摘要:
A burr formed between two pipe sections when they are welded together is removed by displacement of a cutting tool inside the welded pipe sections and a second cutting tool outside the welded sections. A burr catcher is coupled to the inner cutting tool to catch the portion of the burr which is removed from the welded joint to enable its subsequent removal. The cutting tool may be free falling or it may be coupled to a free falling weight system, so as to move upwardly in the pipe sections or it may be driven externally by a hydraulic cylinder.
