Therefore, composite floors are mostly adopted for floors.

[0003] The fixation of profiled steel sheets and steel bar truss floor decks to steel structures is basically achieved by stud penetration welding. After the laying of profiled steel sheets and steel bar truss floor decks in the project is completed, first, lines are drawn according to the positions of the lower steel beams, and operators use stud welding machines and porcelain rings for welding. According to the construction methods of most current projects, the stud welding work generally needs to be completed by two people. One person places the porcelain rings and studs in advance according to the marked positions and spacing, and the other person holds the stud welding gun head for stud welding. Since stud welding requires inserting the cylindrical head of the stud into the welding gun chuck, after adjusting the position of the welding gun to be perpendicular to the plate surface, the studs placed in advance are all horizontally placed near the welding position. The welding worker needs to hold the stud and align the cylindrical head with the welding gun chuck and insert it into the chuck under the action of a vertical force.
