Dissimilar Materials Welding
RF and Impulse welding systems are typically capable of welding materials that have chemical compatibility and similar melt points. Dissimilar Materials Welding allows for traditionally non-compatible materials to be joined with weld strengths that are as reliable as those of compatible materials.
How it Works
A material that is compatible with both the substrates and the welding process is bonded to the parts. This tie layer is then welded to both of the non-compatible substrates, thus tying the materials together.
Biocompatibility requirements restrict the kinds of materials that can be used in regulated medical products. When approved materials are not compatible, but have the desired properties, alternate forms of attachment are required. The Dissimilar Materials Welding process makes these joints possible and often more reliable.
