Abstract
Methods of producing a pipe include curling a skelp into a cylindrical shape by bringing laterally opposed edges of the skelp together to form a seam, butt welding the seam to define the pipe downstream of the skelp, thereby leaving a radially inwardly extending weld bead. The weld bead is deburred off the pipe according to a depth of cut of a cutting tool. The depth of cut may be adjusted during deburring, and/or rotation of the cutting tool may be adjusted during deburring. The methods may be carried out using one or both of an adjustment device carried by a housing to pivot an adjustment member for adjustment of an upstream guide to adjust a depth of cut of the cutting tool into the weld bead, or an adjustment device carried by the housing and coupled to the cutting tool to rotate the cutting tool during deburring.
