METHOD OF MAKING A HOLE ON A TUBE BY FLUORESCIPTING, PARTICULARLY FOR THE IMPLANTATION OF MEASURING PROBES ON EXHAUST DEVICES

摘要

P This method of flaking a hole in a tube (1) is characterized in that, prior to flaking, a flat stamping or recess (2) is made in the tube intended to form a small flat surface (3) on which the hole will be made by drilling. The removal is preferably carried out hot, and more preferably using a perforator. Before the drilling of the hole, a washer is placed in the recess which has just been produced. Thanks to the friction and the rise in temperature due to fluoperimentation (around 1000 ° C), the washer will be welded to the tube and part of its constituent material can be used for the development by creep of the barrel and the collar. / P
