Aluminium alloys are often used due to their high strength-to-weight ratio, corrosion resistance, low cost, high thermal and electrical conductivity.There are a variety of techniques to join aluminium including mechanical fasteners, welding, adhesive bonding, brazing, soldering and friction stir welding (FSW), etc. Various techniques are used based on the cost and strength required for the joint.
The benefit of welding as a joining process for steel is that it creates a bond that is almost always stronger than the components it is joining. This is why welding can be used to join the seams of pressure vessels and used to perform complete joint penetration welds on structural components that require high tensile strengths.

Friction stir welding (FSW) is a solid-state joining process that uses a non-consumable tool to join two facing workpieces without melting the workpiece material.
The storied industrial stock closed Tuesday nearly 10% higher in price on the back of the news. This was its most significant one-day gain in 2024, and was a sharp contrast to the 0.4% drop of the ...
LME Aluminium (or LME Aluminum in American and Canadian English) stands for a group of spot, forward, and futures contracts, trading on the London Metal Exchange (LME), for delivery of primary Aluminium that can be used for price hedging, physical delivery of sales or purchases, investment, and speculation.

Exothermic welding, also known as exothermic bonding, thermite welding (TW), [1] and thermit welding, [1] is a welding process that employs molten metal to permanently join the conductors. The process employs an exothermic reaction of a thermite composition to heat the metal, and requires no external source of heat or current.
