The level of automation and intelligence in welding production is mainly reflected in the development level of welding robot technology. Currently, most of the widely used welding robots belong to the teaching and playback type. This type of robot does not have the ability to handle environmental changes such as workpiece assembly errors and thermal deformation during welding.


    As well as the ability to adapt to changes in the working object, developing a new generation of intelligent robots with multiple sensing functions that can automatically formulate motion trajectories, welding torque poses, and welding parameters will become the main development direction.

Development achievements of modern welding technology: 1. In terms of equipment production and research, laser welding mainly produces kilowatt level CO2 laser equipment and solid YAG laser equipment below 1 kilowatt. The research on laser welding in China mainly focuses on the formation mechanism, characteristic analysis, detection, control, simulation of deep penetration laser welding, application of laser arc composite heat source, laser surfacing, and so on.

The university analyzed the acoustic signals of the penetration state from the perspectives of sound and electricity, and proposed an equivalent circuit and mathematical model of electrical characteristics for laser welding plasma; In terms of suppressing the negative effects of plasma, Xiao Rongshi and Zuo Tiechuan from the National Institute of Industry, University, and Research Laser Technology Center proposed the method of blowing dissimilar gases through double-layer inner and outer circular tubes; Liu Jinhe from Northwestern Polytechnical University proposed the external magnetic field method.
