Applications & markets
Dumaco is able to supply customers with big and small welding constructions. Our certifications mean that customers can rely on us to deliver the highest quality result. Welding applications include crane booms for trucks, frames, doors and tanks.
Welding can be used in virtually every market. Depending on what a customer needs, we are able to supply both semi-finished and finished products. Several of the important markets we serve with our welding work follow below:
About (robotic) welding
Dumaco has a high level of expertise and a whole range of (robotic) welding options. We’re not exaggerating when we say that welding is our specialty. We offer various welding processes, including MIG, MAG, TIG, robotic, stud and spot welding. The welding lines in our workshop include both manual and robotic welding equipment.
What does (robotic) welding involve?
Welding is a process in which pressure and heat are used to join two materials. The heat of the welding equipment is used to liquefy the sheet metal at the weld point. Once the weld point has been liquefied, new material can be added and the combination of the two creates a strong whole.
Each different type of material, thickness and application requires a different welding method. Dumaco uses a number of welding methods: MIG, TIG, MAG, robotic, spot and stud welding. The appropriate welding method is chosen in the drawing/design phase. Dumaco’s welding expertise means that it is always able to advise you and help you choose the right welding process for you. The goal will always be to offer you the best price and quality possible.
MIG and MAG welding
MIG and MAG welding is two of the welding methods used most at Dumaco. We mainly use them for thicker sheets of steel and have both automated and manual options. One advantage of MIG and MAG welding is the possibility of a high production speed and complex welding positions. Also, no post-processing is necessary because of the absence of any deformation.
Robotic welding is a fully-automated process in which the welding torch is controlled by a robot. This has a number of advantages over manual welding. Firstly, the welding quality is higher and consistently meets the same tolerances. Secondly, production time is reduced; this lowers costs. One disadvantage is the sheet-metal size limitation. Our welding robots can process sheet metal measuring a maximum of 6 meters.
TIG welding is mainly used for thinner thicknesses of (stainless) steel and aluminum sheet-metal. TIG welding paves the way for a high and consistent welding quality. TIG welding can be done robotically or manually. This makes the process manageable. TIG welding is a complex process that can only be carried out by a highly-skilled welder.
Stud welding (also called butt welding) involves the ignition of an arc between one end of the stud and the workpiece.
Spot welding involves the application of pressure and heat to bond metal surfaces together. The tips on the machine – which is where the electrodes are located – are quite small. Because of this, the current generated is concentrated on a small area.
