Metal fixings

Compatibility of metals, welding, and brazing

Joining metal components, whether to make a railing, structure, gate, or seat, requires careful thought. Joining different metals can lead to corrosion. Welding, riveting, and the use of nuts and bolts are classic ways of joining two components and all are subject to problems. Welding can be very clumsy and weak if it is done without skill, while rivets and bolts need to be of compatible metals.

Galvanic and electrolytic activity, rusting, and staining

Galvanic (or electrolytic) corrosion results from dissimilar metals coming into contact, and the consequent flow of electrical current. An electrolytic medium—e.g. water, and especially salt water—speeds up the process. If dissimilar metals are to be used, separate them by means of a neoprene gasket or washer, by fabrics, or by the use of paints. Never place different metals touching without checking their compatibility. Ideally, make all components from the same metal.
