Welding protection device and connecting hose

The utility model provides a welding protection device and a connecting hose, the welding protection device comprises a device body sleeved outside a metal pipe, a cavity for cooling water to pass through is arranged between the device body and the metal pipe, and the device body is also provided with a water inlet hole and a water outlet hole which are communicated with the cavity. Such an arrangement, cooling water can continuously enter the cavity from the water inlet hole; after the metal pipe is cooled, the water flows out from the water outlet hole; circulating cooling water is formed inthe cavity, the problem that the connecting hose cannot be continuously cooled in the prior art is solved, the metal pipe can be effectively and continuously cooled, welding high temperature is prevented from being conducted to the rubber pipe through the metal pipe, and therefore the rubber pipe of the connecting hose is protected against high-temperature damage. 本实用新型提供了一种焊接保护装置及连接软管，其中焊接保护装置包括套设于金属管外的装置本体，装置本体与金属管之间设有
