Design of Spot Welding Robot
Welding robot has played an extremely important role in the welding production of high-quality, high-efficiency. The paper designed the hardware structure and software of spot welding robot. The hardware design mainly includes the major modules of arm and base; the hardware design includes two parts: manual mode and automatic mode. Manual mode is generally used for the robot system installation...
متن کاملFinite element simulation of laser spot welding
The present work reports on a two-dimensional axisymmetric nite element analysis of heat ow during laser spot welding, taking into account the temperature dependence of the physical properties and latent heat of transformations. An analysis based on conduction heat transfer alone, but using the ‘double ellipsoidal’ representation of the laser beam, seems to be suf cient to estimate the tra...
متن کاملResistance Spot Welding: A Heat Transfer Study
A heat transfer study of resistance spot welding has been conducted both theoretically and experimentally. A numerical solution based on a finite difference formulation of the heat equation has been developed to predict temperature distributions as a function of both time and position during the welding process. The computer model also predicts the temperature distribution through the copper el...
متن کاملResistance Spot Welding of Steels: Modeling and Simulation
Resistance spot welding (RSW) includes many variables that can influence the weld properties. The purpose of this study is to develop an analytical model for prediction of thermal history and weld microstructure in RSW and to find the most important process parameters that influence the weld microstructure. A one dimensional model is proposed for prediction about thermal history during cooling ...
متن کاملImproving productivity and quality in automotive spot welding
China recently surpassed Japan as the world's second largest automobile market after the United States. Annual output of automobiles is close to six million units a year. A key tool in automotive production is the spot welding gun and the industrial robot. One of the most important parameters of a spot welding gun is force tolerance. ABB is helping the Chinese automotive industry improve weldin...
