Current paper presents review of Interrelationships between Welding Parameters of Hot-Gas Welding. Today, joining of thermoplastic composite structures is gaining more importance since thermoplastic composite materials are increasingly being used to replace metallic and thermoset composite to better withstand static and fatigue loads in aerospace, automotive, and marine industries.Plastic welding is described in ISO 472 as a process of uniting softened surfaces of materials, generally with the help of heat (except solvent welding). Hot gas welding is one of the external heating methods. In case of hot-gas welding the parameters of welding such as welding temperature, flow rate, welding speed, welding force,gas,angle,filler rod, Pressure of hot air/gas, Gap distance and shoe influence the strength of the welded joint.This article has studied various literature presenting properties of various polymers, different techniques for plastic welding, comparative study of different techniques, effect of various process parameters on strength and quality of welded joint.
