The invention belongs to the technical field of metal cutting, and discloses a punching device and a punching method for an arcing hole of an extra-thick plate. The perforating device is composed of a protective cover, an air outlet pipe, a nut, a connector, a rubber hose, a hose clamp, an air supply pipe, a control valve and an oxygen bottle. The perforating process method comprises the five steps of positioning, preparing, preheating, perforating and cleaning. According to the steel plate perforating machine, perforating operation can be directly carried out on a steel plate, the steel plate penetrating thickness can reach 340 mm, occupation of large machining equipment is avoided, the transfer cost is saved, the safety is high, operation stop caused by blockage is avoided, the perforating efficiency is extremely high, the perforating cost is extremely low, the production cost can be effectively reduced, and the production efficiency can be remarkably improved. 本发明属于金属切割技术领域，公开一种特厚板起弧孔穿孔装置及穿孔方法。所述穿孔装置由保护罩、出
