The invention relates to the technical field of weld joint
processing and provides a weld joint excess
weld metal processing device and a weld joint
processing method. The device comprises a base frame, a milling unit, a
polishing unit and a burnishing unit; the milling unit comprises a
milling cutter, a milling buffer floating part, a
milling cutter fixing board and a milling drive part arrangedon the
milling cutter fixing board; the milling buffer floating part is used for driving the milling cutter fixing board to vertically move according to the excess
weld metal of a weld joint to be milled; the
polishing unit comprises a flap disc, a
polishing drive part and a polishing buffer floating part; the polishing buffer floating part is used for driving the polishing drive part to vertically move according to the excess
weld metal of the weld joint to be polished; and the burnishing unit comprises a
brush head, a burnishing drive part and a burnishing buffer floating part which is usedfor driving the burnishing drive part to vertically move according to the excess weld
metal of the weld joint to be burnished. Through the method, super-long weld joints of twenty meters or longer canbe processed continuously without interruption, milling, polishing and burnishing procedures can be finished at a time, and the processing quality can also be ensured.
