Abstract
A silencer for reducing gas noise in a combustion engine intake system has a tubular casing with a first casing part and a second casing part connected to each other by a weld seam to form an outer casing wall, wherein the weld seam is a part of the outer casing wall. A third part for compensating gas noise is positioned inside the tubular casing. The third part is arranged in the tubular casing such that an annular cavity is formed by the third part and the outer casing wall. A weld flash protrudes from an inner surface of the outer casing wall into the annular cavity and is contained therein. The silencer is produced in a single welding process in which the first and second casing parts are connected to each other to form the outer casing wall and the third part is connected to the tubular casing.
