Abstract: In this era, the world temperature is rising. Manufacturers in the air conditioning industry are developing environmentally friendly compressors and refrigerants. However, the current refrigerant, R32, has a very high pressure, which negatively affects the copper pipes of the air conditioner, making them prone to leaks. To save costs, a brazing method is often used to connect the pipes, but this method often causes repeated leaks in the welded area. This study was conducted experimentally by testing the welded pipes, applying pressure, and examining the microhardness. The purpose of this study is to analyze the microhardness of the welding results of copper material on 0.41mm, 0.58mm, 0.61mm AC pipes. The results of reading this journal provide insight into the welding results of copper pipes in air conditioning systems by pressure test and hardness test.
