Welding is usually the process of joining two metals by applying heat on them and it is used in auto repairs, homes, craft projects and boats. Every metal type has a significantly different method of joining it to other metals. Below are some important steps to follow during stainless steel welding.
The first step would be to ensure your own personal safety before embarking on this exercise. Make sure that you wear some protective clothing like full-length pants and shirts that expose as little skin as possible. You can also invest in a pair of gloves, protective eyewear and ear protection.
There are various joining methods that you ought to choose for the base metals. The most common of these joining methods are the edge, T, lap, butt and corner. In order to choose the best method, you should consider the thickness of the metal you wish to weld, the strength required for the job and the joint accessibility.
The welding process that would be most appropriate for you to use ought to be considered. You can choose from the following processes gas tungsten arc or GTAW, shielded metal arc, SMAW, gas metal arc, GMAW, flux cored arc, FCAW. You could also look at getting an inert gas that would be compatible to the process you choose from these except for the SMAW, for the others you will choose from argon to helium.
You will also need to get filler metal in case you will be joining two metals that are the same. You should make sure that the base metal you end up with would emulate the composition of the base metals. If the metals to be joined are not similar, then you ought to ensure that you choose a filler metal that would have the least cracking chances and it also ought to be compatible with the base metal.
After that you should ensure that you clean your base metal to eliminate the chance of oxides forming on your base metal. You should use a brush made of stainless steel wire to gently brush the base metal to remove any burrs and existing oxides. Ensure you also wear protective gloves to ensure that you do not transfer any oils that could be on your hands onto the stainless steel.
The next thing to do would be to ensure that you bring the metal you will be using to room temperature. You should note that this is done on martensitic and ferritic metal only but for the austenic metal you will not need to preheat it. It would also be appropriate to preheat your metal if it is thick or even high in carbon.
Lastly, you should apply the welding torch to the two pieces of metal you would be welding together. You should also see to it that you also apply some post heating after the process as this metal cools down rapidly causing lots of internal stress which could lead to cracking. The post-heating process is therefore essential to eliminate chances of cracking and especially more so when thick metal pieces are joined together. Ensure that you remove any slag that is left on the weld spot.
