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.
