Abstract
Part of the upper flange at the end portion of an I-beam is removed therefrom by cutting through the flange with a plasma-arc torch, the torch also forming a vertical cut through the lower flange of the beam. Thereafter, a shearing punch shears through the web of the beam to remove the lower flange from the end portion of the beam. Because a portion of the upper flange is removed from the beam prior to the shearing operation, the punch does not engage any substantial part of the upper flange and thus the punch may effect shearing of the web along a line located in close proximity to the junction of the web and the flanges.
