There are various things to consider when choosing ER70S-6 MIG Welding Wire. For example, you’ll need to know whether the wire suits the type of metal you plan to weld and its gas flow rate. You’ll also want to look at stick-out strength and the wire’s durability.
About ER70S-6 MIG Welding Wire
ER70S-6 is the most popular type of MIG welding wire. It has high silicon and manganese contents and is used for various applications. This type of wire is available in a variety of arc characteristics. It has a rutile coating that gives reasonable weld puddle control. Also, it has a higher silicon content than ER70S-2. This content increases the fluidity of the weld pool. This process makes it more suitable for GMAW and GTAW. Also, it is more compatible with high percentages of argon. It is commonly used in automotive, general fabrication, and pipe welding.
MIG Welding Wire vs. FCAW Welding Wire
MIG welding and FCAW (Flux-cored arc welding) are similar in many ways. They use a compressed gas tank and a wire spool to perform the welding process. However, the benefits and drawbacks of each type differ. Both types are used to weld metals; each has advantages and disadvantages.
MIG welding is known for its speed and minimal spatter. But the results can be compromised by improper technique. Whether you choose MIG or FCAW, the process is relatively easy to learn. You will only need a few pieces of equipment and a bit of time to get the hang of it. And once you’ve mastered the process, you can move on to more complicated jobs. MIG welding is more tolerant, but you’ll still need to choose the suitable wire. The wrong wire can cause weld cracks and other problems. The most important thing is to feed the wire into your welder consistently.
Characteristics of ER70S-6 MIG Welding Wire
If you are a beginner and unsure of the characteristics of ER70S-6 MIG Welding Wire, you need to know a few things. This wire is excellent for welding steel with moderate rust and scale. It is also used in MAG and TIG welding. This wire has a higher silicon content, which improves the flow of the weld pool and produces a smoother bead.
Compared to ER70S-3, ER70S-6 has a high manganese and silicon content, which results in a better weld. This wire is suitable for mild steel and aluminum and can be used in various applications. The higher levels of deoxidizers make this wire useful for welding dirty or rusty metal.
This wire is available in a wide variety of spool sizes. Typically, you can find this type in a 44-pound spool. However, you can also find a 1,000-pound drum. It is an excellent option for welding carbon steel. It is used in both manual and automated applications.
Welding Precautions
Choosing the correct gas flow rate for ER70S-6 MIG welding wire is a personal choice. However, there are guidelines to help you find the best fit. When welding stainless steel, the amount of gas needed differs from that of aluminum. This amount is because of a variety of factors. Among them are the type of metal, the thickness, the wire feed speed, and the electrical settings. Ideally, your MIG welder should use a gas pressure between 20 and 25 CFH.
If your MIG welder has an orifice valve, it automatically adjusts the pressure drop to keep a consistent MIG gas flow. This process can save you over $1000 a year per welder and improve your weld starts. Choosing an orifice valve designed explicitly for your gas tank is crucial. When a higher gas flow rate is used, it can create turbulence. This turbulence can lead to brittle welds. To avoid this, try using a gas pressure of no more than 15 CFH. If you work in a low draft environment, you can work with a higher gas flow rate.
Uses of ER70S-6 MIG Welding Wire
ER70S-6 MIG welding wire is used for a wide range of applications. It is designed to weld metals such as steel and stainless steel, as well as sheet metal and pipes. Also, it can be used with both argon and CO2 shielding gases. It is also suitable for welding on dirty or scaled surfaces. This type of wire is used in single and multiple-pass welding processes.
