Guides and Standards to Effective Aluminium Fabrication

There are literally scores of standards utilized during aluminium fabrication operations. Is the right grade of the alloy selected, one that’ll suit its application? What about welding guidelines? Aluminium has a low melting point, so some care must be taken when welding aluminium components. What about an attractive post-finishing process? Again, there are guides and rules to regulate this part of the fabrication cycle.

Differently Graded Aluminium Alloys 

If a workshop is to effectively form aluminium parts into a desired shape, then the correct alloy family has to be selected. If the alloy is set to enter a challenging environmental locale, again, the alloy must function properly here. Otherwise, it’ll fail. It’ll corrode or buckle or lack conductivity, or the product will be too heavy. There are even food-safe aluminium alloys and marine capable material variants. Just as importantly here, some graded alloys are more formable and ductile, or they offer an essential weldability feature. For example, certain weldable grades flow better and yield more aesthetically pleasing results. Others, those that belong in the non-weldable category, crack when arc welding heat is applied. Even the type of filler rod varies, just because of a manganese or silicon additive in the alloy.

In-shop Fabrication Standards 

The above passage of text reminds us to consider the different alloy families and grades. Additives and heat treatment work are two of the more influential fabrication-impacting factors. These processing components also affect the bend radii of the formable materials. The bending process should yield superior results at all times, but if a certain grade of the alloy wrinkles or cracks, maybe it’s time to look for a ductile substitute. Likewise, weldability errors can be corrected by selecting a grade that doesn’t occupy the non-weldable aluminium category. Elsewhere, there are standards and rulings regulating the material handling stage. Rings and jewellery can score glossy aluminium sheets or remove a purpose-critical layer of aluminium oxide. Packaging and transit guides, material forming guidelines, vacuum cup positioning, and equipment maintenance/cleanliness standards, all of these fabrication impacting factors require the attention of an expert shop management team.

Safety guidelines, as always, come first. Jewellery off and boiler suits on, the floor personnel dress for business. Welders wear goggles and hard hats, and a second set of processing standards intersect. This paper ensures the provisioning department allocates the correct alloy family, one that’s both weldable and formable. Set to pass through multiple machining stations, the ductility and formability questions are answered. Finally, at the end of the day or end of a particularly gruelling project, clean and maintain the shop equipment, ready for the next job.
