Aluminium TiG welding
TiG welding aluminium sheet metal fabrications
Here we have an aluminium housing for a light fitting with folded sides that needed to be joined to stop the sides being pulled out when is use. The simplest solution was a small aluminium TiG weld in each corner on the inside to lock the corners together. The weld didn’t need to be cleaned up again as the final finished housing was powder coated black and once the cover was screwed on the inside wasn’t seen again. This 3mm thick aluminium sheet metal fabrication, manufactured in our factory in Fareham, Hampshire was produced in a batch of 200 units along with the housing covers. TiG welding is so versatile when it comes to thin sheet metal fabrications and we often use it for fabricating components and assemblies in aluminium, mild steel and stainless steel. If the gauge is a lot thicker or the weld needs to be larger then aluminium MiG welding is a possible solution.
Aluminium MiG welding
MiG welding aluminium sheet metal fabrications
Here we have some sheet metal aluminium trays that have been manufactured from 3mm thick 5251 aluminium alloy in September 2015 with continuous MiG welding along the corner seams. The advantage of MiG welding over TiG welding was the speed that these MiG welds could be carried out and the reduction in heat and distortion. The trays only needed a light sanding off and then they were ready for powder coating.
Aluminium TiG welding assembly
TiG welding aluminium sheet metal assemblies
TiG welding can be used for more than just fusing together joints, it can also be used to assemble a series of parts together to create one sheet metal fabrication. Here we have a rolled aluminium ring with a TiG welded joint, flat aluminium plate and folded box section fabricated from 2 L shaped pieces. The final product was a small housing to go behind a ceiling panel, plastered in place to hold a fibre optic light fitting. The small TiG welds did not need to be cleaned off as they were so small and out of sight in the final installation.
