Ultrasonic metal spot welder
Jun 11 , 2021
Ultrasonic metal spot welder: It is similar to friction welding, but there are difference, Ultrasonic welding takes a short time and the temperature is lower than recrystallization; It is also different from pressure welding because the static pressure applied is much less than pressure welding. It is generally believed that in the initial stage of the ultrasonic welding process, the tangential vi...

What are the preparations before starting the automatic spot welding machine?
Dec 10 , 2021
The electrode pressure of the battery pack automatic spot welding machine has a significant effect on the total resistance R between the two electrodes. As the electrode pressure increases, R decreases significantly, while the increase in welding current is not large, and it cannot affect the decrease in R. Heat production is reduced. Therefore, the strength of the solder joint ...

What are the factors that affect the efficiency of the battery spot welding machine?
Dec 24 , 2021
●Welding current Since the heat generated by the resistance is proportional to the square of the current passed, the welding current is the most important factor in generating heat. The importance of welding current does not simply refer to the size of the welding current, the current density is also very important. ※Nugget: refers to the metal part that solidifies after the melting of the ...
