Product Description
Stud welding involves contacting the stud end with a plate (or pipe fittings) surface, creating an electric arc to melt the contact surface, then applying pressure to complete the weld. Arc stud welding with cylindrical head studs is ideal for:
- High-rise steel structure buildings
- Industrial plant buildings
- Highways, railways, and bridges
- Pylons, automobiles, and energy facilities
- Transport facilities, airports, and stations
- Power stations and pipeline supports
- Cranes and other steel structures
Welding Methods
Stud welding includes various methods: arc welding stud welding, energy storage stud welding, resistance welding, and projection welding. Each method requires specific equipment like arc stud welding machines, energy storage stud welding machines, resistance welding machines, or convex welding machines.
Capacitor Discharge Stud Welding
This method uses large capacity capacitors as the energy source, controlled by SCR for precise discharge timing. It melts the stud tip instantly with low voltage and strong current, merging it with the work surface in 1-10ms for a firm weld.
Stainless Steel Advantages
Compared to carbon steel, stainless steel fasteners offer superior performance:
- High Temperature Resistance: Maintains performance under heat with strong anti-oxidation properties
- Electro-Negative Rate: Five times higher than carbon steel wire, with expansion coefficient that adjusts with temperature
- Stress Capacity: Meets daily industrial requirements while not matching high-strength bolts
- Mechanical Properties: Excellent rust resistance and corrosion resistance inherent to stainless steel
316 Stainless Steel Characteristics
Advantages:
- Enhanced corrosion resistance in chloride environments (marine, chemical, pharmaceutical applications)
- Superior high temperature strength and oxidation resistance compared to 304 stainless steel
- Excellent mechanical properties including strength, plasticity, and toughness
- Good weldability with various welding methods
Disadvantages:
- Higher cost due to molybdenum content
- More difficult machining requiring higher cutting forces
- Requires clean production environments
