Abstract

The invention discloses a modulating pulse current welding method and system of an aluminum alloy thin plate and a storage medium. The method comprises the following steps that based on the standard formula of the parabolic function, the welding peak current is calculated, and welding parameters are configured; and welding operation is started based on a preset parabola curve according to the welding peak current obtained through calculation and the configured welding parameters. According to the ladder single pulse current welding method achieving modulating through the parabolic function waveform, the effect of a strong and weak pulse group stirring molten bath is formed, and bubble escape is facilitated; and in addition, the ladder waveform has the globular transfer control stage, globular transfer regularity in the welding process is high, welding seam formability is good, the good welding seam forming effect is achieved on welding of the aluminum alloy thin plate, and the method and system can be widely applied to the technical field of metal welding.

Description

technical field [0001] The invention relates to the technical field of metal welding, in particular to a modulation pulse current welding method, system and storage medium of an aluminum alloy thin plate. Background technique [0002] Compared with ordinary ferrous metal materials, aluminum alloy materials have the characteristics of light weight, high strength, small specific gravity, good corrosion resistance and convenient recycling. Wide range of applications. However, compared with conventional ferrous metal materials, the physical and chemical properties and welding process performance of aluminum alloy materials have their own significant characteristics, and the difficulty of welding has always been the biggest obstacle restricting its wide use. The characteristics of aluminum alloys make it easy to form welding defects such as slag inclusions, incomplete fusion, incomplete penetration, shrinkage cavities, thermal cracks and hydrogen pores during welding.
