What welding technology is available?
Welding is a joining technique that uses heat, pressure or both to permanently join metal parts together. There are various welding techniques that use different equipment and processes. These are the most common methods:
MAG welding
In MAG welding (metal active gas welding), a wire is continuously inserted into the welding point and coated with a gas mixture. The gas protects the weld seam from contact with air. This process is very fast, distortion is low and the amount of work required after welding is minimal. MAG is therefore particularly suitable for welding steel and stainless steel together in large quantities.
MIG welding
MIG welding (metal inert gas welding) also uses a wire electrode, but a pure shielding gas such as argon or helium is used. This prevents the welding point from oxidizing during melting, resulting in particularly clean seams. MIG is stable and can be easily automated. It is therefore ideal for stainless steels and aluminum in modern production lines.
TIG welding
In TIG welding (tungsten inert gas welding), a solid tungsten electrode serves as the arc source, while inert gas provides protection. Because no welding wire melts, there is almost no spatter and very fine seams are created. TIG is perfect for thin sheets and components made of stainless steel or aluminum, such as those used in medical technology or pipeline construction.
Plasma welding
Plasma welding is similar to TIG welding, but works with a concentrated plasma arc. This is created by passing a gas - usually argon - through a narrow nozzle and ionizing it with an arc. This creates an extremely hot and stable plasma jet that hits the workpiece with pinpoint accuracy. The process is perfect for narrow and deep weld seams with minimal heat input and demanding applications. It stands for the highest seam quality with low deformation.
Laser welding
In this innovative welding process, a focused laser beam fuses the workpieces with pinpoint accuracy - without any direct contact. The heat-affected zone is very small, which means that the area surrounding the welding spot is hardly heated at all. This makes extremely precise welding possible, resulting in very thin weld seams. Laser welding is usually used when high speed and low distortion are required - especially for assemblies and series production.
Welded constructions and welded assemblies
Schnelldorfer Maschinenbau develops and manufactures customized welded constructions and assemblies that are precisely tailored to your production processes. Whether individual modules or complete system solutions - our modular approach offers maximum flexibility and efficient series production. You benefit from solutions that can be perfectly integrated and adapted.
-
Customized welding assemblies
Based on your drawings and parts lists, our welding engineers design individual assemblies made of steel, stainless steel or aluminum. The use of materials, clamping fixtures and welding strategy are optimized as early as the planning phase in order to keep heat distortion as low as possible and seam quality consistently high.
-
Modular construction methods
With the introduction of our LINEARWELD modular systems we have been offering customizable longitudinal seam welding machines since 2016, which can be converted to new components at lightning speed thanks to variable clamping widths, tube diameters and adjustment options. Our CORNER ONE Corner seam and ROTAWELD Circular seam welding machines: Standardized basic units are combined with specific clamping and guide modules to precisely weld even complex geometries.

The company begins manufacturing and selling industrial equipment in steel and metal construction. An important product is transport racks for the automotive industry.
1987
Expansion of the product range to include simple welding automation solutions. Purchase of the company by Klaus Schülein after the unexpected death of Georg Fohrer.
1989
The first LNA longitudinal seam welding machine is built and is a widely sold product on the German market in the years following reunification.
The first special solutions for the automation of welding tasks are realized.
1992
The company's first trade fair appearance at the Euroblech 92 in Hanover.
The enhanced longitudinal seam welding machine, now equipped with a programmable logic controller (PLC), is given the brand name ELENA® and is presented in the new standard color RAL 4006.
1994
Change of name to Schnelldorfer Maschinenbau GmbH. At the same time, the company focuses on the high-quality automation of complex welding tasks. Dr. Wolf joins the company as Managing Director.
1998
The CORNERWELD clamping and machine concept for welding corners is developed. In the following years, standardization takes place through the implementation of many customer projects.
2000
Design and construction of an automatic welding line for the production of airbag cold gas generators with four interlinked welding stations.
2002
Inauguration of a new assembly hall and a further office building with space for the expanded construction departments and reception area.
2006
Use of the first welding robots at Schnelldorfer Maschinenbau to solve special welding tasks. Development of a complex fixture system for welding stainless steel containers in the white goods sector.
2008
The machine type ELENA® VI for automatic clamping and longitudinal seam welding of pipes is developed. Patent protection is applied for the new clamping concept.
2010
Increasingly complex clamping devices with their own PLC control for robot welding with arc and laser processes are designed, built and integrated into the production processes in partnership with the customer.
2011
Schnelldorfer Maschinenbau GmbH achieves a new record turnover in the course of the good economic situation. The continuously developed ELENA® longitudinal seam welding machine continues to make a fundamental contribution to the company's success. After 17 years as Managing Director, Dr. Wolf retires. Dr. Daus takes over the management of the company.
2012
