HDPE welding is a form of plastic welding commonly used in plumbing and underground piping to join lengths of pipe together. A quick and simple process, HDPE welding simply involves heating HDPE to the correct temperature and then fusing it together with another piece. It requires no weld filler rod or extra safety measures, and is one of the most popular methods of joining HDPE plastic together.
But what is HDPE? An acronym of high density polyethylene, HDPE is a thermoplastic made from petroleum. It's one of the most popular forms of plastic in used and is known for its strength-to-density ratio and its resistance to many different solvents.
Aside from plumbing, HDPE welding is also commonly used in signs, billboards, and banners, where it helps created lightweight, flexible, cost-effective, impact and wear resistant, and chemical and moisture resistant products.
HDPE welding can take place one of any number of ways:
- Extrusion welding: This type of welding allows the application of bigger welds in a single weld pass. It is the preferred technique for joining material over 6 mm thick. Welding rod is drawn into a miniature hand held plastic extruder, plasticized, and forced out of the extruder against the parts being joined, which are softened with a jet of hot air to allow bonding to take place.
- Hot gas welding: Also known as hot air welding, this is a plastic welding technique, which is analogous to metals, though the specific techniques are different. A specially designed heat gun, called a hot air welder, produces a jet of hot air that softens both the parts to be joined and a plastic filler rod, all of which must be of the same or a very similar plastic. Hot air/gas welding is a common fabrication technique for manufacturing smaller items such as chemical tanks, water tanks, heat exchange and plumbing fitting. Two sheets of plastic are heated via a hot gas or a heating element and then rolled together. This is a quick welding process and can be performed continuously.
- Speed welding: With this process, the plastic welder, similar to a soldering iron in appearance and wattage, is fitted with a feed tube for the plastic weld rod. The speed tip heats the rod and the substrate, while at the same time it presses the molten weld rod into position. A bead of softened plastic is laid into the joint, and the parts and weld rod fuse. With some types of plastic such as polypropylene, the melted welding rod must be “mixed” with the semi-melted base material being fabricated or repaired. These welding techniques have been perfected over time and have been utilized for over 50 years by professional plastic fabricators and repairers internationally. Speed tip welding method is a much faster welding technique and with practice can be used in tight corners. A version of the speed tip “gun” is essentially a soldering iron with a broad, flat tip that can be used to melt the weld joint and filler material to create a bond.
- Electrofusion: This method of joining HDPE and other plastic pipes uses special fittings that have built-in resistive wire which is used to weld the joint together. The pipes to be joined are trimmed, cleaned, inserted into the electrofusion fitting (with a temporary clamp if required) and a voltage (typically 40V) is applied using a device called an electrofusion processor. The processor controls how much voltage is applied, and for how long, depending on the fitting in use. As current is applied to the resistive wire, the coils heat up and melt the inside of the fitting and the outside of the pipe wall which weld together producing a very strong homogeneous joint. The assembly is then left to cool for a specified time. The joints produced tend to be more reliable than threaded fittings sealed with O-rings.
