Type T3 projection weld studs are a type of connecting piece used for welding and fixation. It is a metal rod with threads throughout its length, and at the head there are several small protrusions, which are crucial during the welding process. There are also various lengths available.
T3 projection weld studs are used to repair the rusty truck body panels. They can simplify the maintenance process. Attach it to the thin base plate. The tip can burn through the rust, achieving a secure weld. The new fixed guide rail can be directly fixed to the stud using bolts. There is no need to drill holes in the fender or install nuts.
Type T3 projection weld studs are used in the manufacturing of aluminum marine guide rails. They are suitable for marine alloys and can be used as anti-corrosion guide rail supports. By using the low-temperature setting, welding can be carried out through the side of the hull without warping. Screw the stainless steel guide rail onto the screw stud on the deck above. It is more resistant to salt spray than threaded joints. The drilling will not cause leakage.
T3-type projection weld studs are used to reinforce the metal stair treads. They can be used to add grip strips. Weld through the toe cap every 6 inches. Attach the anti-slip rubber directly to the stud using bolts. Spot welding can penetrate the oxide layer on old staircases. It can pass the OSHA anti-slip test without the need for sanding.

The most distinctive feature of type T3 projection weld studs is the protruding design at the head. The protrusions are of uniform size and can precisely contact the surface of the workpiece during welding. When the current passes through, the heat is concentrated at the protrusions, which melt and fuse with the workpiece. After welding, the threaded column and the workpiece are closely attached with almost no gap.
