How To Weld Vinyl Sheets Together

Fit a tack welding nozzle on your welding gun then apply a little bit of heat.

How to weld vinyl sheets together.

In addition the two sheets being welded together are farther apart so the installer is filling a gap with weld rod instead of welding the edges of the two pieces together. Then immediately apply pressure to fuse them together allow to cool down if too hot. Start at a corner and slowly pull the vinyl up at an angle making sure all the parts of your design remain attached to the carrier sheet. Before you start the actual weld pin loose pieces of plastic together by melting the ends of the joint.

Roll the edges of both sheets away from the seam. If you notice part of your design lifting up you can just hold it down with your finger while you pull off the vinyl surrounding it. The heat in the extruded bead is sufficient to cause it to weld to the adjacent surfaces. Notice the groove in photo 5 below has a more pronounced groove on one side of this failed heat weld.

Spread vinyl floor adhesive on the floor with a 1 16 by 3 32 inch notched trowel. A bead of the same materials is extruded between two sections and then the two sections are immediately pressed together. This will keep the plastic from moving as you complete the weld. Rapid angular oscillations are applied to heat the plastic parts to be joined.

Apply a uniform bead 1 8 to 1 4 wide centered at the seam. Then apply heat again. Wait for the plastic to begin melting joining the pieces of plastic together. Using the low setting on my heat gun gently heat up the two sheets till they get tacky.
