Tantalum Indenter for Increased Weld Strength in Low Density

Component InterTechnologies (CIT) has been welding pressed tantalum anodes for the capacitor industry since 1980. Over time, the demand for more performance the volume per capacitance ratio increased less and less dense powders were being welded the riser wire. At some densities the compressed pellet to anode wire weld was not strong enough to withstand the rigor of the manufacturing process.
To address this problem the pellet needed to be compacted at the weld area only, without compacting the entire pellet that would reduce performance. This compacting process needed to be done in a localized area and at production speeds (12000 pph) .
CIT designed a completely new pellet feeding welding system that incorporated a carbide tool for the compacting a very small area of the pellet that the anode wire is welded into. This provides a more dense area that when the wire is welded into is much stronger and will withstand the rigors of later manufacturing process.
