Ultrasonic welding has many advantages over traditional methods. For one, welding occurs at low temperatures relative to other methods. So, the manufacturer does not need to expend vast amounts of fuel or other energy to reach high temperatures. This makes the process cheaper. It's also faster and safer.
Preparing the Device. Collect all the components to acquire an ultrasound image. This includes a transducer, computer, ultrasound gel and the object to image. Gather all of your items at first so that you will not have to run around trying to find things. Wash your hands if they are dirty.
The process occurs in fractions of a second to seconds. So, it can be done more quickly than other methods. In fact, it can bond plastics better and faster than glues. For example, the new smart keys in cars have a transponder chip in them. The car can only start when it senses the chip. To make the key, one end of the metal key blank and the chip get placed into one half of the plastic top. The other half gets placed over them and bonded to the base half. This bonding would usually be done with glue, which takes time to cure. The same task can be done with ultrasonic welding in less than a second.
Ultrasonic welding does not require flammable fuels and open flames, so compared to other welding methods, it's a safer process. Workers are not exposed to flammable gases or noxious solvents. In electronics, copper wires are usually bonded to electrical contacts on circuit boards with solder. The same task can be done using ultrasonic welding in a fraction of the time and without exposing workers to fumes from smoldering lead solder. Although workers' hearing may be damaged by exposure to high-frequency sound, this potential danger is easily reduced by enclosing the ultrasonic welding machine in a safety box or cage and/or using ear protection.
Finally, ultrasonic welds are as strong and durable as conventional welds of the same materials -- which is just one of the reasons the method is being used in car manufacturing. To make cars lighter and more fuel efficient, auto makers are turning to aluminum as the main metal in car bodies. Ultrasonic welding can be used to bond the metal in less time and at lower temperatures than traditional welding.
Ultrasonic welding does have its limitations, though. First, the depths of the welds are less than a millimeter, so the process works best on thin materials like plastics, wires or thin sheets of metal. Ultrasonically welding a steel girder for a building would not be practical. Second, it does work best when welding similar materials like similar plastics or similar metals. As you saw with New Balance shoes, ultrasonically welding dissimilar materials requires an additional material -- in the case of the New Balance shoes, it's a film that can be bonded between the synthetic suede and the mesh.
Despite these limitations, the popularity and potential of ultrasonic welding continues to grow.
Hi,
I have constructed a 40KHz, 100W ultrasonic cleaning bath using a thick cooking pot and some off the shelf parts.
Two 40KHz transducers, part number SMBLTD45F40H, were attached to the bottom of a thick wall cooking pot using dual component Epoxy (Home Depot). It is important to mix the correct proportions so it will cure to a solid piece and not flexible as it would dampen the vibration. The ultrasonic generator used was also found at the same place (STEMINC) and it is part number SMUG100W40ND. This generator is 100W and each transducer is 70W when installed alone or 50W each when installed in parallel. You must connect two SMBLTD45F40H and the system cannot be turned ON until all connections are made and the generator is connected to the transducers ATTACHED TO THE TANK. If not, the generator will be damaged. It cost me not to pay attention to this detail!.
Connections are simple. The electrode between the two piezo rings on the transducer is the positive. So connect the positive electrodes from the transducers (in parallel) and connect to the positive output of the generator. Then connect the negative electrodes from the transducers (in parallel) and connect to the negative output of the generator.
In my build I used Glue, instead of having bolts on the bottom of the pan, You con also have bolts welded to the bottom of the reservoir. Depending on the thickness of the wall of the container you will need to check if it is feasible.
