The MIG weld process is a popular method of welding stainless steel. The MIG process is a proven method of joining metal and has been used for decades in the aerospace industry. The process is very easy to learn and will allow you to get your projects welded quickly. The MIG process can be used on most types of stainless steel wire, plate and rods. The MIG process will allow you to create your projects faster and easier than any other method.
Welding stainless steel is notorious for its poor weldability. However, if you have the proper knowledge on how to successfully weld stainless steel it will be a completely different story. When welding stainless steel the MIG process is one of the best ways to go.
Stainless steel is one of the hardest metals to weld and there are a lot of reasons why. The main reason for it’s hard to weld nature is that stainless steel has a very high melting point. This high melting point keeps it from being easily welded.
That being the case, if you can’t MIG weld stainless steel then you probably aren’t going to be able to MIG weld any other type of metal. This higher melting point also makes it difficult to weld stainless steel if it is being made into a multi-piece assembly.
The MIG process is more effective than any other welding method when welding stainless steel. By correctly using the MIG process you will be able to weld stainless steel with no problems. The MIG process will allow you to weld parts together quickly and easily as long as you have the proper equipment and know how.
The MIG process works by combining an electric arc with a high voltage. The high voltage is used to melt the metal and then the electric arc is used to weld the melted metal together. The MIG process can be used on a wide variety of metals and in most cases it will weld stainless steel if done properly. Below are the rules for successfully welding stainless steel using the MIG process:
The metal must be free of contaminants
The MIG process works best when the metal being welded is free of any contaminants. The contaminants will weaken the weld and will make it very difficult to get a good weld. All stainless steel wire, rods, and plates need to be free of any foreign matter. If there is a contaminant in your project then you will end up with a poor weld that will break easily or fail over time.
The contaminants that you need to stay away from are dirt, grease, flux residue, and rust. These contaminants will cause damage to the weld and will weaken it. You also need to make sure that you don’t have any dirt or grease on the metal before you weld it. If you do then you will have a very difficult time getting a good weld because the contaminants will weaken the weld.
The metal must be clean and free of oxide contamination
To get a good weld on stainless steel you need to make sure that the metal being welded is clean and free of oxide contamination. Oxide contamination can be caused by creating an oxide film on the metal while it is being stored or made. This oxide film will make it very difficult for the MIG weld to melt the metal. If you are trying to weld stainless steel and you have oxide contamination then there is a good chance that you won’t be able to weld it successfully.
The oxide will also make it difficult to weld on stainless steel that has been previously coated with other metal alloys. The oxide film will make it almost impossible for the MIG process to melt the metal and this could cause you problems when welding on stainless steel that has been previously coated with another metal.
Let’s take a look at how you can successfully weld stainless steel using the MIG process
Step 1: Clean the Metal Surface
You need to have a clean metal surface to weld with. If the metal being welded is dirty then it will make it difficult for the MIG process to work. The dirty metal will cause all types of problems for you during the welding process.
Step 2: Remove Excess Flux Residue
If there are any flux residues on your metal surface then you need to remove them before you begin welding. The flux residue can cause corrosion on the metal and weaken the weld. This weak weld will then break over time, thus causing a failure in the project. You need to make sure that there are no excess flux residue left on your metal surface before you start welding.
Step 3: Level the Metal Surface Before Welding
In order to get a good weld on your metal you need to make sure that the metal is level before you begin welding. If the metal isn’t level then you will get a very poor weld that will crack and fail.
Step 4: Choose the Proper Wire Size and Style for Welding Stainless Steel
You need to make sure that the wire you are using is of the proper size and style for your stage of welding. If the wire is too small then it will be very difficult to get a good bead weld. If the wire is too large then you will have a hard time getting a good weld. You want to choose the correct wire size for your stage of welding.
The size of the wire used in your MIG process can make a huge difference in how well you get your welds done. For example, if you are using a very small sized wire then you will be able to get a good bead weld on your metal but it won’t be very strong or durable. If you are using a very large wire then you will have a very difficult time getting a good bead weld.
Step 5: Test for Proper Voltage and Amperage
In order for the MIG process to work you need to make sure that you are using the proper voltage and amperage. The wrong voltage or amperage will cause your MIG process to not work. There is no way around it, if you are using the wrong voltage and/or amperage then you will not be able to MIG weld stainless steel successfully.
Step 6: Apply the Voltage and MIG Weld the Metal
You are now ready to apply your voltage and MIG weld the metal. Make sure you are using the proper voltage for your stage of welding. You will also want to make sure that you have your amperage set properly. If you don’t have your amperage set properly then you will not be able to get a good weld on your metal.
Step 7: Apply Heat to Your Welded Joints
With your welded metal joints you need to apply heat to them in order to make sure that the weld remains strong and durable. The metal will eventually cool down and this will cause the weld to become weak or break over time. You want to make sure that you apply enough heat during your MIG process so that the metal is heated properly. If you don’t then your weld won’t be strong or durable.
Step 8: Inspect Your Weld for Proper Durability
Inspect the weld to make sure that it is strong and durable. If there are any defects in the weld then you will need to make repairs before you can use the metals for any projects. If there are no defects then you can use the metals for your projects.
