When the steel bars are welded, the two steel bars are mutually fastened, the acting force between the two steel bars is controlled as follows,
after the cross-shaped steel bars are welded, the mutually connected positions are melted, the section thickness is reduced by Delta s, in the innovation, the steel bars are mutually clamped, the mutual clamping force is proper, and the force applied to the steel bar span is enough
Controlling, wherein the stress N = P/2 at two ends of the steel bar, assuming that the fusion of the interconnected steel bars is completed within t time, when the steel bars are initially added, the stress N = P/2 at two ends of the steel bars, during the fusion process, the device ensures that the numerical value of the stress N at two ends of the steel bars is changed into 0 within t time, the fusion is completed, the fusion part is in a natural stress state, wherein E is the elastic modulus of the steel bars, I is the section inertia moment of the steel bars, and l is the welding distance of the steel bars. The principle is that before the steel bar welding, the steel bar is deformed into delta s, the two steel bars are integrated with each other along with the melting of the cross welding, the delta s generated by the pre-bending disappears, the internal stress of the steel bar disappears, and the steel bar is naturally straight.
