M5 M6 Stainless steel Weld Stud Bolts with Nuts Washers SUS304
SUS316 A2-70 A4 Welded stud
Product Description:
Stud welding is the stud end and plate (or pipe fittings) surface contact, electric arc, to be melted on the contact surface, give the stud a certain pressure to complete the welding method. Arc stud welding with cylindrical head studs are suitable for high-rise steel structure buildings, industrial plant buildings, highways, railways, bridges, pylons, automobiles, energy, transport facilities buildings, airports, stations, power stations, pipeline supports, cranes and other steel structures.
Stud welding is a method of welding metal studs or other fasteners to a workpiece. There are various methods to achieve stud welding, such as: arc welding stud welding, energy storage stud welding, resistance welding, projection welding and so on. The corresponding welding machine is also different, respectively, for the arc stud welding machine, energy storage stud welding machine, resistance welding machine, convex welding machine.
Stud welder in China has a variety of informal terminology, such as
seed welder, plant welder, seed nail machine, plant nail machine,
screw welder, screw welder, and so on, are referred to the stud
welder.
Capacitor discharge stud welder adopts large capacity capacitor as
the source of welding energy, and precisely controls the discharge
time by SCR, which melts the tip of the stud quickly by
instantaneous low voltage and strong current, and makes the stud
and the working surface gap merge quickly, and welds the stud
firmly on the working surface, and the whole process lasts about
1-10ms.
Applications
Compared with carbon steel, stainless steel fasteners have the characteristics of high temperature resistance and corrosion resistance, stainless steel is also more widely used in our life, what are the advantages of stainless steel in the end?
The first point, high temperature resistance
Stainless steel fasteners high temperature resistance: it is because the hardness of the stainless steel fasteners itself is strong enough, after the production and processing of fasteners have a strong anti-oxidation ability, and it is also able to work properly at high temperatures, so it will not be subjected to high temperatures too much interference. If the stainless steel fasteners can be used after manufacturing at the same time before passivation, then its effect will become better.
The second point, the rate of electric Yin
Stainless steel fasteners electro-negative rate: the physical properties of stainless steel fasteners have a high electro-negative rate, so and carbon steel wire compared to stainless steel fasteners than its electro-negative rate is five times higher. After testing, we concluded that there is a coefficient of expansion in the fastener, if the temperature is higher, then the expansion coefficient of stainless steel fasteners will gradually increase with the temperature.
