Today’s advanced technology makes plasma cutting aluminum quick, affordable and easy. Using the best equipment and understanding the process and requirements for cutting aluminum will lead to excellent results.
Proper gas selection is essential when plasma cutting aluminum. Cutting aluminum with air creates a rough edge coated with aluminum oxide. Using different gases, such as nitrogen or argon mixes, will produce better results with aluminum. Water-mist shielding is an excellent choice for aluminum. Today, plasma cutting systems can cut at very high speeds per amp, which minimizes the amount of heat input into the cut edge. This makes plasma cutting aluminum more effective, with better results, than ever before.
Plasma cutting aluminum can offer significant advantages over laser cutting aluminum, depending on the thickness and volumes needed. Plasma cutting is much more cost-effective, with lower equipment and operating costs.
A major consideration when cutting aluminum is excess hydrogen buildup. If using a water table, caution must be taken to ensure that explosive gases do not build up in the water table. This can be accomplished by lowering the water level to 2” BELOW THE BOTTOM of the aluminum plate and keeping it at that level during the cut and for several hours after the cut. Submersed aluminum can continue emitting hydrogen fumes long after cutting is complete. When your next cuts are MS the water level should remain lower to allow all gas fumes to escape. If you cut a lot of aluminum, a bubbler can be installed in the bottom of the water table to agitate the water and release the gas. Another option could be using a downdraft cutting bed. CAUTION: Your filtration system must be designed and rated for combustible gasses!
When selecting the process for cutting aluminum, manufacturers need to prioritize their needs. For some operations, productivity may be the number one concern, while others may regard edge quality as the most important issue.
