Soldering is recommended for making connections on electrical circuits, but it should never be used where strong joints are required. For permanent joints between two dissimilar materials like nylon and metal, it is advisable to use adhesives. For temporary jobs, like fitting a maintenance cover, screw-fastening should always be used. Riveting is recommended for permanent sheet-metal joints such as outer casing fitting. Although welding should always be used for steel support girders, brazing can be used for medium-sized joints where strength is required; for example the joint between the base and body of a hydraulic jack.

Where are steels of low carbon content used?
The most important metal in industry is iron and its alloy – steel. Steel is an alloy of iron and carbon. It is strong but corrodes easily through rusting, although stainless and other special steels resist corrosion. The amount of carbon in steel influences its properties considerably. Steels of low carbon content (mild steels) are quite ductile and are used in the manufacture of sheet iron, wire and pipes. Medium-carbon steels containing from 0.2 to 0.4 per cent carbon are tougher and stronger and are used as structural steels. Both mild and medium-carbon steels are suitable for forging and welding. High-carbon steels contain from 0.4 to 1.5 per cent carbon, are hard and brittle and are used in cutting tools, surgical instruments, razor blades and springs. Tool steel also called silver steel, contains about 1 per cent carbon and it is strengthened and toughened by quenching and tempering.
