As an amateur welder and budding modern artist, welding one small item to another delicate or thin type of metal is a unique and fun art project. It's obviously going to be very important to minimize splash and to create the strongest possible hold between the two metals. In that instance, you are likely to find that drawn arc welding is going to be the most appropriate choice for doing so, especially if your art only needs to create that connection on one side of the larger, more delicate item. The information below will help you to understand why you will need specific equipment for your project.
Understanding Drawn Arc Welding
As with any form of welding, it is first necessary to be sure that the metal in question can safely and efficiently be heated to the appropriate temperature. Arc welding uses a DC power supply to do so. The drawn arc option works by placing the stud into the appropriate part of the welding gun. A disposable ceramic protectant known as a ferrule contains the molten metal that is required for welding.
The ferrule will be placed against the larger piece of metal and the DC power supply releases a signal to allow the welding gun to activate. Thus, the stud moves upward and the pilot arc is produced. Bookends would be a great welding project that you can make using drawn arc welding and then personalize by using different types and sizes of metal.
Controlling the Pilot Arc
The previously mentioned pilot arc is necessary because it establishes the area where the current will go. The lift mechanism will quickly lose its energy after the stud has connected to the molten metal and completed the arc. You may find that it is necessary to use a plunge dampener if the studs in question are particularly large.
That is due to the fact that they are effective at slowing the movement of the stud into the metal. By slowing the movement, splash will be minimized and the two metals are much more likely to connect at the right depth. As soon as the stud and the metal join, it should start to solidify almost instantly.
In conclusion, arc welding is an efficient way to connect a smaller, metal based item to one side of a larger, delicate item. Since arc welding varies from other types of welding because it can work on thin or delicate surfaces, it is a good idea to learn about the different equipment you will need for your artwork and the process of drawn arc welding, as listed above.
