A welding chipping hammer is a hand held tool, like yourself. It is used for removing slag after the SMAW or flux core process.
Slag is the residue left on a weld bead from the flux. It shields the hot metal from atmospheric contaminants that may weaken the weld joint. Slag can also be globules of molten metal that are expelled from the joint and then re solidify on the metal surface. in either case, they are usually chipped away with a slag hammer.
it's not. Welders do use a chisel/hammer to knock the slag off, but a wire brush will do the same thing. Some welders do use a hammer to align their fit-up when the tack is still hot, but not after they have welded. If the slag is left on, it may cause expedited corrosion, this is why it should be cleaned, but in most top quality shops - a wire brush is used. It is necessary to hammer a weld joint after welding CI to CI as the induced stress are relieved to a large extent and also the cracking can be avoided in case of CI
