How to determine a standard weld strength?
The appropriate welding data which delivers the required standard weld strengths can thus be determined (Figure 4500.02.03). 0 3 4 Analogous to the parameter settings, geometrical values like weld spot and nugget diameter as well as distance from edge depend on the material.
How much current do you need to weld aluminium?
Thus, the current required for welding aluminium is about twice that for welding steel sheets of the same thickness, and this although the aluminium alloys have a much lower melting point. The formation of the weld nugget depends mainly on the current strength, the resistance and the welding time.
What are the requirements for welding with DC?
The welding is carried out using special arrangements, and the welding procedure must always be recorded (Figure 4500.02.08). Metallurgical Influence of a Single Weld Spot on the Base Material Load Transfer = 0 Properties ( not bridge-connected ). Additional Bending = 0 Peltier Effect must be considered while Part 1 Part 5 Welding with DC.
How much energy is needed for welding aluminium?
For this reason, it is essential that the welding energy for aluminium be delivered within as short a time as possible. Thus, the current required for welding aluminium is about twice that for welding steel sheets of the same thickness, and this although the aluminium alloys have a much lower melting point.
How many weld spots are needed for ultrasonic welding?
For resistance spot welding, the number of weld spots was varied from 4 to 8 to 12 weld spots. The way the weld spots were arranged is the best approach of the optimal weld seam with the lowest electrical contact resistances. For ultrasonic welding, four sonotrodes with different dimensions were used.
