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 the queue once the welder has seen photos and identified the material.

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, or is it a casting?

  3. Q3

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

Questions

Aluminum welding FAQ

Which certification covers aluminum welding?

CSA W47.2 is the CWB company standard for welding aluminum. Ask which certification and welding process apply to your job.

What should I tell the welder about the alloy?

Send any material marking or specification you have. Say whether the part is cast, sheet or plate, and explain what it carries.

Which photos help with a repair quote?

Show the whole part, then close-ups of the crack and the area around it. Include sizes and say whether it can be removed.

Good to know

  • Ask the welder to assess the damage before deciding whether to repair or replace the part.
  • No Kitchener shop we checked posts prices for this. Send a request to compare quotes.
