Choosing the right tool is crucial, considering that grinding weld seams constitutes up to one-third of the tasks performed by welders and fitters.
To prevent overheating and metal melting onto the abrasive, use caution when working with stainless steel and aluminum due to their lower heat conductivity. Avoid excessive pressure and choose the appropriate abrasive for the task.

Welding is a very important stage of fabrication. However, for any welding process to be efficient and accurate the material must be prepared properly so that it is in the best possible condition for the next step. This can be achieved by effectively removing coatings such as paint, oils, greases, and rust (oxides).
It is crucial to remove impurities such as rust and mill scale when working with carbon steels. However, when working with stainless steels, it is often important to remove chromium oxide if a shiny decorative finish is required.
Nonferrous materials present their own challenges in the weld preparation process. For example, oxidation can take place very quickly on metals such as aluminum and titanium, and so there is a short time frame between surface cleaning and welding. If large areas are cleaned too early this often results in needing to rework the piece.
