Edge Rounding & Fiber Burn

Physical-chemical mechanism of action

Edge rounding reduces stresses at sharp edges that could occur during welding. Fiber burn-off burns combustible materials to remove them and ensure that no flames are generated.

Metallurgical relevance & risks in welding

Sharp edges can cause high stresses and lead to cracks. Combustible materials can cause flames and damage to the weld. Both processes protect the workpieces and the metal structure.

Workshop practice & instructions

Before welding, round off sharp edges with an angle grinder. Remove combustible materials like plastics or paper before starting the welding process.
