One of the best things about steel ERW tube is you can effectively cut it to different lengths. It offers more opportunities and can save costs, time, and resources. However, you need to be careful about which methods you use. Using a plasma cutter can offer some advantages, but has drawbacks too. We want to have a look here, so read on to learn more.
Advantages
If you compare different cutting methods, you can see the various benefits of each of them. Plasma cutting is a versatile option, suitable for a wide range of materials (as long as they are conductive). It can work cut thick materials with precision. Plus, it provides good edge quality in most cases.
Overall, plasma cutters can be a cost effective option suitable for various cutting needs. Crucially, they can be a smaller investment than laser cutters. They are efficient and generally cheap to maintain too.
Things to consider
While there are lots of benefits, it is important to also consider the drawbacks with plasma cutting. This can help you to determine if it is right for you. You need to be especially careful when you are dealing with tubing, including steel ERW tube. The cutter can spray dross on the inside diameter of the tubes. Therefore, it is important to address it or the ID can be rough and dirty. Keep in mind that there will be more dross with thicker walls.
It’s also important to think about the fumes the plasma cutter can generate. The risk is higher here if you are cutting galvanised steel. This can produce zinc oxide fumes, potentially causing metal fume fever and lung irritation. High or long term exposure can damage the respiratory system. It’s vital to have effective ventilation and make sure workers wear PPE.
Another thing you need to consider is the kerf (cutting width). When you use a plasma cutter for thicker materials, including ERW tube, it increases the width of the cut. If you aren’t careful, it can mean lengths are not accurate. In addition, it also means more material waste and fume generation.
Finally, you need to look at the cutting speed. Plasma cutters are fast in the majority of cases. However, they will slow down dramatically as you increase the material’s thickness. There is a point you can’t go past as the speed will hit the floor.
