How can the spot welder adjust the relationship between welding strength and each data?
Your spotwelder voltage is fixed or adjustable, a fixed voltage, if, according to the thickness, if the weld of 0.8mm+0.8mm plate, 16 pressure and 16 pre pressure welding of 12 to maintain 12 endless 12, there should be a regulation, increase the heat, slowly, after welding, twist welding, it would not fall off. Two, voltage adjustable, the voltage transferred to level 7 or 8, the parameter is similar to the above
Say how to adjust, what is the adjustment? Is it resistance welding?
The main adjustment parameters of the spot welding machine are current and power time. Other preload time, maintenance time and intermittent time are not very important, but only some auxiliary parameters;So with the plate thickness increasing need to increase the current, and increase the current way is generally used for regulating voltage mode (resistance under a certain voltage, the higher the current greater), or constant current state of increased power on time, and can also increase the amount of heat input, so as to obtain good welding effect;Spot welding is generally divided into two kinds: hard specification and soft specification. Hard specification means high current + short time. Soft specification is small current + long time
