Aluminum Welding has become a very popular method in welding and machinery over the years. If you look closely, aluminum is the ideal substrate for manufacturing companies for building trailers and truck bodies. In fact, it has been rightly called the ‘wonder metal’ – a metal that was once more valuable than gold…But, why? Well, for one, experts prefer it more as compared to other metals.
This is because it has a light weight, which results to fuel savings. It is strong, flexible, corrosion resistant and conductive of heat and electricity. The metal is not affected by the magnetic powers as well. Naturally, aluminum fabrications can be used in areas where other products can’t be used.
However, there are some minor problems that aluminum fabricators face when they work with this metal. Case in point is how the metal has a high thermal conductivity meaning it transfers heat very quickly. This is why there is a greater chance of getting it burned during the fabrication process – burn-through. Also, the metal has a low melting point and is very flexible, which causes it to warp. These problems among others are usually a challenge even to experienced aluminum fabricators and so they are forced to use a different methodology for aluminum welding and fabrication.
Aluminum Welding is becoming more prevalent these days
Aluminum welding depends upon knowing the strengths of the metal as a material because that knowledge is important to the success of every project. But still, aluminum welding and fabrication require special consideration since fabrication has been a challenge before even when joining materials of different thickness.
But worry no more, with the new automation method things have become easy for metal fabricators and there is increased productivity…For quick fabrication and welding, it is great to have a mechanized welding process. But, for extensive welding, it is best to use the upgraded gantry system with seam tracking. Seam-tracking helps to adjust the soldering iron and ensures that it stands correctly by using mechanical or laser sensors. And the end result? Faster and more accurate welds. No lugging anymore!
Another less common fabrication process is the use of robotic arms, also known as flexible automation. This is the use of robotic systems with the robotic arms which can not only perform small welds or be used in sub-assembling the trailer but also in performing longer welds, as this method is known to offer increased output.
Aluminum then can be turned to various parts and shapes for an incredible variety of functions by casting the molten metal to take the shape of a particular mold; rolling it into thin foils; forging by shearing (pressing/punching) to a super strong metal for airplanes and automobiles; extruding; drawing; and machining by sawing, milling, turning, boring and tapping/threading to produce bolts, screws and other small pieces of hardware. Not to forget, by insulation and hydro-forming. I mean, aluminum is known to be highly malleable.
All in all, aluminum is an attractive metal and often requires no finish. But it can be polished, painted and electroplated. Now you can become a better MIG and TIG welder…
