Most beam column splicing nodes adopt a bolt splicing and field welding mode. Welding residual stress always exists after welding in the welding process, and a welded part is easy to generate quenched martensite and crack under the condition of high carbon content due to rapid cooling of a heat affected zone; the defects of air holes, slag inclusion, incomplete fusion, incomplete welding and the like are easily caused because the control is not in place in the welding process. And the field welding consumes long time and has low working efficiency. The bolt connection usually requires a large cost of workers during construction, and the bolt connection is difficult to be applied to the beam-column connection of the closed section due to the process problem of the bolt for the column of the closed section.
