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 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...
متن کاملNeural Network-Based Resistance Spot Welding Control and Quality Prediction
This paper describes the development and evaluation of neural network-based systems for industrial welding process control and weld quality assessment. The developed systems utilize recurrent neural networks for process control and both recurrent networks and static networks for quality prediction. The first section describes a system capable of both welding process control and real-time weld q...
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 کاملCurrent Measurement of Resistance Spot Welding Using DSP
This study aims to calculate the resistance spot welding current digitally at a fast speed. The conventional open-loop spot welding machine cannot measure the current, thus the welding quality varies. The welding time of spot welder is very short, but the welding current is strong and it is hard to be measured, thereby resulting in the uncontrollability of welding quality. This study uses a hig...
