Aluminium welding
Aluminium is a material with many advantages – low weight, good corrosion resistance and high formability – but it also places special demands on welding. At Ollerup Maskinfabrik, we have solid experience in welding aluminium and know how to handle the sensitive material so that the result is strong, durable and visually appealing.
Aluminium requires specialist knowledge
Aluminium conducts heat much better than steel and has a lower melting point. Therefore, welding aluminium requires great precision and the right equipment. We mainly use TIG and MIG welding depending on the nature of the task, and our welders are experienced in avoiding common defects such as porosity, cracks, and deformation.
We weld for all industries
Our aluminium welding is used in everything from machine parts and transport equipment to prototypes and industrial constructions. We offer both single-piece and series production – and always deliver with a focus on functionality, durability, and a fine finish.
Modern equipment and high precision
We have invested in modern welding equipment that is adapted for working with aluminium – regardless of the material's thickness. Our workshop handles both small and large items, and we offer measurement, fitting, and finishing as part of the solution.
MIG and MAG welding
MIG/MAG welding is an extremely flexible welding method that can be used for aluminium, steel and stainless steel. During the MIG/MAG welding process, we add wire, which is melted onto the material.
The difference between MIG welding and MAG welding is the use of gas. When using MIG (Metal Inert Gas), the gas is inert, which protects against the atmosphere. When using MAG (Metal Active Gas), the gas is active. The gas functions as an active part of the chemical process.
TIG welding
When using TIG welding (Tungsten Inert Gas), we use an inert gas that prevents other gases from accessing the welding material.
We often use TIG for pipe and pipeline welding. Tungsten has an extremely high melting point and is therefore often used for more precise and accurate welding on thin material.Â
MMA welding
MMA welding, Manual Metal Arc, is also called electrode welding. MMA welding is a welding method where an electrode (electronic rod) is mounted on an electrode holder and forms an arc between the electronic rod and the material.Â
MMA welding can be used for outdoor welding or for welding pipes, among other things.Â
Laser welding
As something relatively new, we offer LASER WELDING of various workpieces in both stainless and black steel. Â
In laser welding, we join metals using a concentrated laser beam with a power of up to 3 kW. When welding stainless or black steel plates in thinner material thicknesses, joining can be carried out at a very high welding speed, measured in metres per minute. In laser welding, the heat input is concentrated on a very small area of the workpieces, which reduces the risk of distortion, twisting and geometric impact on the workpieces, as well as reducing the total heat input to an absolute minimum!
Compared to other welding processes we offer, it provides laser welding the following advantages:
- High welding speed
- Significantly reduced heat impact and low heat input – Ideal for aluminium
- Narrow precisely placed weld seams
- Trouble-free welding of thinner materials such as foils and relatively thin sheets
- Welding of foil/thin sheets to thicker materials and material thicknesses can be carried out without problems
Certificate welding
At Ollerup, we have certified welding, and this is within TIG, MAG, and Electrode. Our welding certifications are in the following areas:
- TIG 141, 142
- MAG 135, 136, 138
- Electrode 111
