Welding stainless steel requires special attention to the type of burn used, as this material has unique properties that can affect the outcome of the welding process. Stainless steel is known for its resistance to corrosion and oxidation, but it also has a tendency to become brittle when subjected to excessive heat or improper welding techniques.

Using the correct type of burn, which refers to the heat and manner in which the welding arc interacts with the base material, is crucial for ensuring that the metal maintains its integrity and desired mechanical properties. The heat input must be carefully controlled to avoid overheating, which can lead to issues such as warping, reduced corrosion resistance, and a compromised microstructure.

Moreover, the type of filler material and its compatibility with the stainless steel being welded is also significant, as this can influence the weld's strength and corrosion resistance. Therefore, attention to the burn type not only ensures a successful weld but also preserves the unique characteristics of stainless steel.
