You can improve a fiber laser blanking’s cut edge by optimizing the assist gases and taking advantage of updated nozzle technologies. Once a new and unfamiliar technology in the sheet metal fabrication industry, fiber lasers now are considered a proven and reliable approach to blanking operations. One benefit of using fiber lasers to perform blanking is the clean, oxide-free edge that you can obtain using a nitrogen assist gas with it. The absence of oxidation improves downstream processes such as powder coating and welding because better adhesion and weldability can be achieved. You can improve a fiber laser blanking’s cut edge by optimizing the assist gases and nozzle technologies. Nitrogen purity levels play a large role in edge and part quality. Understanding what to expect from purity levels can help you achieve the desired part quality and other end goals such as powder coat adhesion or weldability. If a bright silver finish is desired for industries such as medical and food-grade equipment, a purity rating would need to be 99.9 percent (see Figure 1). If the market you supply is agricultural implements and powder coat adhesion and parts per day are your main areas of focu...
