Which tool is specifically designed for removing slag from welds?

The chipping hammer is specifically designed for removing slag from welds, making it an essential tool in welding processes. When a weld is performed, especially with stick welding, slag forms on the surface as a byproduct of the welding process. This slag needs to be removed to ensure a clean surface for inspection and any subsequent welding or finishing work. The chipping hammer is equipped with a sturdy metal head and is used to strike the slag, chipping it away easily. This tool is particularly effective due to its design, allowing operators to access and remove slag effectively without damaging the underlying weld.

In contrast, other tools such as a pry bar, wire brush, or sander are not specialized for this task. The pry bar is generally used for prying apart materials rather than cleaning. A wire brush can help in cleaning surfaces, but it is not specifically designed for slag removal and lacks the focused striking capability of a chipping hammer. Similarly, a sander is intended for smoothing surfaces and would not effectively remove slag from welds. Therefore, the chipping hammer stands out as the appropriate tool for this specific job in the welding process.
