  "Poutrelle soudée ". 



   On sait que l'on ondule ou que l'on pratique de.enfen- cements ou creux de forme autre que les ondulations dans les ailes des poutrelles laminées d'une pièce, en vue d'accroître leur moment de résistance. D'autre part, les poutrelles sou- dées, c'est-a-dire les poutrelles qui se composent d'une tôle d'acier et d'une bride ou de brides assemblées avec elle par soudage, dans lesquelles la tôle d'acier est guidée entre des traverses prévues sur les brides, sont connues. L'assemblage s'opère alors soit de la façon connue par emploi de matière de soudage additionnelle, soit en faisant fondre les traver- ses.

   L'invention concerne des poutrelles soudées, c'est-à-dire   @

  "Welded beam".



   It is known that one corrugation or practice of indentations or hollows of a shape other than the corrugations in the flanges of the rolled beams of a piece, in order to increase their moment of resistance. On the other hand, welded beams, that is to say beams which consist of a steel sheet and a flange or flanges assembled with it by welding, in which the sheet of steel is guided between cross members provided on the flanges, are known. The assembly is then carried out either in the known manner by using additional welding material, or by melting the crossbars.

   The invention relates to welded beams, that is to say @
