M5 M6 Stainless steel Weld Stud Bolts with Nuts Washers SUS304 SUS316 A2-70 A4 Welded stud

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.

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.

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.

• High Temperature Resistance: The hardness of stainless steel fasteners is strong enough, with strong anti-oxidation ability, and can work properly at high temperatures.
• Electro-Negative Rate: Stainless steel fasteners have a high electro-negative rate, about five times higher than carbon steel wire. The expansion coefficient increases with temperature.
