Different welding processes produce different impurities on and around the welding layer. These are mainly silicates, slag, spatter, and blue discoloration. All impurities can and should be completely removed.
Only after a complete cleaning should the next welding layer be applied. This is important because non-metallic inclusions have a reduced adhesiveness than the rest of the weld metal. This means that the next welding layer cannot adhere properly. Cracks can occur.
If the last welding layer (cover weld) is not cleaned and the component is later provided with a coating, coating defects and corrosion can occur at the inclusion points.
Las impurezas más difíciles de eliminar son la escoria y los silicatos. Se remueven con cepillos trenzados que tienen una acción de limpieza agresiva correspondiente.
Para las salpicaduras, se utilizan discos de láminas con corindón de circonio.
La decoloración azul se trata con cepillos con alambres más delgados y ondulados.
Nuestro diagrama a continuación muestra una asignación más precisa de los procesos de soldadura a la contaminación y la recomendación de herramientas.
Please pay attention:
Non-ferrous metals, stainless steel and aluminium should always be processed with brushes with stainless wire!
A brush with stainless wire should never be used in between for processing steel! Otherwise there is a risk of bimetallic corrosion (contact corrosion): Steel particles can be carried onto the workpiece made of precious metal and will corrode.
Each weld layer in a weld joint must be cleaned. The position of the weld (root, filler, or cover weld) influences which tool is suitable for cleaning.
Root seams are deep and are usually more difficult to reach because the weld joint is narrowest here. We recommend wheel brushes with a very narrow working width.
Filler seams can also be processed with wheel brushes. The working width can already be larger here.
Finally, the cover seam is cleaned with a wheel brush or a cup brush for wide seams.
Osborn’s premium quality Crimped Wire Cup Brushes feature an attached ¼” shank for use on air tools and electric portable tools. Manufactured with proprietary TufWire™ wire strands for uniform light-duty cleaning and lengthened brush life.
Osborn Cup Brushes provide quick, efficient cleaning of large metal surfaces. Manufactured with proprietary TufWire™ to offer high productivity and long life, and designed for use on portable power tools operating at high speeds.
Designed for heavy-duty tasks, Osborn High Speed Small Grinder Knot Wire Cup Brush feature proprietary TufWire™ for aggressive, yet uniform brushing action. This versatile brush makes quick work of scale removal, deburring, and weld cleaning, and is made for use on portable 4-1/2” and 5” grinders. Made in the USA.
Trust Osborn TufBrush™ products to get the toughest jobs done quickly and efficiently. Osborn’s unique design starts with quality wire. TufWire™, our proprietary wire strands, offers increased rigidity and aggressiveness. Combined with a unique knot design, TufBrush™ products consistently remove 60% more material than standard carbon steel wire varieties. Because of the brush’s state-of-the-art design, TufBrush products last twice as long as commodity brushes, which means less replacements and less downtime.
Tackle the toughest stringer bead weld cleaning projects with Osborn’s high-speed heavy-duty knot stringer brush. Brushes feature TY™ encapsulation, which allows only the tip of the wire to be exposed for minimum wire breakage and maximum aggression. Designed with specialty hardware that allows brush to be operated safely at very high speeds on electric and air tools. Made in the USA.
Constructed of pre-flared and bonded TufWire™ and encased in a rigid elastomer, Osborn’s TY™ Encapsulated Flared End Brush is designed for heavy-duty applications. The small brush diameter makes it an ideal choice for confined, tough-to-reach areas. Elastomer gradually wears back, exposing a short wire trim for maximum cut.
Osborn’s Crimped Wire End Brush is constructed of premium quality wire, flared to cover wide areas and irregular surfaces. Available in four brush diameters with steel or stainless steel wire to tackle a variety of tasks quickly and efficiently, including weld cleaning, rust and paint removal, polishing molds, tools and dies, and deburring. Includes ¼” shank for quick, convenient mounting on hand-held power tools.
Safely remove paint/coatings, busbar insulation and hose skiving with Osborn’s versatile narrow face, standard duty TY™ Encapsulated Wheel Brush. Made in the USA.
Osborn’s heavy duty TY™ Encapsulated Wheel Brush features a narrow face and crimped wire, ideal for standard stringer bead weld cleaning tasks. Premium quality wire firmly supported by elastomer provides uniform brush performance and lengthened life span. Made in the USA.
Osborn’s wide face, heavy duty TY™ Encapsulated Wheel Brush features maximum aggression for tougher applications, such as off-hand deburring and weld cleaning. Because wire is encapsulated, long wire breakage is minimized. Wide face covers larger surface areas quickly and efficiently. Made in the USA.
