It was determined that process time was dominated by the cleaning step force parameter, torque was dominated by welding distance and welding force parameters, head height and underhead fill were dominated by welding distance parameter, and weld zone diameter was dominated by cleaning and welding force parameters.
In the event an operator's fingers or hands blocks the movement of the electrode, Soft Touch will not detect continuity and the electrodes will open automatically, not going into riveting or welding force. Electrodes only increase to full force after contacting the metal part being welded or riveted.
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 [1].
The experiment was conducted in a weld-time mode and the welding force was set to 145.5, 236.6, and 360 N.
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. These minor chains hauled by others also can haul chains around in WPs to move in the same direction because they are also suffered from a powerful Vander Waals force or a superposition coil conformation.
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 (4.9 N, about 0.12 MPa) was set at low level.
Load cells with force gauges can be used to verify and calibrate welding force.
