Provided is a handheld device and a method for detecting weld defects on a weld surface. The handheld device projects a thin beam laser light on the weld surface using a laser emitter. A processor receives the projected thin beam laser light from a laser receiving sensor, which indicates captured contours of the weld surface. The captured contours are processed to filter laser lines and extract contours. The extracted contours are utilized to classify a type of weld surface such as, surface joints, butt joints, corner joints, and tee joints. The processor, upon classifying, automatically adjusts angle and position of the laser light to be projected on the weld surface and detects deviation patterns by employing an ensemble of a laser line extraction process and a pixel width measurement process. The processor determines the detected deviation patterns as one or more defects on the weld surface that is being inspected.
