In this study, an equation for adjusting the parameters affecting the flare of the weld on the welding product was established. Based on the empirical research results, the factors affecting welding flux after using bending machines have been studied. It has showed that the factors like the press force, the welding mode, the welding current, and the welding time were the main factors afftecting directly the flaration of the weld. For the standard of the flare of the weld of 3.3 mm, the welding current was 22A, the welding time was 5 deci-seconds, and the press force was 2.78 Kg/cm2. The results showed that the automatic steel-wire welding after improving the welding machine and mode had a productivity of 5.8 times higher and reduced 20% of energy consumption compared to traditional welding methods. Compared with unmodified automatic welding, the productivity increased by 5.8%, energy decreased by 7%, and the weld quality was more stable.
