In our country, the load-bearing structure of high-rise buildings mostly adopts rigid columns, that is, external steel bars wrap concrete, and the concrete layer on the surface of steel structure columns is connected with studs to increase the connection area. Increase the shear strength of the contact surface, so that the steel column is firmly combined with the concrete surface and bears the same force.
Stud welding method: turn on the torch power supply machine, put the cylindrical stud on the torch to prevent the arc seat ring, start the torch, the current melts and the seat ring produces arc light. After a short time, tighten the end of the cylindrical stud substrate at a certain speed to melt it, and cut off the power supply.
Stud bolts are welded and fixed on the base material. This method is also called stud welding. Stud welding is a method of contacting one end of a stud with the surface of a plate or tube to generate an arc. After the contact surface melts, a certain pressure is applied to the stud to complete the welding.
Cylindrical head welding nails are suitable for high-rise steel frame buildings, industrial workshops, highways, railways, bridges, iron towers, automobiles, energy sources, transportation facilities, airports, stations, power stations, pipe supports, lifting machinery and other steel structures.
