The pros and cons of MIG Welding are usually established by the MIG welder type and the type of project. Prior to discussing the attributes of MIG welding, it’s necessary to first have a clear understanding of what type of MIG welder to utilize and what it is going to be used to achieve.
MIG welders come in a one-Phase, combination of one and three-Phase, and three-Phase. One-Phase MIG welders have a typical one hundred and fifteen or two hundred and thirty volts of alternating current and are utilized in home workshops/ garages, auto-body shops, ranches and farms, light maintenance work, overall repairs, artwork, and small fabrications.
The one & three-Phase MIG welders offer somewhat more adaptability for welding. Whereas they can achieve the same objectives as a one-Phase MIG welder, they can also be used for small fabrication and manufacturing.
Pros of MIG Welding
The following are the Pros of MIG Welding
Higher Productivity
A lot of welders are going to appreciate higher productivity because of time saved without the need to continually change rods or chipping away at slag, in addition to without the need to brush the weld continually. They’re able to weld faster and with less mess.
Easy to Learn
One of the top pros of MIG welding is its plainness. Welders can learn how to MIG weld in a couple of hours, and some instructors declare they can offer simplistic training in 20 minutes—with most of the time cleaning the weld.
Simple and Great Welds
MIG provides improved weld pool visibility. Add this to the basicness of the process and better management provided by the automatic-feed wire, and MIG is going to make it easy to produce a great appearing weld.
Clean and Efficient
Because MIG utilizes a shielding gas for protecting the arc, there is a minimal loss of alloying materials as the metal transfers over the arc. There isn’t any slag to remove, which is run of the mill for stick welding, and only minute weld spatter is created. Following a short clean up, MIG welders are going be back on the job in no time thanks to the decreased clean-up needed.
Versatile
MIG welding is very flexible and can weld a wide variety of alloys and metals, while operating in different ways, like semi and fully auto. Whereas MIG welding is beneficial for a lot of DIY welding jobs, it is also utilized by a large number of sectors. MIG is used for these metals: stainless steel, magnesium, aluminum, copper, mild steel, nickel, and a lot of their alloys, in addition to iron and a lot of its alloys.
Quicker Welding Speeds
The continuously fed wire keeps each hand free for MIG welding, which increases welding speeds, weld quality, and general control.
Cons of MIG Welding
The following are the Cons of MIG Welding
Cost
Welders are going ascertain straight away that MIG welding equipment is more complicated and expensive, while additionally giving up portability. Moreover, shielding gas, electrodes, and replacement nozzles and tips for MIG welding can accumulate.
Restricted Positions
The fluidness of the welding puddle and the increased heat input of a MIG welder x’s it out for up and down or for welding overhead. Whereas some welders wouldn’t even consider welding in one of those positions, take this aspect into consideration when choosing whether or not to purchase a MIG welder to be sure it can achieve all of the projects planned for it.
Inapplicable for Outdoor Welding
In addition to not being able to move from place to place, MIG welders are also Inapplicable for welding outdoors because they utilize a shielding gas to safeguard the weld’s purity. Wind is going to wreak havoc with the shielding gas and affect the weld quality. A MIG welder also cannot be taken into a field to repair farm equipment but works perfectly in the garage for small fabrication projects or automotive work.
Fast Cooling Rates
The welded metal s going to cool at rates that are higher because they are not covered by slag when the weld is finished.
Unsuitable for Thicker Metals
Whereas MIG welding is fine for thinner metals, it doesn’t provide adequate penetration for thicker steel that requires a more solid weld.
Shielding Gas
The shielding gas bottle could take time to replace and could get in the way when welding.
Metal Preparation Time
Prior to welding with a MIG welder, the material has to be free from rust or debris in order to get a good weld and for the sake of safety. Because they are relatively small and placed somewhat high above the level of the flooring.
