These days all over social media sites you’re seeing colored welds. Welders are displaying their art pieces in contest and or just to show off their skills. Accumulating beautiful colors is actually pretty impressive but is it a good thing? Having multiple colors doesn’t mean it makes it a great weld; it can actually be the exact opposite. The color in a weld is actually a sign of oxide. If you didn’t know already, oxide decreases the ability of stainless metal to resist corrosion. Corrosion degrades the quality of the weld. Therefore when welding on a job you should always do your best to weld shiny chrome colors instead of multiple colors.
Anyway, we can lend you some guidance on how to achieve those awesome colors. First of all, it’s best to use a gas lens instead of using a collet body. Using the gas lens will help you get a smooth column of shielding gas which will lead to the best outcome. To obtain a fine control and a perfect bead is to use the pulse setting on your machine. When using the pulse setting it allows you to lessen the heat and get a deeper puncture. The result in getting the different types of color for that type of metal is created by the temperature and how long the high temperatures are being held on the metal. Below is a chart of temperatures and corresponding colors:
Now we understand that colored welds are fun to look at and achieve but are not all the best welds! If you haven’t attempted to create beautiful colored welds get out there and try it! Put your welding skills to the test and see what you can come up with!
