Anodisers and Selecting the Appropriate Aluminium Filler Material
Of all kinds of metal in use today, aluminium has become a vital cornerstone in the fabrication, metalworking, and welding industries. Using it for welding can be a challenge because some rules that apply to mild steel do not apply to aluminium. There are some factors to be considered when selecting a filler alloy and welders should consider whether the part will be given to professional anodisers to enhance its properties and meet specifications. Anodising works by immersing the aluminium in an acid electrolyte bath where an electrical current is passed through, creating a coating of aluminium oxide and thus creating an extra durable layer for the aluminium under it.
