Collect the problems existing in the use of ultrasonic metal welding equipment

For many companies that buy our equipment, they often ask many questions. The problems and solutions summarized by our engineers are as follows.

What is the welding joint material of ultrasonic metal welder?

The welding head (mold) of general metal welding machine is made of 45 steel through special high temperature heat treatment process, and there are also titanium alloys. The price gap between the two is large. Of course, titanium alloys are more durable in terms of performance. Metal die steel

When choosing ultrasonic metal welding machine, is the higher the power the better?

Of course, the higher the power, the better, but according to the size of the plastic welding surface, how much power is needed to determine the ultrasonic plastic welding machine! Different products have different power options. Small parts can be welded with low power, fragile parts can also be welded with low power, such as 35K. For difficult to weld materials or large parts, high-power welding can be considered. In addition, the quality of the machine does not divide the power. It is better to use high-power machines to weld more complex products.

What are the causes and solutions for the power board of ultrasonic metal welding machine that is always easy to burn out?

The ultrasonic welding machine always burns out the power board. The reasons are: first, short circuit, second, leakage due to poor insulation, and third, poor quality of the power board. It can be solved through three-point overhaul.

Does ultrasonic metal spot welding generate heat?

The welding joint will generate heat when working, which is caused by the mechanical loss of the material itself and the heat conduction of the weldment. The standard to judge whether the heat of the welding joint is normal is that under no load (i.e. no contact with the workpiece), the ultrasonic wave should be continuously emitted for more than half an hour, and the temperature should not exceed 50-70 ℃. If heating occurs, the welding head is damaged or the material is unqualified. It needs to be replaced.

Can aluminum foil and copper foil be welded together?

Aluminum foil and copper foil can be welded together with ultrasonic metal spot welder! Ultrasonic metal welding machine can be used for more than one and a half years, unless the mold is worn, if the manufacturer can operate normally.
