[0032] The device body 1 has a limiting mechanism 2 connected to its upper end. By installing the limiting mechanism 2 at the upper end of the device body 1, the ultra-thick steel plate can be limited by auxiliary means, which facilitates welding work.

[0033] The auxiliary mechanism 3 is arranged at the upper end of the device body 1 to assist in temperature control and crack prevention. The auxiliary mechanism 3 includes a thermostat 31. A temperature sensor 32 is installed on the device body 1. The front end of the device body 1 is connected to a temperature controller 33. The actual temperature of the welding steel plate is detected by the temperature sensor 32, and the detected signal is fed back to the temperature controller 33, so that the temperature sensor 32 heats and maintains the temperature of the steel plate after welding according to the instruction of the temperature controller 33.
