Ultrasonic Spot Welder

Product name: Spot welding machine , ultrasonic spot welding machine

The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes press the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current flows from one electrode to the other electrode When the two contact resistance points form an instant thermal fusion, and the welding current flows from the other electrode to the electrode along the two workpieces to form a loop, and will not damage the internal structure of the welded workpiece.

 Working principle of ultrasonic spot welding machine:

The process of spot welding is to open the cooling water; clean the surface of the weldment, and after the assembly is accurate, send it between the upper and lower electrodes, apply pressure to make it contact well; electrify the contact surface of the two workpieces to heat and partially melt, forming Nugget: Maintain pressure after power failure, so that the nugget is cooled and solidified under pressure to form a solder joint; remove the pressure and take out the workpiece. Spot welding process parameters such as welding current, electrode pressure, energizing time and electrode working surface size have a significant impact on welding quality.

The spot welder uses the high temperature arc generated when the positive and negative poles are short-circuited instantaneously to melt the welded material between the electrodes to achieve the purpose of combining them. The structure of the spot welding machine is very simple. To put it bluntly, it is a high-power transformer that converts 220V AC into a low-voltage, high-current power supply, which can be DC or AC. Welding transformers have their own characteristics, that is, they have a sharp drop in voltage.
