What is Electrojoining

A common task in engineering - permanently joining two or more components - is often accomplished by welding, brazing or soldering.

However, this is challenging when: the articles being joined are made of materials that can not be welded, the presence of solder material in the joint is undesirable, or one of the items is non-metallic.

Adhesives can be used in such cases, but the joint then does not provide electrical or thermal conductivity, and often is not as durable and mechanically strong as a metal joint.

Electrojoining is a plating technique, in which two or more items are permanently joined by a tightly adherent band of electroplated material, 'fusing' the components together. Exceptionally strong mechanically, such joints, when properly executed, are also hermetically leak tight, thermally and electrically conductive.

The added benefits of this joining method are:

• low (<120°F/°50 C) temperature of all operations - no heat affected zone that often compromises metal strength
• a choice of materials that can be used in the joint - NiColoy®, Nickel, Copper, and their combination
• ability to join dissimilar or non-conductive materials that can not be welded, soldered or brazed
• ability to join very thin (.001"/25 micron) components - bellows, electroforms, etc.
