There are just a few aspects that welders should consider. With this blog post, they will learn about the basics of welding stainless steel. Read more here. Selecting the process for welding stainless steel will depend on the finish of the material used and thickness of the metal. Although there are several methods for welding stainless steel, most welders only used these three techniques.
These are as follows:. This method is ideal when welding critical joints. It is also widely used in industries where fine and precise welds are required.
Generally, this method uses argon gas that is mixed with helium, hydrogen and nitrogen. Argon gas is used since it protects and cools down the tungsten. Aside from that, it prevents oxidation. Lesser smoke is also released by argon gas compared to other gases. As the name suggests, this is the welding process for spot or seam welding.
Spot welding is known to be the most economical technique of welding. Moreover, the equipment used for resistance welding is very versatile.
Hence, it is perfect to use for small and large welding projects. Resistance welding uses an electrical current to melt metal edges and bond them together. This technique is known to be a productive choice for metals with a low melting point.
This is because it can be easily modified to prevent metal distortion. This method is a semi-automatic welding process that provides durable bonding of two pieces of stainless steel especially when it is done correctly. MIG welding allows the welder to utilise a pulsed current supply. In this way, it will be easier to weld the hard-to-reach corners on those intricate stainless steel projects. Welding stainless steel specifically using MIG method requires particular tools and materials to finish the task.
In MIG welding , a continuously-fed electrode wire melts into the weld, enabling two dissimilar metals to be joined without heating them to their melting points. A filler must be used since the melting points of the two dissimilar metals may be very different. For instance, if one of the metals is overheated to reach the melting point of the other one, stress cracks and microfractures may result. Welding two dissimilar metals is possible, but a very difficult process with plenty of complications.
To boil it down, welding dissimilar metals together is difficult to do right, and often produces inferior results to using metal alloys that are similar or the same. By taking into account the long-term effects of using different metal alloys in a custom wire form, you can make sure that you get the right basket for the job.

How to Weld Stainless Steel to Other Metals When welding stainless steel to other metals, other types of welding should be considered than resistance welding.
Combining dissimilar metals together, such as welding stainless steel to carbon steel, adds extra challenges to the process. To prevent oxidation and increase resistance to corrosion, a single-sided welding process can be used creating inert backing gas protection between the interior and exterior welds. The resistance welding RW equipment is incredibly versatile, which means it can be used on both small and large projects.
RW uses an electrical current to heat frayed metal edges and seal them together. This type of welding is exceptionally productive on metal with a low melting point because it can be tailored to prevent distortion of the metal.
MIG welding is a semi-automatic process that when done correctly offers a strong joining of two pieces of stainless steel.
You can prevent this rusting by coating the welding wire. Currently, the market is flooded by many stainless-steel products. Some are legit, while others are counterfeit. Rogue producers use a coating to replicate the appearance of real stainless steel. As a welding professional, you can pass over an ordinary magnet to determine whether your product is authentic. Genuine stainless steel is a low magnetic conductor. A spool gun keeps the welding wire in the welding machine. It also helps the welder switch out the stainless wire to the spool.
This action saves time during welding. Before you begin working on your machine, ensure you load the spool gun correctly. Back purge is necessary to prevent contaminating the weld with impurities. You can back purge by fitting a hose pipe with a T junction.
Ensure you fasten the hose pipe with tin foil for more reinforcement. This procedure needs to be done on the inside of the tubing to fill them with welding gas. Knowing how to MIG weld stainless steel should be an essential skill in your welding career. Stainless steel is a sensitive material and also among the most widely used items in the market.
The details shared above will guide you in your mission of welding stainless steel using the MIG process.
