The bead removing tool (18) can remove beads from the asymmetrical sectional grooved steel rail (G).

welds attacked after the reinforcement had been planed down

In one specific embodiment, the sequence is determined by numerical analysis of a plurality of weld bead sequences to determine the weld bead sequence.

The weld warpage and the weld tension are minimized by offsetting the weld lines.

All the segments have straight weld seams, so that workers perform construction at a high speed, and deformation of the weld seams can be controlled easily.

The welding seam contour calculation component is used for calculating the detected welding seam contours.

The welding beads arranged between the pockets make up inflexion points.

This high aspect ratio reduces the number of weld beads needed to build the weld joint.

The welding parameter setting component is used for setting welding parameters based on the calculated welding seam contours and the calculated welding trajectory points.

The welding trajectory point calculation component is used for calculating welding trajectory points based on the calculated welding seam contours.

The welding seam contour detection component is used for detecting an initial welding seam contour and detecting remaining welding seam contours after welding each layer of the welding seam.

The machines (5, 6) for machining the welding beads are arranged in parallel.

In this way, even complex, three-dimensional welding seams (13) can be formed using a straight rail (14), which can be used universally for differing welding seams (13) having diverging progressions.

It is then purified and cooled to remove excess waxes.

Said configuration provides a weld bead-shaping device capable of shaping weld beads with high precision.
