Why welding is not stable

Sources: haili    pubdate: 2016/5/14 10:19:10
A lot of reasons for welding instability of ultrasonic hand welder:
1, the voltage to be stable;
2, the pressure should be stable:
3, die for a long time the frequency deviation can also cause welding instability;
4, the machine itself caused by fault: substitution;
5, and then your welding material is not very good;
Ultrasonic power is not stable, mainly depends on the welding machine generator (box) and the matching of the transducer with the generator of the stability of the electronic device.
If installation is the way, the welding of a few points:
First, the design power is not enough;
Two, parameter debugging is not reasonable;
Three, welding tool head of the welding surface and mold contact surface is uneven;
Four, welding machine power or transducer problems or design is not reasonable;
Five, appropriate to increase the pressure of welding.
If that's the way it is:
First, after a period of work, the working point drift, need to adjust;
Two, welding materials, whether there are changes, such as material, thickness, size, etc.;
Three, welding tool head of the welding surface and mold contact surface to re adjust;
Four, welding machine power or transducer damage;
Five, appropriate to increase the pressure of welding;
Six, the performance of the transducer is too large, the replacement of the welding transducer.
