Spot Welding Aluminium Sheet

Spot welding is a procedure in which two metal surfaces are melted jointly to form a weld.

Spot welding aluminium sheet.

Spot welding is a type of electric resistance welding used to weld various sheet metal products through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. Resistance spot welding is the joining of overlapping pieces of metal by applying pressure and electrical current. Vehicle manufacturers use resistance spot welding in the factory. Spot welding uses the heat from an electrical current to join 2 pieces of metal quickly and is typically used for joining sheet metal.

The welding schedules electric parameters of welding electrodes materials and electrodes life time by resistance spot welding aluminium were. Share this trick and if. In this video lazze shows how you can spot weld aluminum with a standard 220 volt spot welder that is probably already in your shop. In this article the comprehensive summary concerning technology of resistance spot welding of aluminium alloys was presented.

A couple of electrodes at the same time clamps the work pieces jointly and delivers the electrical current wanted to make the weld. When comparing similar thickness materials the static and fatigue shear strengths of aluminium alloy spot welds are about one third the value of steel welds depending on the alloy type. Where aluminium is used instead of steel its gauge is normally increased giving weld strengths which compare more favourably with those of steel but still enabling weight savings to be made. These joints created by resistance spot welding form a button or fused nugget resistance spot welds are found typically on flanges staggered in a single row of consecutive welds.

Work pieces are held together under pressure exerted by electrodes. Spot welding also known as resistance spot welding is a resistance welding process. This welding process is used primarily for welding two or more metal sheets together by applying pressure and heat from an electric current to the weld area. It s also easy to do with a spot welding machine which has 2 electrode tongs about 6 inches 15 cm long that pass an electrical current through the metal to fuse them together.
