Description

Technical Field

[0001] The utility model relates to the field of welding, in particular to a plastic parts welding elbow welding gun. Background Art

[0002] Welding is a manufacturing process that uses heat, pressure, or both, with or without filler materials, to achieve atomic bonding between two or more separate workpieces (usually metals or thermoplastics), creating a permanent connection. Thermoplastic welding primarily relies on the principle of thermal fusion. Plastics are composed of high molecular weight polymers. When heated to a certain temperature (the melting point of the plastic), they transition from a solid state to a viscous, fluid state. At this point, the molten portions of two plastic parts are brought into contact and pressure is applied, causing the molecular chains to diffuse and entangle. Upon cooling, the plastic returns to a solid state, and the interaction of the molecular chains connects the two parts. For example, during the welding of a plastic elbow using a welding torch, hot air melts the plastic on the elbow and pipe surface. The plastic is then brought into contact and cooled, completing the weld.

[0003] A welding gun is required for welding plastic parts. However, the welding head of the current welding gun is inconvenient to disassemble, which makes it time-consuming and laborious for workers to replace the welding head. In addition, since the current welding gun lacks a protective structure for the welding head, the welding head is easily damaged by external factors when idle, thereby reducing its service life.
