![]() Using a carbon steel brush on those materials can cause contamination or after-rust and will require rework. A stainless steel brush should be used on any type of stainless steel or aluminum. It’s critical for productivity and quality to match the wire brush to the base material type. Several factors play a role in choosing the right wire brush for the job, including the type and size of the weld being cleaned, the base material and the desired surface finish. Using a heavy-gauge wire on aluminum can alter the base material and change the appearance of the material, but a fine wire removes discoloration without removing base material. Fine stainless steel wires are well-suited for cleaning aluminum, stainless steel, and TIG welds. It’s recommended to use the finest wire gauge possible that still gets the job done. ![]() Compared to a knotted wire, a crimped wire offers more flexibility but is less aggressive. If the knot is twisted tightly to the top - without a tuft - the cleaning action is more aggressive, which can be good for cleaning V-groove welds. If the tuft at the top of the knot is spread out, the wider face width is good for cleaning a larger surface area. The general rule of thumb is the tighter the twist of the wire, the more aggressively it cleans. When a straight wire is twisted into a knot, the wire becomes stiffer and therefore more aggressive. But using a handheld brush to clean a larger weld is very inefficient.Įach type of wire brush is available in various configurations, including knotted or crimped wire. Hand brushes can be used for small welds, when you need to knock off slag with a few swipes between weld passes.End brushes with fine, crimped wires are good for light surface cleaning on TIG welds as well. End brushes can be used for cleaning tight, hard-to-reach areas such as T-joints.These brushes aren’t typically used for interpass weld cleaning because of their size. Cup brushes are good for weld preparation, especially when you need to clean a larger area or wide surface.Wire wheel brushes are the workhorses of this product category, offering great versatility for many pre-weld, interpass, and post-weld cleaning jobs.Some of the main types of wire brushes used for weld cleaning: Wire brushes provide efficient cleaning action for surface prep and finishing without removing base material. Many welding applications require pre-weld, interpass, and post-weld cleaning. Learn how to choose the right wire brush for your application and some tips for improving productivity in weld cleaning. There are many types and styles of wire brushes - each with their own benefits and best practices for use. They’re versatile and effective tools for removing surface contamination, such as rust or heat discoloration, without removing base material. Wire brushes are a staple for weld cleaning. The environment is also important when choosing brushing due to corrosion and hazardous scenarios that may result from spark formati on.How to Clean Welds Faster With a Wire Brush By David Jescovitch, Abrasive Specialist Manager, and David Blain, District Sales Manager, Weiler Abrasives Group Brush hardness and the pressure exerted are the main control elements whenever brushing is used in surface preparation. ![]() Therefore, wire brushing is often followed by brush coating or painting.īrushing is eventually not very effective as its results prove to be non-uniform. Pits and crevices can accumulate salts and other impurities that may encourage corrosion. It should be noted that the corrosion resistance of a substrate will decrease with increasing roughness as a result of the increase in residual forces that may lead to stress-corrosion cracking. For example, brushing stainless steel or aluminum requires stainless steel or aluminum brush wires to prevent corrosion. Different wire brushes are used depending on the substrate. In surface modification such as painting or coating, there must be some amount of roughness for the protection material to adhere to the substrate. Corrosionpedia Explains Wire Brush Cleaning
