How to Weld Aluminum Boats? Step by Step Guide

There are several essential steps that you should follow when welding boats. Follow this step by step guide below.

How to Weld Aluminum Boats? Step by Step Guide

Step 1: Begin by gathering enough of the right grade aluminum. The most common kinds for this task are the 5086 or 5083. Purchase your design files, then contract someone to cut the design for you.

Step 2: When it is time for welding, avoid the TIG welding if you want to keep it clean. Instead, use a spool-gun, or better still, you can use the pulse MIG machine. The pulsed MIG is the best for professional boat building, and it does an excellent job at it. Spool guns are also suitable for building boats with aluminum and are more affordable.

Step 3: Set up the jig. It is essential that the jig does not move and is completely square.

Step 4: Use incremental back-step welding. The primary idea behind it is to eliminate distortion as much as possible. Beginning from the boat’s center, you work your way in six inches increments, but welding towards the center.

Step 5: Forming the handrails. You will need a lot of experience or a proper bending machine for this part.

Step 6: Transom height. This is where you decide on the right motor to mount on your boat before building the transom.
