When two metals are joined together through the application of heat then the process of welding is said to be completed and can be used at homes, auto repairs, boats and craft projects. It is slightly different for every type of metal. Below are some important tips on how to carry out stainless steel welding.
Ensuring that your safety is guaranteed should be the first thing you do before attempting to start on any work. You should ensure that you get protective clothing like shirts and pants that ought to be full-length and exposing only some little skin. It is also advisable to have on some protective ear and eye protection and also gloves.
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.
You should also consider the appropriate process of welding your stainless steel in completing your project. There are several processes that you can use like shielded metal arc or SMAW, Gas tungsten arc or GTAW, Flux cored arc or FCAW and Gas metal arc or GMAW. It would also be important to get an inert shielding gas that is compatible to the process you have chosen above except for SMAW, others use argon to helium.
This process will also necessitate you to choose filler metal if you will be joining two similar metals. Ensure that your base metal will mirror the base metal composition. If the metals will differ, ensure the filler metal you settle for will have the least chance of cracking and should also be compatible to your base metal.
The base metal should then be cleaned well in order to eliminate the chances of the formation of oxide on your base metal. A brush made from stainless wire would be efficient for this job of gently brushing the metal to completely eradicate oxides and burrs that exist on it. Ensure that you also put on your gloves to prevent oils from your hands from being spread to the stainless steel.
The next step would be to bring the metal to the room temperature. This would not be necessary if you will be using austenic metal but for ferritic and martensitic metals, you should preheat. You should also preheat the metal if it is particularly high or thick in carbon.
Finally you should use the welding torch on the two metal pieces you would be joining together. As this particular metal cools in a rapid way, ensure that you apply post heating to deal with the internal stress that is as a result of the rapid cooling down to prevent it from cracking. This is especially important when thick metal pieces have to be joined together. Make sure that any form of slag is removed from the spot that was welded.
