There are various types of geomembrane welding equipment. From large to small, they are extrusion welding machines, climbing welding machines, and hot air guns. The so-called extrusion welding machine heats plastic welding rods, then uniformly welds the melted plastic at the joints, thereby achieving the purpose of welding. The operation of the extrusion welding machine requires two people. During operation, one person is responsible for retracting and releasing the welding rod, and one person is responsible for operating the equipment.
The operation of the climbing welding machine is relatively simple. It mainly welds the membranes together through upper and lower layer welding. Using a climbing welding machine requires a certain understanding of the temperature and speed of the equipment, knowing what temperature and speed to use for what thickness of membrane material. Also, the cutting of membrane materials during welding operations, etc.
The main function of the hot air gun is actually similar to the hair dryer we use, except that its temperature is higher, reaching over 400 degrees. The use of hot air guns is mostly in places where geomembrane needs to be repaired, that is, the so-called repairing gaps that cannot be welded by climbing welding machines. For irregular construction sites, its use is relatively large.
