Energy storage welding nails on round tube

What is the maximum size of a welded tube?

Also, the size of the parts to be welded is limited. Possible diameters probably range from 5 to 254 mm . The largest tube diameter that is welded until now is 121 mm, larger sizes have not been tried due to a lack of demand . The maximum size is limited by the cost of the machine, which increases significantly for larger diameter workpieces.

Can tubes and sheets be Weld?

Only tubes and sheets are possible to weld until now. The size of the tubes is limited. The process only works with a high conductive tube materials. The process is not suitable for in-field applications. The process is very sensitive to changes in process parameters.

Why do welded tubes have a larger diameter?

The use of larger diameter tubes implies that there is more material which needs to be deformed and accelerated. As a result, for a larger diameter, a higher energy level is required. The diameter of the tubes to be welded is limited by the size of the field shaper.

How does magnetic pulse welding work?

In magnetic pulse welding, electromagnetic forces are used to impact two materials against each other at high speed. A power supply is used to charge a capacitor bank; when the required amount of energy is stored in the capacitors, it is instantaneously released into a coil.

What is the bonding process in explosive welding?

The conclusions regarding the bonding process in explosive welding learn that, if the velocity is too low, the impact energy is insufficient to initiate bonding. On the other hand, when the velocity is too high and reaches supersonic values, no jet force will occur and the materials will not bond.

How does thermal conductivity affect welding process?

The material thermal conductivity has no influence on the welding process itself, but it can influence the formed interlayer between the two materials. During the welding process, the eddy currents will generate Joule heat in the flyer workpiece, proportional to i2/σ, with σ being the thermal conductivity.
