Patent ID: 7717315

Claim:
A method for production of a gas turbine blade component having a surface, comprising: introducing a filling element into the component through a first side of the surface of the component; connecting the filling element to the component by a soldering method; during the soldering method of the filling element and component, using a an M shaped holder that connects the filling element to the component temporarily, wherein the holder has a first holding point on the first side of the surface of the component and a second holding point on the filling element; and removing the holder after the filling element and component have been fixed by soldering, wherein the filling element is introduced into a groove in the component, and between the filling element and the component in the grove there is a gap, wherein a first end of the M shape of the holder is fixed to a first holding point on the component, a middle of the M shape of the holder is fixed to a second holding point on the filling element, a second end of the M shape of the holder is fixed to a third holding point on the component, and the filling element is a permanent plug wherein the filling element is arranged such that a further gap is formed between a bottom of the filling element and a base of the groove in the component, wherein the further gap traverses the entirety of the base of the filling element.
