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 aluminium sheet.
A couple of electrodes at the same time clamps the work pieces jointly and delivers the electrical current wanted to make the weld.
Vehicle manufacturers use resistance spot welding in the factory.
Typically the sheets are in the 0 5 to 3 mm thickness r.
The welding schedules electric parameters of welding electrodes materials and electrodes life time by resistance spot welding aluminium were.
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.
Share this trick and if.
Resistance spot welding is the joining of overlapping pieces of metal by applying pressure and electrical current.
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 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.
In this article the comprehensive summary concerning technology of resistance spot welding of aluminium alloys was presented.
Spot welding is a procedure in which two metal surfaces are melted jointly to form a weld.
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.
The aluminium alloys are more frequently used in automotive industry especially as an alternative material for car bodies.
