![]() ![]() This is because iron (mild steel) or brass bristles might damage the weld by creating chinks and thus generating structural problems. ![]() Something to not underestimate when using the MMA process with stainless steel is the acquirement of a welding brush with stainless steel bristles. There are several coated electrodes on the market, each coming in different thicknesses to meet any possible need. Should you need to perform a second filling phase, you must carefully remove the slag by using a welding hammer and deeply clean it with a welding brush, in order to avoid slag contaminations of the seam. This type of welding is widely used in professional settings, often in worksites or other outdoor places.Ī “flaw” of this welding process is the small yield, which means that you might need to replace more than one electrode to complete a single welding seam. Since it does not require a gas protection, the coated-electrode welding process can be easily handled and it allows the operator to work in places that are difficult to reach. The slag, besides protecting the hot seam, releases alloy and deoxidizing elements into the weld pool. The MMA welding, unlike the MIG-MAG and TIG processes, does not need the protection gas during the fusion, the burning coating generates an instantaneous coverage and produces a solid protection called slag. ![]() With just a few more euros, you can also purchase a welding hammer and a welding brush to easily remove the slag from the welds. The coated-electrode process, also known as MMA process, is the most common one among the typical welding methods it is very appreciated in the DIY field thanks to the low prices of its generator and coated electrodes. ![]()
