Type U3 projection weld stud parameter

Type U3 projection weld studs can be used to fix trailer wiring harnesses. They can solve the problem of cable ties getting stuck in the trailer wiring harness. Weld them directly to the trailer frame every 12 inches. Its annular welding ring melts thoroughly and the welding speed is fast. The clamp-on wire harness fixture is fixed on the stud without the need for drilling. On rough roads, its seismic performance is better than that of bonded supports.

Type U3 projection weld studs are used for the construction of solar panel brackets. If you want to install solar rails on a thin corrugated roof, they can prevent leakage. Weld the solar rail through the roof panel to the purlin below. Hot-melt sealing can prevent water from seeping in. Fix the guide rail directly to the studs with bolts.

Type U3 projection weld studs for conveyor rail fixation. The guide bolts on the thin frame have fallen off, so you can use it to reinforce the bracket. Weld along the frame every 18 inches. Fix the guide rail to the studs with bolts. Reduce the downtime in food factories caused by thread detachment.

Welding

Type U3 projection weld studs during welding, the three protrusions below the head can fully contact the surface of the workpiece. Through the heat generated by the welding current, the protrusions and the workpiece quickly melt and fuse together, forming a very stable connection that can withstand considerable tensile and shear forces.
