Welding method of stage truss

The stage truss welded by truss is beautiful and beautiful, while the top wire welded truss looks very "ugly", and in terms of force, the wire welded truss has uniform force points and more scientific force, which is not easy Deformation, compared with fatigue limit and strength coefficient, are very high.

Down-wire welding is relatively expensive, because with top-wire welding, workers can weld 30 pieces per hour, and down-wire welding can only weld 20 pieces, so the wire welding form is slow, so the truss of down-wire welding is slow. Compared to top wire welding trusses are much more expensive.
