Abstract (en)
[origin: DE19937277A1] The invention relates to a method for removing dents from sheet metal parts, in particular, from painted parts of a vehicle body, whereby the sheet metal part (3) is locally heated, in an essentially contactless manner, in the area of a dent (B) such that a mechanical tension gradient generated by the local heating causes the dent to straighten back into the original shape of the sheet metal part.
