Aluminium is one of the most commonly used metals in building, construction and tool fabrication. A common misconception is that aluminium is very difficult to weld. However, the truth is that aluminium is just as easy to work with as steel. For the best results in joining aluminium, there are certain welding rules which you have to follow. Here are some tips that you should follow when working with the metal.

Safety First

You should weld aluminium in an open area or a place which is well-ventilated. The welding process leads to the production of very hazardous fumes, and protecting yourself will help you avoid the effects of the fumes. Have a welding mask to protect your face, especially the eyes, from the sparks. Cloves and leather clothing will protect your hands and body from the molten metal splatters while leather shoes will protect your feet from dripping hot metal. Finally, use a respirator to protect you from fumes if you will be welding for a long time. 

Clean out the Metal

Another common mistake people make when welding is failing to clean all impurities off the metal before starting the welding process. There isn't a requirement which says that the repair area must be perfectly clean, but at least brushing off the dirt with a wire brush will remove the dirt. When the impurities are left on the metal, they are absorbed and retained in the final product, which is unsightly.

 Decide on the Best Welding Method

There are several ways that you can weld your aluminium. The most common are arc welding, gas metal arc and gas tungsten arc welding. Arc welding is the oldest and most common way to join aluminium. Here, you simply use a power supply to create an electric arc, which melts the metal. The method works with both DC and AC power sources and does not need a lot of equipment. The problem with this method is the amount of training it needs to master, and the fact that it does not work well with thin metals. MIG welding and TIG are newer and simpler. They are more precise and can be used for thin metals, especially TIG welding.

Other crucial things to remember include the fact that hydrogen is your worst enemy when welding, and if you are using MIG welding, the gas you choose will determine the quality of the product. You can have an expert handle the welding process for you in case you are not confident about your welding skills. Contact a provider of welding services in order to learn more.

Hey, there! My name is Mandy and this is my manufacturing blog. The articles that I write and post here will help you to gain a better understanding of the world of manufacturing. My husband works at the local manufacturing plant and he invited me along to a recent bring your family to work day. It was really exciting to see my husband's workplace and it inspired me to find out as much as I can about his job and the industrial sector. Over the past couple for months, I have learnt so much cool stuff that I just knew I had to start this blog.
