Re: Welding Urethane Belts

We use a hot air gun and a small jig made out of C channel (1" ID) and square tubing (1" OD). Put one end of the belt in the C channel (with a 1" wide belt, it should be a snug fit). Overlap the other end of the belt by about an inch. Use the heat gun and heat both pieces of belt. Once hot enough, press the joint with the piece of square tubing. Once you figure out the technique (heat setting, distance from workpiece, time) for softening the belts, you will get a perfect weld every time. You do NOT want the belts to start to bubble.
