How To Weld Acrylic Sheets

However since this method is used this blog mentions it too.

How to weld acrylic sheets.

To weld two sheets of plexiglass we need to use plexiglass solvent. To glue acrylic with solvent glue typically a squeeze bottle applicator with a needle tip is used. Apply cement solvent on both sides of sheeting if you re applying to flat joints. Use a needle nose application bottle to apply the acrylic cement to the acrylic sheets.

Hold the gun downward at about a 45 degree angle touching the edge of the nozzle to the plastic. Capillary action will draw the glue into the joint. Apply the desired amount of acrylic fluid medium inside the tape using a one half to two inch soft artist brush. Lightly squeeze the applicator while pulling it toward you.

Start at the top of the crack or area you wish to join. Any of the two types of welding vibration welding and ultrasonic welding are used and the results depend on the shape and thickness of the sheets to be bonded. The cement will begin to dissolve the acrylic and form a strong bond immediately. Use masking tape on the glass to tape out the desired size and shape of the acrylic sheet.

It is also very economical and useful. If acrylic sheeting is being welded for box corner joints apply solvent on the inside edge of the acrylic sheeting. Then heat the plastic until you see it beginning to melt. Use clamps or masking tape to hold acrylic sheeting in place while applying solvent.

Seldom is welding used to join polycarbonates because the degree of success has never been constant. Allow the coating to fully dry. Put the acrylic on the edge where you want it and place the needle of the glue filled applicator where the two pieces meet. Move the tip of the welding gun slowly over the plastic for a speed weld.
