Learn how to weld fly lines using a heat gun and clear heat shrink tubing

Fly Line Welding Videos

Whether we're putting loops on a fly line, repairing a damaged line, or making up our own lines, welding is the way to go. It just requires a low power heat gun, a nozzle on the front of it to concentrate the air flow, some clear heat shrink tubing and some sharply pointed scissors.

I'm often questioned by anglers concerned that a welded loop won't be strong. A well made loop is actually stronger than the rest of the line. The only risk comes when we overheat a weld. Even an under heated weld will hold reasonably well.

Airflo fly lines are made out of polyurethane (PU) which welds extremely well. Airflo also make fly lines for other fly fishing companies that don't have their own line making divisions. The lines of other fly line companies are made out of polyvinyl chloride (PVC) and the welding qualities of these lines vary from one company to another. PVC lines need plasticizers to help them remain supply. Some very supply lines have their plasticizers cooked off by the welding heat and become brittle. This is also a problem for old PVC lines that have had their plasticizers leech out over time. For this reason, if possible, I would recommend starting one's first welding project with a Airflo made line.
