A device for producing or building up a metal part by sintering and laser fusion, the device including a laser beam generator, a mechanism for deflecting the beam to scan a surface of the part to be produced, a sintering pan including a metal powder used to cover the surface of the part and to be melted by the laser beam to thicken the part, and at least one mechanism for heating powder contained in an area of the sintering pan by induction.

Sintering and laser fusion device, comprising a means for heating powder by induction

The method is used to attach the various parts of a 'T' assembly using a single laser welding pass from the outside of the 'T' assembly. Welding is done with a bifocal welding head () the two axes () of which are parallel to a surface of the part forming the &#x201c;T&#x201d; stem (), the weld being made along the entire length of the assembly. To be used when manufacturing vanes for a turbo jet fan duct.
