Other reasons why you need to use shielding gases when welding includes the need to: Check out this article on for more info. If the weld pool reacts with these elements, it will become subject to failure from porosity. Shielding gas is of utmost importance in Metal Inert Gas (MIG) Welding in order to keep the molten weld pool from oxygen, nitrogen and hydrogen in the atmosphere. Flux Core Welding Can Easily Be Done Outdoors Learning flux core welding will provide you with the opportunity to weld a variety of materials both indoors and outdoors. There are several advantages to using flux core welding over other welding types, such as MIG welding. Fortunately, there are ways to mitigate these complaints that will be discussed in further detail below. One of the few downsides to this technology is the effort it takes to clean up the slag that is a by-product of the welding process. This is because MIG welding is known for being nearly impossible to weld galvanized steel with because of issues with porosity. Since a shielding gas is not needed, you can also use this method to weld in just about any type of weather.Īs will also be discussed in further detail later, this welder is also one of the best systems for welding galvanized steel. These machines can plug into the standard 120V power system in your home. They are also easy and straight-forward to operate when compared to stick welding. The Flux-cored welder is the field worker’s best friend because they are easy to move from site to site. Here’s a cool video demonstrating the basics, then we’ll get into the nitty gritty.įlux Core Welding, often abbreviated as FCAW, involves the use of a welding wire that is similar in many ways to Metal Inert Gas (MIG) welding except for the fact it includes a flux-cored compound within the wire that has the capability to remove the need for shielding gas.Īs for the question of whether this welding method is any good, the answer is yes, provided that the weld bead is being laid down in the recommended circumstances, usually on thicker metals as will be discussed later in this article. I will also compare flux core welding to both TIG welding and MIG welding and answer the question of whether flux core welding is better than these welding methods. I have also included sections on which wire electrodes are the best for stainless steel, galvanized steel and general repairs. Here you will find a guide to what makes flux core welding so popular. The cons of flux core welding include the cost of the electrodes, the appearance of the weld bead, spatter, and slag inclusions to name a couple. Several pros to flux core welding include portability, ease of use, versatility, usability outdoors, and the ability to weld through rust. So what are the pros and cons of flux core welding? This guide should also help you decide whether flux core welding is right for you, how to get started, and what to expect when starting up. I wrote this guide describing in full detail the pros and cons of flux core welding.
