![]() Any kind of breeze can disrupt your ability to MIG weld effectively. MIG welding outside is difficult because it requires a shielding gas. This increased manufacturing cost is passed on to the user, making MIG equipment costly compared to stick welding equipment. MIG equipment, particularly the machine, is quite a bit more complex than what you use for stick welding and it costs more to manufacture. One of the main limitations of MIG welding is its cost. Here are some of the key limitations of MIG welding: 1. MIG welding is not without its limitations. The width of the MIG weld pool is determined by the speed of travel (how fast you’re welding), this allows you to make better control over the width of the weld. With MIG welding, you can deposit more metal with each pass, which means you can get away with fewer passes when working on a big joint. These longer passes are another reason that MIG is faster than other welding processes. MIG welding also allows for larger passes with a single weld. But with MIG welding, you can use the whole electrode, this eliminates the wastage of electrode and reduces the cost. With stick welding, the last few inches of an electrode cannot be used. Eliminates Stub LossĪnother advantage of MIG welding is that it eliminates electrode stub loss. It may not seem like a lot, but when you think about how much time you can lose stopping and starting over the course of a project (or a career!), it can really add up. With a continuously fed electrode, it helps to limit the number of times that you have to stop welding, adjust or get a new electrode, and then start welding again. MIG welding also cuts down on the number of starts and stops. This means that less time is spent on post-weld cleaning, saving you time and money. Unlike stick welding, MIG welding doesn’t involve flux or create much slag (debris). ![]() MIG welding also eliminates almost all need for cleanup time. The amount of current you use determines the penetration you can achieve with MIG welding. MIG allows you to achieve good penetration (weld depth) and still produce a smooth, strong weld bead. MIG welding also works on metals in a wide range of thicknesses. Several of the processes that take place during a MIG weld are automated, which makes it easier to pick up and succeed with quickly than other types of welding such as TIG welding. Ease of UseĪnother advantage of MIG welding is its ease of use. This makes MIG welding an ideal choice for large-scale projects or tight deadlines. With a continuously fed electrode, MIG welding can outpace other welding processes under identical conditions. One of the main advantages of MIG welding is its speed. Here are few of the advantages that MIG welding offers: 1. Useful: Robotic MIG welding is also possible, which completely automates the welding process. MIG welding machines can use different types of metal transfer, such as short circuit, spray arc, pulse, and globular transfer, depending on the type of metal and the desired outcome of the weld. ![]() The gun also directs a shielding gas flow (usually argon) over the weld pool. The gun then melts the electrode and deposits it on the parent metal to make a weld. The electrode wire is fed into a MIG welding machine, which directs it down into a gun. MIG welding, also known as Gas Metal Arc Welding (GMAW), is a type of welding that uses a continuously fed supply of electrode wire and a shielding gas to protect the weld pool from the atmosphere.
