Welding involves situations that require extreme heat and the electrodes play a very important role in such situations. Well, there are different types of welding electrodes available in the market and professionals have reasons to choose anyone. Some of the well known types of electrodes are metal core, solid core and flux core. Though the availability of all these types has increased manifold, the flux core arc welding coupled with the gas metal arc welding are the professionals’ favorites for steel. Basically, different types of steel require different types of electrodes to ensure optimum outcome.
Therefore, when someone is choosing the electrode, he or she must consider the type of steel to be welded for the purpose. In this regard, one must consider the mechanical properties, chemical compositions, as well as the microstructure of the steel. The methods of processing the steel also play an important role in choosing the electrode. Now, it is easy to understand why choosing the ideal electrode should be left to the professionals.
Even if you have managed to choose the somewhat right electrode for welding, there are some other and even more complicated challenges lying ahead. Basically, you need two equipments required for welding – the electrode and metal for welding. You have to make sure that both of them are complementing the base metal that you are welding. At the same time, the electrode must not offer the exact chemical composition metal match as it may cause rust erosion. Ideally, you should be using an electrode that will have around .02 to .04 percent less carbon than the metal to be welded. However, make sure that you are using suitable metals to compensate this lack of carbon count by choosing appropriate alloy.
Remember, it is very important that the electrode you are using is capable of giving sufficient tensile strength and impact resistance to the metal. In this regard, overmatching is very important. Make sure you are not using additional metal to overmatch as that may give more strength to the deposited metal than the weld metal.
If you are trying to do it yourself, you need to do some study on electrode. Go for the AWS guide to size and numbering system. This is very important in understanding the proper application of the electrodes. However, the good thing is that the electrodes have clear labels and codes so that you can go through them easily. Anyways, it is best to hire professional welding services to ensure that you get the optimum result with welding.
