection can be made gas and liquid-tight too.
Welding shape memory alloys (memory metals)
The Lampert welding process also enables the welding of shape memory alloys, so-called memory metals, thanks to its locally limited heat input. Such alloys usually consist of nickel-titanium (NiTi) or nickel-titanium-copper and remember their original shape, to which they return even after mechanical deformation. As excessive heat input would impair their function, memory metals are often clamped, riveted or crimped. With a Lampert welding device, you can also reliably weld your memory metal parts without impairing their function. The application shows the two welded ends of two NiTi spring parts.
Weld cooling fins onto pipe
Do you use tanks and pipes for special heating and cooling systems and need cooling fins that are directly connected to the piping? Our welding process enables the cooling fins to be welded directly onto the pipe to ensure optimum heat dissipation. Soldering is no longer necessary, all you need is a Micro Arc Welder and a suitable eye protection system.
Welding advertising signs and building lettering
Three-dimensional letters for lettering and advertising on buildings are usually made of metal due to their greater durability. They are almost exclusively produced individually or in small batches. Soldering, gluing or welding are generally used as joining techniques. Adhesives are very often not durable if they are continuously exposed to the weather, soldered signs and letters can come loose again if the temperature on the building façade is elevated by direct sunlight over a longer period of time.
A permanent connection can only be ensured by welding the individual parts together. Lampert’s micro TIG welding technology has proven to be ideal in order to avoid damaging the thin sheet metal of the signs and letters during welding and still ensure a form-fit connection. The letters in the specific application are only tacked with individual welding points at the seam. Alternatively, a continuous weld seam is of course also possible.
The best thing about it: the welding points are not visible on the front of the letters. The surface remains flawless and can be perfectly highlighted with direct and indirect lighting. Coating and painting is also possible without any special reworking thanks to the distortion-free welding and the low heat-affected zone.
Welding metal railings directly on the construction site
Metal railings and metal frames are normally welded in the factory and then simply assembled on site. With Lampert micro TIG welding technology, both are possible, including the complete joining of individual parts directly at the assembly site. Reworking is also no problem. All that is needed is a Micro Arc Welder with a Precisionmaxx welding helmet.
The visual appearance of a micro TIG weld seam is still unsurpassed and can otherwise only be achieved with an expensive laser welding system. This, in turn, is not nearly as mobile as the Lampert welding machines.
The perfect requirement profile for micro TIG welding technology is to produce perfect weld seams with a flawless appearance anywhere, easily and without great effort. Welding training is not required due to the simple handling. The result speaks for itself.
