Influence of welding time of energy storage welder on welding quality [CD06]
Dec 26,2023
The longer the welding time or power on time, the more heat will be generated, the larger area of heat diffusion and the larger area of possible deformation of the workpiece.
In order to ensure nugget size and solder joint strength, welding time and welding current are able to complement each other in a certain range.
In order to obtain the solder joint with a certain strength, you can use either a high current and short time (strong condition) , or a low current and long time (weak condition) . The choice of strong or weak condition depends on the properties and thickness of the metal, as well as the power of the welder used. There is an upper and lower limit for the current and time required for metals of different properties and thicknesses, and this is the standard for use.
For a given workpiece material and thickness, the welding time is determined by welding current and projection stiffness. In projection welding of low carbon and low alloy steels, welding time is secondary to electrode pressure and welding current. After the suitable electrode pressure and welding current are determined, the welding time is adjusted to obtain a satisfactory solder joint.
If you want to shorten the welding time, you have to increase the welding current, but too much welding current may cause metal overheating and spatter. Usually the welding time of projection welding is longer than that of spot welding, the welding current of projection welding is lower than that of spot welding.
