Abstract: Aiming at the problems of low efficiency, poor quality, high labor intensity and low safety factor in the welding of steel bar and steel strip in China, this paper studies the technology of straightening, feeding welding and blanking intelligent welding of steel bar. The quality uniformity of resistance pressure welding is "two times straightening + distance buffer + speed step". In the servo control "intelligent control" technology, the welding technology of resistance pressure welding + double power supply independent series power supply mode is studied, and the automatic steel strip welding technology and equipment (including the modulation cutting machine, the fully automatic steel strip welding machine and the fully automatic steel strip welding machine) are studied to realize the intelligent welding of the automatic steel strip. The stability of the welding point and the welding shear standard meet the technical requirements, and a set of intelligent welding technology for steel strip in mine is formed, which can be used for reference for the upgrading and application of other mining steel strip welding technology.
