Would a nylon wheel or nylon bristles used for cleaning a joint prior to welding create any kind of negative effect on the weld?

Reply:I understand that often the phrase 'was that supposed to be a joke?' is often taken aggressively, but it was asked without emotion. I assume you can indeed clean things with a swiftly spinning nylon brush, but I was concerned (justified) that nylon would be a poor choice for cleaning mediums.I've seen what appears to be brass wire wheel brushes, would those be a bad idea? I am guessing they are steel wire bristles with a brass coating to prevent rusting.I recently purchased a hand held reciprocating saw, drilled a few holes through a blade and screwed on a stainless steel brush and thought, "If iron man ever needed a tooth brush". The brush doesn't work too bad, I think courser wires would be better. I am trying to find a middle grind for welding surface prep, I've spent a lot of time with a wire brush in hand and body parts eventually get sore or fatigued. I love flap discs, but often, no matter how careful I am, I remove a bit more material than intended around corners and edges. Not long after making this little reciprocating saw tool modification, I found something extremely similar at a hardware store, I had found something else similar to this online, but it came in a much more expensive set of attachments, all I wanted was the wire brush. The good news is, when finding this particular set at a hardware store, I found that it also had a few filing attachments, that seems like it might be useful. What I found was called 'Reciprotools'.One might argue that the excess material removed via flap disc is likely insignificant, but on thinner gauge material, I feel it's worth caring.

Reply:Nylon melts fairly easily. I'd think anything close to high speed would probably soften or even melt the bristles then leave a residue. Good nylon also maintains a flame once lit. Nice soft, difficult to see flame much like an alcohol flame. I'd be afraid that anything requiring absolute cleanliness would be compromised if a nylon wheel was used."The things that will destroy America are prosperity at any price, peace at any price, safety first instead of duty first, the love of soft living and the get rich quick theory of life." -Theodore Roosevelt
