Aluminum Welding Services

Boat parts, trailers, ladders, truck bodies and custom aluminum work welded with the clean, controlled technique this metal demands.

Aluminum is light, strong and corrosion resistant, which is why it appears on boats, trailers, truck bodies, ladders and equipment. It is also unforgiving to weld: it conducts heat quickly, forms a tough oxide skin and can crack or burn through when treated like steel.

We weld aluminum with the process, filler alloy and shielding gas the base metal calls for, cleaning thoroughly before each weld. Cracked boat transoms, trailer frames, truck toolboxes, fuel and water tanks (once safely prepared), brackets and custom aluminum fabrication are all within reach.

Cleanliness is everything

Aluminum oxide melts at a much higher temperature than the metal beneath it, and oils cause porosity. We remove oxide and contaminants right before welding.

Heat and distortion

Aluminum spreads heat fast and distorts easily. We manage heat input, clamp carefully and sequence welds to keep parts flat.

Know the alloy

Not all aluminum welds equally. Some alloys crack easily, and cast aluminum needs special handling. We identify the alloy and tell you honestly what is possible.

Preventing galvanic trouble

Aluminum in contact with steel or copper in a wet setting can corrode quickly. We use isolating washers, coatings or other details to prevent the metals from attacking each other.

What is included

  • Identification of the alloy and damage
  • Cleaning to remove oxide and contaminants
  • Welding with matched filler and gas
  • Straightening and finish work
  • Leak or fit check where relevant
  • Notes on care of the repair

How it works

Our process, start to finish.

  1. 01

    Call or send photos

    Tell us what is broken or what you want built and send photos if you can. We plan the visit so the truck arrives ready.

  2. 02

    Look and quote

    We see the work, ask about the metal and access and give you a clear written price.

  3. 03

    Schedule

    We agree a day and an arrival window, and call when we are on the way.

  4. 04

    Safe setup and welding

    Work zone cleared, fire watch in place, then careful welding in the right process for the metal.

  5. 05

    Finish and clean-up

    Welds ground, primed and painted, and the area left clean.

  6. 06

    Walk-through and follow-up

    We walk through the finished work with you and note anything to watch.

Questions

Aluminum Welding FAQ

Can you weld cracked aluminum boat parts?

Often. We assess the alloy and the damage, and weld with a process and filler suited to marine aluminum. Corroded or thin hulls need careful evaluation.

Why is aluminum harder to weld than steel?

It conducts heat quickly, forms a stubborn oxide skin and can burn through. It needs cleanliness, the right equipment and practice.

Can cast aluminum be welded?

Sometimes. It depends on the alloy and condition. Cast parts are often brittle or oily, so we test and advise before welding.

Can you repair aluminum tanks?

Only after they are properly cleaned and made safe. We discuss the safety steps before touching any container that held fuel or chemicals.

Why does aluminum corrode next to steel?

Dissimilar metals in water form a galvanic cell, and the aluminum suffers. Isolation, coatings or different fasteners prevent it.
