The invention discloses a stamping-welding line comprising a feeding mechanism, a cutting switching mechanism, a stamping detection mechanism, a clamping detection mechanism, a welding mechanism, a welding detection mechanism, a main electrical cabinet and area sensors, all mounted on the ground in a factory. The feeding mechanism, the cutting switching mechanism and the stamping detection mechanism are transversely arranged side by side on the ground in the factory; the clamping detection mechanism and the welding mechanism are disposed in order in the front of the stamping detection mechanism; the welding detection mechanism and the main electrical cabinet are disposed in order on the left of the welding mechanism; the area sensors are arranged in a rectangular form around; the feeding mechanism comprises a winding feeder and a straightener; the winding feeder is provided with a roll of material; the roll of material is connected to the cutting switching mechanism through the straightener. The stamping-welding line has the advantages that the stamping-welding efficiency is high, production stability is good, product scrap rate is low, and total production efficiency is high.
