Problems solved by technology

2: The thermal expansion coefficient of aluminum material is 50% larger than that of steel material, so the welding pressure has a greater impact on aluminum material, and the adaptive technology of steel welding does not monitor the welding pressure, so the welding quality cannot be guaranteed

Abstract

The invention discloses a self-adaptive welding system based on an aluminum material, and relates to the technical field of welding. The self-adaptive welding system comprises a welding control cabinet which is connected with welding tongs, the welding tongs are connected with a transformer, a pressure sensor and an electric cylinder, the transformer is connected with a current sensor and a voltage sensor, and a PC is connected with the welding control cabinet; the welding control cabinet comprises a pressure signal collector, an electric leakage detector and a power source; and the pressure signal collector, the electric leakage detector and the power source are all connected with a welding controller, the welding controller is connected with the welding tongs, and the welding controlleris connected with the welding tongs and the PC. The invention further discloses a self-adaptive welding method based on the aluminum material. A workpiece is welded through preheating treatment and main welding by collecting sample curves, and automatic adjustment is conducted according to feedback values when welding generates disturbance. The self-adaptive welding system and method have the advantages that the production cost is reduced, the productbility of the workpiece is improved, the welding quality is improved, and the process safety is improved.

Description

technical field [0001] The invention relates to the field of welding technology, and more specifically relates to an adaptive welding system and method based on aluminum materials. Background technique [0002] In order to meet the requirements of emission regulations and cater to consumer preferences, new materials such as metal aluminum, metal magnesium, carbon fiber, and advanced high-strength steel are widely used in automobile manufacturing. At present, self-adaptive technology has been proved to be an effective means to overcome disturbance factors and control the quality of solder joints in the field of steel resistance welding, but self-adaptive technology for steel is not suitable for aluminum welding. [0003] The adaptive technology of steel resistance welding cannot adapt to the characteristics of aluminum welding, and analyze the characteristics of aluminum and steel: 1: Aluminum has lower material resistance than steel, that is, higher conductivity, so shunt we...
