A plastic welding rod, also known as a thermoplastic welding rod, is a rod with circular or triangular cross-section used to bind two pieces of plastic together. They are available in a wide range of colors to match the base material's color. Spooled plastic welding rod is known as "spline".
Material properties of the components being welded, hot gas temperature, size of the weld rod, and technique utilized all influence the weld travel speed. Due to the manual nature of hot gas welding, this process is typically slower than other thermoplastic welding methods. Higher weld travel speed can be obtained using a speed tip.
Ultrasonics welding is one of the most commonly used technique for welding advanced thermoplastic composites. This is due for its ability to maintain high weld strength, hermetic sealing, and high production rates. This welding technique operates at high vibrational frequencies (10–70 kHz) [2] and low amplitude. The direction of vibration is ...
[Thermoplastic welding will normally use weld pressures between 72.5 psi and 290 psi. [3] Welding pressure is a parameter determined by the size and area of the part being welded, larger parts require higher pressures to reach the required amount of part upset. [4]
In fusion welding, the heat-affected zone (HAZ) is the area of base material, either a metal or a thermoplastic, which is not melted but has had its microstructure and properties altered by welding or heat intensive cutting operations. The heat from the welding process and subsequent re-cooling causes this change from the weld interface to the ...
Implant induction welding is a joining method used in plastic manufacturing. The welding process uses an induction coil to excite and heat electromagnetically susceptible material at the joint interface and melt the thermoplastic. The susceptible material can be contained in a gasket placed between the welding surface, or within the actual ...
