ABSTRACT:
A scraper tool for removing material such as surface treatments, metal coatings, and other material layers from an edge region of a metal work piece where they could potentially contaminate a nearby weld. According to one embodiment, the scraper tool includes a body having a base portion and a tab portion, and several scraping elements attached to the base portion. During operation, the scraping elements scrape one or more surfaces of the edge region so that the depth to which the scraping element engage the metal work piece is generally affected by the amount of rotation of the scraper tool about a pivot axis.
