Strike an arc on aluminum for the first time, and you'll immediately understand that this is not steel: no color warning, no forgiveness, no margin for error. One second, you're staring at a silver surface. Next, there's a hole where your workpiece used to be. If you've tried welding aluminum and failed or avoided it entirely,How to Weld Aluminumwas written for you.
Most welders hit a wall with aluminum because nobody explains why it behaves differently or gives them the exact settings to use. The oxide layer that fights fusion. The heat that disappears three times faster than steel. The crack-sensitive alloys that split before they cool. How to Weld Aluminum closes every gap with real machine settings by material thickness, filler rod selection matched to your base alloy, and AC balance values you can dial in before your first bead.
Inside this guide, you'll get:
Complete TIG and MIG settings tables, amperage, AC balance, frequency, wire feed speed, and gas flow by thickness
A clear filler rod selection system covering 4043, 5356, 4047, 4943, 5183, and 5556
Alloy identification and weldability charts for all 7 aluminum families
Dedicated chapters on equipment setup, oxide removal, heat management, and distortion control
12 hands-on projects from practice coupons to hull patches, tube frames, cast repairs, and shop fabrication
A complete troubleshooting reference for porosity, hot cracking, burn-through, and MIG feeding problems
Marine, automotive, and repair welding chapters covering real-world scenarios
Stop sending aluminum work to someone else. How to Weld Aluminum gives you the process, the settings, and the confidence to do it yourself from your first test bead to your first paying repair. Add it to your cart today and weld aluminum this week.
