What are the uses of welding nails?( Which are the sizes of welding nails?)
Cheese head studs for arc stud welding :
Cylindrical head welding nail is a cylindrical head welding nail for arc stud welding, which is a kind of fastener with high strength and stiffness connection. It is mainly used in large public buildings and super high-rise buildings, and its main body is mostly steel-reinforced concrete structure. In order to make steel components have good bonding force and work together, the cylindrical head welding nails of fasteners are widely used in this field. Through many experiments and engineering applications.
Use of round head welding nails:
Industrial plant construction, highway, railway, bridge, tower, automobile, energy, transportation facilities construction, airport, station, power station, pipeline support, lifting machinery and other types of steel structure engineering.
Wholesale factory prices. Good price, good quality. Your inquiry is welcome.Precautions before using welding nails:
1) Before welding, the welding nails should be checked to ensure that there is no corrosion, oxidation, grease, moisture or other defects affecting the quality of welding.
(2) The porcelain ring used for welding should be kept dry, if the porcelain ring is damp due to the damage of the packaging, it should be dried before welding, the drying temperature is 120ºC, and the heat preservation is two hours.
(3) There should be no harmful substances such as oxide, rust or moisture that affect the quality of welding within 50mm of the welding site of the welding nail.
(4) When the length of the feed wire is less than 50mm, its cross section should not be less than 35mm2; At the same time, it is necessary to use a dedicated power supply with sufficient capacity, its capacity is generally 100KVA - 150KVA, and should be rain and sun protection, the distribution box should be near the plug welding machine, so as to quickly cut off the power supply when there is a failure. The minimum distance between the welder body and the wall or other obstacles is 20cm to ensure that the air flow around the welder is conducive to heat dissipation.
