Example Embodiment
[0032] Example 1
[0033] The invention provides an inner wall temperature detection and control device for non-melting electrode arc surfacing on a steel cylinder, including: a positioner, a steel cylinder on the positioner, a plasma welding gun, an infrared temperature sensor and the same A fixed fixture, a temperature collector, a temperature controller, a computer, and a robot control cabinet connected with the temperature controller. The infrared temperature sensor is used to detect the temperature information of the inner wall at the relative position of the welding gun; the temperature collector is used to filter and scale the temperature sensor signal; the computer converts the temperature information converted by the temperature collector into the form of a dynamic curve Display and compare the detected temperature with the preset temperature, calculate the adjusted welding current value, and output the control signal; the temperature controller transfers the control sig...
