Plastic material failures such as fractures or cracks can be repaired by joining. In the industrial world, the joining of two or more plastic parts can be done with plastic welding technology, one of the methods of plastic welding is hot-gas welding (HGW). HGW is a welding process for plastic materials, but it is known that plastic materials have poor heat conductivity. The research objective was to determine the role of the foundation plate temperature on the tensile strength and the impact on HDPE sheet welding using hot gas welding. The method uses the hot gun setting and the base plate temperature during the welding process (30°C, 60°C, 90°C and 120°C), as well as the hot air flow temperature of the hot gun (250°C, 300°C, and 350°C). To obtain data, it was carried out by tensile and hit tests using standard specimens, respectively ASTM D 638-03 and ASTM D 6110. The results of research, it was found that the temperature of the foundation plate and the temperature of hot gun hot air flow during the hot gas welding process had an effect on the tensile strength and the hit of the HDPE welding joint. Optimization of tensile strength and time of 18.78 MPa and 0.018567 Joule/mm2 respectively, these values are obtained from the combination of an anvil plate temperature of 120°C and hot hot air flow of 200°C.
