The pulsed MIG is the best for professional boast 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.
