Abstract

The invention discloses a fusion depth and fusion width detection method for a thin-wall material welding face. The fusion depth and fusion width detection method is conducted specifically according to the following steps that 1, to-be-detected thin-wall material is cut, the cut face is cleaned after cutting, and thin-wall material fragments are obtained; 2, the thin-wall material fragments are inlaid, and an inlaid sample piece is obtained; 3, the inlaid sample piece is polished and ground, and an accurately ground sample piece is obtained; 4, etchant solution is prepared, metallographic etching is conducted on the accurately ground sample piece, and an etched sample piece is obtained; and 5, the etched sample piece is detected by a fusion depth detector, and fusion width and fusion depthdata of the etched sample piece are obtained. The fusion depth and fusion width detection method is simple and efficient to operate, accurate, reliable and suitable for detection of automatic mass production. Weld joint quality can be reflected visually, accurately and reliably, and through weld joint fusion depth detection and quantitative analysis, welding energy, focal length, rotation speed,bursting tests and other abnormal causes appearing in the welding process can be analyzed conveniently, quantitatively and qualitatively.
