Spot welding aluminium sheet.

Resistance spot welding is the joining of overlapping pieces of metal by applying pressure and electrical current. 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. Spot welding is a procedure in which two metal surfaces are melted jointly to form a 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.

Spot welding uses the heat from an electrical current to join 2 pieces of metal quickly and is typically used for joining sheet metal. Vehicle manufacturers use resistance spot welding in the factory. 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. Spot welding also known as resistance spot welding is a resistance welding process.

Work pieces are held together under pressure exerted by electrodes. A couple of electrodes at the same time clamps the work pieces jointly and delivers the electrical current wanted to make the weld. Share this trick and if. The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets together.

The aluminium alloys are more frequently used in automotive industry especially as an alternative material for car bodies. Typically the sheets are in the 0 5 to 3 mm thickness r. 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. 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.
