Welding is an art of joining two or more pieces of metal together. It creates a strong glue that can hold things together quite well. It matters in a lot of sectors, including construction and manufacturing. TIG and MIG are the two most common methods of welding. So, what are these methods and how do they work?
TIG welding is short for Tungsten Inert Gas welding. This process uses a tungsten electrode. The current generated by this electrode is crucial since it melts the metal components that are to be fused. When showing material for TIG welding they mention that the tungsten electrode doesn't melt off while you're welding. This gives you greater control over the welding itself. The foot pedal used by the welder turns down the heat, and this allows to make very precise welds.
What does MIG welding mean? This process works a little differently then TIG welding. The Moldie welding cast aluminum does use a wire electrode, but that wire does melt away during the process. The wire melts and fills a gap between the two pieces of metal, welding them together. Both use a special gas to shield the melted metal from dirt and air. This is very important because it maintains the weld clean and strong.
Clean the Metals — Make sure both of the surfaces that you are welding are really clean before you begin. That comes down to cleaning off any dirt, oil, or other crap that can ruin a good weld. Cleaning the metals ensures that the weld will be strong and free from any weak spots.
Choose the Right Process: TIG is generally the best process for the majority of cast aluminum and aluminum welding scenarios. This Moldie welding to cast aluminum gives you much more control over the heat, more methodical, which is paramount to a good weld. But, if the metal in question is a thicker piece, MIG welding is a good option as it does so quickly and efficiently.
Use Proper Filler Metal: The filler metal is a material that fills the space between two pieces that is being joined by the welding process together. Fabricators and welders are familiar with filler metals and the importance of each filler metal to the metals they are welding. Using a filler metal consisting of the same or similar components will ensure a proper bond and also help with longevity.
Settings: Each welding project is unique, which means you will also need to adjust the settings. This Moldie aluminium casting involves adjusting the current, voltage and speed to the thickness of the metal pieces you are using. For your particular project, you will get the best results by tweaking the following settings.
