What is projection welding? [PW01]
Projection welding is an evolution of spot welding, that is, a projection point is pre-set on the workpiece, and one or more nuggets are formed at the projection point in turn during projection welding.

Advantages and disadvantages of nut projection welding [PW02]
The nut projection welding is one kind of resistance welding method. One or more projection points are pre-processed on the bonding surface of a nut generally. The nut will be contacted, pressurized to the surface of another workpiece. Next electricity goes through them and heat them up. After the projection points are crushed, these contact points form solder joints. Projection welding can be used instead of spot welding to weld small parts to each other or to weld small parts to large parts.

What is nugget? How does nugget form? [DCS05]
The nugget formation process of intermediate frequency welder can be summarized as placing the welding piece between two electrodes, increasing electrode pressure, and releasing strong welding current to the welding area by the resistance welding transformer, which creates a real physical contact point on the weldment contact surface.

How to set the current parameters of mid-frequency welder? [DCS06]
Welding current is an important parameter of mid-frequency welder, the penetration of nugget depends on welding current. Assuming the other values are constant, increasing the current without increasing the strength of the solder joint will increase the rate of welding. Assuming the other values are constant, increasing the current without increasing the strength of the solder joint will increase the rate of welding.
