At present, a heat shield welded on an exhaust pipeline generally adopts a front-back welding mode or a left-right welding mode. When exhaust gas is exhausted, due to the fact that temperatures of the front and the back of an automobile exhaust pipeline are inconsistent, the welding seams between exhaust pipes are different in thermal expansion degree, the thermal stress is different, due to the characteristic of welding processing, the mechanical performance of the welding part of a component is poor, the welding seams are prone to cracking after vibration is applied, and even the heat shield can fall off from the exhaust pipe when the heat shield is serious, so that a non-welding exhaust pipe heat shield assembly is needed.
