Before you call

Aluminum welding: the short version

TIG or MIG welding on aluminum: boats, trailers, railings and parts.

When you need it

  • Cracked boat hulls and pontoons
  • Aluminum trailers and truck parts
  • Railings, ramps and docks
  • Custom aluminum frames and brackets

What to send the shop

  • Photos of the crack or break, close up
  • The alloy, if you know it
  • What the part does and what it carries
  • Whether it comes off, or needs mobile work

Typical lead time

Ask about timing after the shop reviews the damage, alloy and access to the part.

Ask the shop

3 questions worth asking

  1. Q1

    Do you TIG weld aluminum, or use a spool gun?

  2. Q2

    Can you weld my alloy and work on a casting?

  3. Q3

    Is your company certified to CSA W47.2 for aluminum?

Questions

Aluminum welding FAQ

What should I tell an aluminum welder?

Send clear photos of the damage and the whole part. State the alloy if known, what the part carries and whether it can be removed.

Which certification covers aluminum welding?

CSA W47.2 is the CWB company certification standard for fusion welding of aluminum. Ask which certification applies to your work.

Can I ask for mobile aluminum welding?

Say where the part is and whether it can be removed. Ask the shop to confirm that it can weld your alloy on site.

Good to know

  • Say whether the part is cast or made from sheet or plate, if you know.
  • No South Shore shop we checked posts prices for this. Send a request to compare quotes.
