If your business does metal fabrication in Cleveland, you’ll need to weld many types of metals. Some materials are easier to weld than others. For example, you can weld carbon steel with many different techniques. However, when it comes to aluminum, TIG welding in Cleveland is the best method. Yet, even with the best welding equipment, it’s easy to make mistakes and end up with a lot of waste. Here are some of the most common mistakes you should consider avoiding.
Why TIG Welding?
TIG methods are easier to learn, and you don’t need to hold a welding rod as you weld. The filler feeds through the system as you weld, and it only takes one hand. This lets you weld accurately and safely.
Use the Right Alloy
Some aluminum alloys are not meant for welding. This is the reason most metal fabrication shops in MN don’t weld 7075 aluminum. Problems with cracking are commonplace. 2024 is another alloy most professionals do not like to weld. Extrusion Alloys like 6061 are sometimes welded with 4043 aluminum. The best alloys for welding are 3000, 4000, and 5000 series aluminum.
Use the Right Electrode Size for the Job
Electrodes get very hot while TIG welding and if they are too small you’ll have a hard time making a weld. If your electrode is too big, your arc wanders and makes welding difficult. This is why you need the right size electrode.
Proper Preparation
With metal fabrication in Cleveland, cleanliness is vital. The cleaner your surfaces are the better welding you can do. Not cleaning properly is a major reason for welding issues. Don’t use shop rags or compressed air or you’ll contaminate the weld. Rags may contain oils or dirt, and compressed air has moisture. Use only stainless steel brushes after you clean with solvents. If you brush first, you risk contamination.
