Aluminum Welding in Detroit: what to expect
Aluminum welding in Detroit covers boats and pontoons, docks and ladders, trailers, truck and trailer parts, ramps, and fabricated aluminum parts. With the Detroit River, Lake St. Clair and inland lakes in Oakland and Livingston counties, aluminum boat and dock repair is common across Metro Detroit.
Aluminum is harder to weld well than steel. It conducts heat fast, forms an oxide layer that must be cleaned off, and many alloys lose strength near the weld. Welders typically use TIG for thin and precise work and pulsed or spool gun MIG for thicker parts, with pure argon shielding gas and the right filler alloy. Cast aluminum parts and some alloys cannot be welded reliably, so a good welder will say so.
For stainless parts, see stainless steel welding. For aluminum trailers, see trailer repair welding. Compare aluminum welders in Metro Detroit.
What a proper job includes
- Identification of the aluminum alloy or part type
- Cleaning and oxide removal before welding
- TIG or MIG process chosen for the thickness
- Filler alloy matched to the base metal and use
- Crack repair with drilled crack stops where needed
- Leak testing on boats or tanks when appropriate
- Finish work: brushing, grinding or polishing
What drives the price
- Alloy and whether it is cast or wrought
- Thickness and how clean the metal is
- Location: shop, dock or on site
- Leak testing for hulls and tanks
- Cosmetic finish requirements
- New parts that must be fabricated

Codes, permits and certifications
Most aluminum repairs do not need a permit. Structural aluminum on buildings follows its own welding code (AWS D1.2 for aluminum structures), and commercial work may require engineered details and inspection. Docks and seawalls on regulated waters may need state permits for new construction, so confirm with the relevant agency before building new structures.
Welders are usually qualified by passing a test to a specific code and process, such as AWS D1.1 for structural steel, rather than holding a general state trade license. Ask for current welder qualification records for the process and position on your job, and proof of liability insurance.
