How to weld acrylic sheets.

To glue acrylic with solvent glue typically a squeeze bottle applicator with a needle tip is used. To weld two sheets of plexiglass we need to use plexiglass solvent. Lightly squeeze the applicator while pulling it toward you. Move the tip of the welding gun slowly over the plastic for a speed weld.

Put the acrylic on the edge where you want it and place the needle of the glue filled applicator where the two pieces meet. To glue two pieces of acrylic together you must secure both sheets with a clamp or have an assistant hold them together so that they fit perfectly while you apply the solvent. Seldom is welding used to join polycarbonates because the degree of success has never been constant. Use clamps or masking tape to hold acrylic sheeting in place while applying solvent.

If acrylic sheeting is being welded for box corner joints apply solvent on the inside edge of the acrylic sheeting. The cement will begin to dissolve the acrylic and form a strong bond immediately. Hold the gun downward at about a 45 degree angle touching the edge of the nozzle to the plastic. Apply the desired amount of acrylic fluid medium inside the tape using a one half to two inch soft artist brush.

Use a needle nose application bottle to apply the acrylic cement to the acrylic sheets.

Capillary action will draw the glue into the joint. Use masking tape on the glass to tape out the desired size and shape of the acrylic sheet. Then heat the plastic until you see it beginning to melt. However since this method is used this blog mentions it too.
