The welding done in a tube or pipe mill ruins the galvanic or aluminum coating intended to keep the product corrosion-free, so remetallizing the weld seam is a common practice. Remetallizing creates a large amount of metal dust, which usually is considered a big nuisance and an expensive disposal headache, but in some cases it can be recycled for a profit.

OHSA seems to be taking an increased interest in worker safety and, according to OMB Watch, has been citing an increasing number of workplace violations. Tube and pipe producers who remetallize their product pay particular attention to OSHA Directive Number CPL 03-00-008, which deals with a hazard specific to remetallizing operations: explosive dust.
