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 modern welding equipment suited to working with aluminium – from thin sheet to heavy parts. We can cut aluminium up to 100 mm on our plasma cutter, form the parts on our press brakes and check the finished parts on our Zeiss 3D coordinate measuring machine.
TIG welding of aluminium
TIG welding gives full control of the heat input and is used for thin sheet, visible joints and parts where the finish matters. Aluminium conducts heat away quickly and has a thin oxide layer that has to be broken – so TIG welding aluminium requires both the right settings and an experienced welder.
MIG welding of aluminium
For thicker sections and longer weld seams we use MIG welding, where the wire is fed automatically. This gives a higher welding speed and suits structures, frames and series parts in aluminium.
Robotic welding of aluminium
For series we weld aluminium in our robotic welding cell. The robot handles parts up to Ø2200 mm and 4000 mm in length and delivers the same weld quality from the first part to the last – an advantage with aluminium, where a consistent heat input is crucial.
Quality and documentation
Our welding production is certified to EN ISO 3834-2, which sets comprehensive quality requirements for welding both steel and aluminium. The welding is planned and overseen by our own certified welding coordinator (IWT), and we supply, as required:
- Welding procedure specifications (WPS) and weld logs
- Material certificates and traceability
- NDT reports from an accredited third party
- Measurement report from Zeiss 3D coordinate measurement
From plate to finished aluminium component
We can deliver the whole process from plate to finished welded aluminium component in one place:
- Plasma cutting of aluminium up to 100 mm
- Press brake bending with up to 500 tonnes and 4500 mm bending length
- Rolling of plates and profiles
- Sawing of profiles and tubes
- Deburring of edges
Questions about welding aluminium
Which welding methods do you use for aluminium?
We weld aluminium with TIG and MIG. We use TIG for thin sheet and visible joints, MIG for thicker sections and longer seams. For series we use robotic welding.
How do you avoid porosity and distortion in aluminium?
Aluminium requires clean, well-fitted joint preparation, the right filler material and control of the heat input. Our welders are experienced in avoiding the typical defects such as porosity, cracks and distortion.
Is aluminium welding covered by your quality system?
Yes. Our EN ISO 3834-2 certification covers welding of both steel and aluminium, and the welding is overseen by our certified welding coordinator (IWT).
Can you weld aluminium in series?
Yes. We weld both one-offs and series, and for larger series we use our robotic welding cell, which handles parts up to Ø2200 mm and 4000 mm in length.
Can you also cut and form the aluminium parts?
Yes. We plasma cut aluminium up to 100 mm, press brake bend with up to 500 tonnes and roll plates and profiles. That way the whole part can be made in one place.
