Disclosed are an automatic continuous operation robot for laying large-diameter pipelines and an operating method therefor. The operation robot comprises a platform, a main frame (1), an operation room, a navigation subsystem (1002), a pipe grabbing and conveying subsystem (3), a pipe end face pre-treatment subsystem (4), an on-line measurement subsystem, a pipe supporting subsystem, a welding and welding quality inspection subsystem (5), and a control system. The operating method comprises: first detecting and grabbing a pipe, then performing groove machining on the pipe, fitting the welding end faces of the current pipe and a previous pipe, then putting down the pipe, finely adjusting and fixedly connecting the two pipes, and finally, welding the two pipes. The automatic continuous operation robot for laying large-diameter pipelines has a high degree of automation and high working efficiency, and the laying period is short.
