Can Acrylic be Welded?

Yes, acrylic can be welded. It can be welded to itself using clear PVC welding rod. You can use the same techniques used for welding PVC to weld acrylic. Welding temperature for acrylic is 400-450 degrees F. The rod is usually held at a 90 degree angle to the seam and you should use 2-3 PSI of pressure.
Care should be taken to avoid charring of the materials. Acrylic also has a tendency to stress crack and will often froth and blow during welding. Finished lines will often show air inclusions.
