3) Pressure parameters
Selection and adoption of pressure parameters often relates to such factors as the
welding area and the material of the weldment, and the amplitude of welding head, etc.
The pressure parameters exert direct influence on the output load of the welder.
Generally, the higher for the pressure, the higher output load. However, over-high
pressure will cause overload protection or reduction of effective output. Therefore,
pressure parameters shall be selected as appropriate. For common small work pieces
or non-crystallized materials such as ABS, start adjustment from 0.2MPa; for larger
work piece or semi-crystallized materials such as polypropylene, polyethylene, or the
weldment with higher requirements for sealing, start adjustment from 0.4MPa.
4) Parameters for weld time
Weld time is the time for outputting the ultrasonic welding power, which influences the
quality of welding directly. Just like the pressure parameters, its selection relates to
such factors as the welding area and the material of the weldment, and the amplitude
of welding head, etc. Generally, too short weld time will lead to insufficient weld
strength, while too long weld time will exert negative effect on the appearance of the
weldment. Actual selection shall be determined by means of testing.
In practical application, the influences of the pressure parameters and the parameters
for weld time on the weldment are a couple of correlative factors. Moderately higher
pressure will shorten the weld time; vice versa, to achieve longer weld time, lower the
pressure appropriately.
V. Precautions
for
Application
1. User shall not alter welding head at option, or it may change frequency
parameters of transducer system, which will result in damages to transducer
system and ultrasonic power generating system.
2. Never leave both hands under the welding head when the machine is in operation
or is testing ultrasonic sound, to guarantee operating safety for operators!
3. No direct contact is allowed between the welding head and the machine base or
other metal fixtures during operation or test, to ensure safe operation of the
equipment;
4. No start-up or operation of this equipment is allowed before reliable connection to
earth!
5. Start-up or operation is prohibited where high temperature and high dust
environment exist!
6. Stable operational power supply is required while operation beyond the rated
voltage is prohibited!
7. Earplugs are recommended for a long-term operator to avoid injury by noise
