Abstract: [Objective] The objective of this study is to improve the one-way anti-shedding mechanism of traditional submerged arc welding flux to improve the welding efficiency of small-diameter cylinders. [Method] By analyzing the welding defects of small pipe diameter products, a flux anti-detachment device was added to the submerged arc welding machine gun side, and a side plate mechanism with automatic opening baffle plate, rotating replacement of different diameters, and a width adjustment mechanism of the left and right support plates were designed and applied to form an enclosure mechanism to realize the cylinder welding of different diameters and different grooves, so as to ensure the effective supply of flux during the welding process, so as to improve the welding quality of the cylinder barrel. [Result] The optimized flux anti-detachment device was applied in practice, and the welding quality of the product was increased by 20%, and the welding quality was more stable. [Conclusion] It can effectively expand the application range of submerged arc welding, improve the welding efficiency of pipe with different diameters, and provide reference for the application of curved surface welding.
