Aluminium welded with the process and filler the alloy needs.
Aluminium conducts heat quickly, forms an oxide skin instantly, and some alloys lose strength next to the weld. Welding it well means AC TIG or pulsed MIG, the right filler and clean metal.
We weld castings, wrought alloys, tanks, frames and marine parts in the workshop or on site.
The aluminium work we take on.
Cast aluminium repairs
Gearbox and engine casings, pump housings and brackets. Cleaned, preheated and welded with the filler the casting needs.
Hull & East YorkshireWrought alloy fabrication
Frames, tanks, boxes and brackets in 5083 and 6082.
Hull & East YorkshireTanks and vessels
Fuel, water and hydraulic tanks repaired or made new, pressure tested where they hold fluid.
Hull & East YorkshireBoat and marine
Rails, fittings, floors, A-frames and outboard brackets in marine-grade alloy.
Hull & East YorkshireTrailer and vehicle
Aluminium trailer bodies, ramps, side boards and tailgates.
Hull & East YorkshireOn-site repairs
Cracked frames and fittings welded where they are.
Hull & East YorkshireAlloys and fillers
| 6082-T6 | Loses 30 to 50 percent of its strength in the heat-affected zone. We place welds where that matters least. |
|---|---|
| 5083 | Keeps close to parent strength after welding. The alloy to specify for welded structures. |
| Fillers | 5356 for most 5xxx and 6xxx joints. 4043A where crack sensitivity or casting repair calls for it. |
| Castings | Oil-soaked and porous castings are cleaned and preheated before welding. We tell you if a casting is not worth saving. |
| Processes | AC TIG and pulsed MIG |
| Testing | Visual inspection, dye penetrant on request, pressure test for tanks |
Castings are cleaned and preheated before welding.
Oil and porosity are the usual reasons an aluminium repair fails. We deal with both first.

Aluminium welding questions
Not covered here? Call or WhatsApp and ask.
Can you weld cast aluminium?
Usually. It depends on the alloy, how much oil has soaked in and where the crack runs. Castings are cleaned back to sound metal and preheated. If one is not worth welding, we say so before we start.
MIG or TIG for aluminium?
TIG for thin sections, castings and anything on show. Pulsed MIG for thicker sections and longer runs. We choose for the job.
Can you weld aluminium to steel?
Not by fusion welding. The two metals do not mix. We can bolt, rivet or use a bimetal transition piece where the design allows.
Does welding weaken 6082 aluminium?
Yes, in the heat-affected zone. Good design puts the weld where the load is lowest, or uses 5083 instead.
Can you repair an aluminium fuel or water tank?
Yes. The tank is drained, cleaned and purged before welding, then pressure tested afterwards.
Can you weld aluminium on site?
Yes. We bring our own power, shelter the weld from wind and clean the joint back to bright metal before welding.
