INDUCTION BRAZING METHOD OF A CUTTING TOOL, SUCH AS A CARBIDE OR SIMILAR PLATEBOARD, ON A STEEL SUPPORT

摘要

The invention relates to a process for inductively brazing a cutting tool (2), such as a carbide insert or the like, on a steel support (1) of a working device of the earth or other abrasive material, such as a ploughshare (3). BR/ This method is characterized in that: BR/ - the assembly is raised, steel support (1) and cutting tool (2), at a temperature substantially corresponding to the austenitization temperature (TA) of the steel grade of the support (1), while between the latter and the cutting tool (2) is interposed a filler metal of which the melting temperature (Tf) lies in a range between said austenitization temperature (TA) and a temperature at most 30% lower; BR/ - then after a cooling period allowing the filler metal to to change from the liquid state to at least the plastic state, the quenching of the whole under gaseous fluid and / or liquid.
