General description These 4X M8 Thread Fiber Welding Cleaning Brushes are specifically designed for cleaning passivated and polished steel welds after TIG or MIG welding. They effectively remove discoloration caused by the welding process on stainless steel materials such as V2A, V4A, AISI 206, AISI 304, AISI 316, and similar hardened and tempered materials. The brushes are suitable for electrolytic pickling and can be used with a mordant solution. Technical specifications Type: M8 Thread Fiber Brush Material: Copper + Fiber Temperature resistance: Up to 160°C Package Contents: 4 x Brush Measurement allowed error: +/- 1-3 cm Usage These brushes are intended for cleaning and pickling weld seams from the WIG, MIG, and TIG welding processes, as well as for aluminum. They can also be used for passivation and marking when combined with a suitable fluid. For optimal performance and longevity, it is recommended to use them within a PTFE tube and to keep the working end as short as possible.
