ine welding wire

Welding is a term used to describe the method of joining two pieces of metal. MIG welding is the name for Metal Inert Gas Welding; it is used to melt two pieces of metal together along with filler wire. This method is used to create a strong joint as the metals cool together. Using MIG welding, you can join almost all types of metals but the strength of the joint depends on the wire used for welding. The most commonly used metals for MIG welding are stainless steel, carbon steel, and aluminum.

MIG welding is used widely in the construction and building industry and it helps in building structures such as planes, high rise buildings, and bridges. This welding has played an important role in most of the amazing and mind-blowing skyscrapers around the world. In this post, we’ll help you choose the best MIG welding wire for your business.

Buying Guide: How to Choose The Best Welding Wire for The job:

Choosing the correct type of MIG welding wire is important for the strength and the look of the welds you want to create. As explained earlier, the common metals used for MIG welding are stainless steel, carbon steel, and aluminum. Each of these metals has different properties and have their pros and cons. Following are some factors to consider before choosing a MIG wire for welding:

Size:

Size (as always) plays an important role in the performance of MIG wire. By size, we mean the diameter of the wire and the spool size. To get the right MIG wire size, you must first go through your MIG welder’s instructions where it is stated about the electrode it is rated for. It is important to go for the rated electrode otherwise you’ll end up having a too small or too large wire. You also need to take into account how thick materials you are going to weld.  (For more detailed guide check out This guide!)

A too-large wire can cause feeding problems and it ruins the feeder line. MIG wire is measured in pounds instead of length, and thus you’ll have to pay more attention to the spool size and to the size your machine can fit.

Right wire metal:

The MIG wire’s metal should be the same as the metal to be welded. If you’re going to weld stainless steel, you should use stainless steel wire and aluminum wire should be used for welding aluminum metal. Steel wires are sometimes coated in copper so that oxidation is prevented. Some great MIG wires even use other elements along with the primary metals such as manganese, titanium, and silicon which help in deoxidizing the weld and make it less porous and more stable.

You should always consider the wire’s primary metal when you choose the wire. If you’re unsure, you must discuss with the local welding supply shop or the salesperson. Lincoln and INE welding wire companies are known to provide good customer service.

Wire thickness:

The second important factor in selecting the wire electrode is its thickness. The diameter of the wire is actually determined by combining the thickness of the base metals that are being welded together. There are many manufacturers that include a thickness chart in the package too, I would suggest that you check that out, but in most cases, for hobby users the .030 wires are great.

Consistency:

One thing you should remember is that all filler electrodes aren’t manufactured equally. Always look for a wire that offers consistent feed ability, chemistry, wire diameter, and arc performance. If there are variations in the wire, it may result in high operating cost, lower productivity, and inconsistent welds. Inconsistent wire diameters can cause feeding issues and as a result, you’ll have to do repetitive procedural adjustments between the spools or within a spool. (be aware, do not use the cheap wires produced in China)

Gas vs. Flux Core Wire:

Before choosing a MIG welding wire, you have to decide between a gas or gasless wire (if you are interested, here’s guide how to pick the right gas for the job). Flux core wires have an internal coating that allows you to run without the shielding gas mixture. If you have an enclosed shop or area, this is not a good option as it leaves slag and produces toxic fumes too. Flux core wires are more helpful in outdoor areas. A regular MIG wire requires you to use a shielding gas along with the welder. It offers slag free and clean welds in indoor settings but is not suitable for inclement conditions.

Gas shielded arc welding wires are further divided into three categories; Solid gas metal arc welding wire (GMAW), Composite GMAW (metal-cored) wire, and Gas-shielded flux-cored arc welding (FCAW) wire. GMAW requires a composite metal-cored electrode or a solid wire electrode. Metal-cored wires are tubular electrodes and they have metallic constituents in the core. Metal-cored wires produce a slagless weld just like solid GMAW wire and it requires no cleanup. Gas-shielded FCAW wire is tubular electrodes that contain fluxing agents in the core along with deoxidizers to give protection from the atmosphere.

FAQ Section:

What are the prices of the welding wire?

The prices of the welding wires depend on the brands, spool size and types of wire. Some of the brands are quite expensive while others are cheap. MIG welding wires are not that expensive and you can get a good one within $25 to $40.

What are the perfect diameters and sizes?

The perfect size that can be used for most jobs should be at least 0.030 inches. If there are thicker items that you need to weld, you should go for 0.035 inches of thickness.

How durable are the welding wires?

Welding wires of good brands are quite long-lasting and durable. If you take good care of them, you do not need to worry about ruining it. (storing it in right conditions)

How many types of wires are there?

The wires are divided into two categories; flux core wire and gas shield wire. Flux core wire prevents weld contamination and is good for outdoor tasks when it is windy. Gas shield wire is good for working indoors. Gas shield wires provide amazing protection against contamination and give smoother finish with less time spent on post-treatment.

Conclusion:

A good welding wire needs to be changed according to the base metal you’re working and the type of environment you are working in. It is very important to choose the correct type of wire so that you can get the best results with minimal effort put in. If you want to choose the perfect MIG wire, you must consider the durability, check the size, and prefer the versatile goods. To maximize the lifespan of the welding wires you store it in a safe place and dry place. As always it is good to follow the instructions and the manual to get the best results.
