Contract work allows you to outsource work if your company doesn’t have enough capacity or if you don’t have the necessary machinery. You will supply the materials and components to be processed and we will produce the required product for you.
Gas metal arc welding (GMAW) is an arc welding procedure during which a consumable welding rod is continuously fed with the aid of a variable speed motor. The diameter of the welding rod is usually between 0.8 and 1.2 mm (on occasion also 1.6 mm). The inert gas or mixed gas is fed to the welded joint via a nozzle at the same time as the rod, at approx. 10 l/min. The gas protects the liquid metal under the arc against oxidation in order to prevent a weakening of the welded joint. MAG welding (metal active gas welding) uses pure CO2 or a mixed gas consisting of argon and small amounts of O2 and CO2 (amongst other “corgon”). Depending on the composition, it is possible to influence the welding process (penetration, droplet size, spraying loss). MIG welding (metal inert gas welding) usually uses argon as an inert gas. The expensive inert gas helium is also used on occasion. The MAG procedure is mainly used for steel, the MIG procedure is commonly used for non-ferrous metals.
For gas metal arc welding, it is also possible to use cored wire which can contain a slag builder or alloy additives. Core wire serves the same purpose as the coatings of the pencil electrode. On the one hand, the contents add to the welding volume. On the other hand, they form a slag on the weld bead and protect the joint against oxidation. The latter is especially important when welding high-grade steels because oxidation has to be prevented even after the burner and the protective gas shield are moved forward.
We process workpieces up to a cube size of 2000 x 2000 x 1400 mm for you.
We process workpieces with a diameter of up to 630 mm and a length of 2000 mm.
We are certified for magnetic particle testing according to DIN EN ISO 9712 MT/PT Level 2.
We will clean your components thoroughly and reliably. With this procedure, it is also possible to remove corrosion or old paint layers.
Your sheet metal will be bent into the required shape. We use a Trumpf sheet metal bender Truma 85S.
