However, only spot welding can be carried out for welding, and effective welding cannot be achieved in the case of oblique intersection. At the same time, with the influence of concrete pouring, building settlement, horizontal displacement, etc. after welding, the lattice columns will settle and shift under the influence of the connecting steel bars, affecting safety and normal use.
