This paper presents an experimental investigation and a numerical modelling of the FSW process in order to analyse the influence of different welding parameters on the horizontal welding force
The important factors for maintaining consistency and a good seam weld nugget formation are, the welding force
, welding current magnitude, welding speed, electrode shape and the mode of the current being supplied .
The experiment was conducted in a weld-time mode and the welding force
was set to 145.
The paper seeks to highlight the important influence in the ultrasonic joining process of a secondary technological parameter, the sonotrode active surface geometry, together with basic energetic parameters of the ultrasonic welding process such as welding time, welding force
, and ultrasonic micro vibrations amplitude.
A new low-profile, resistance welding force
sensor measures positive and negative weld tip forces, using the manufacturer's WeldThrough technology, and can withstand thousands of amps of current.
However, these papers did not investigate the welding force
which occurs during FSSW.
But in our model, the direction of chains moving is mainly imposed to the same direction of the welding force
The new system uses an electric stepper motor with optical encoder, a rigidly mounted booster, in-line load cell for precise welding force
, and a linear ball-screw actuator.
To study the effect of welding time, the welding force
Load cells with force gauges can be used to verify and calibrate welding force
This apparatus is also called as high-speed welding nozzle, which is widely used to heat surfaces intensively, to apply welding force
sufficiently, to accelerate welding speed, and to facilitate the process for a welder .
System controls temperature and speed, freeing operators to focus on welding force
