Mechanical welding table with weld joint detection function

The invention relates to the technical field of weld joint detection of mechanical welding tables, in particular to a mechanical welding table with a weld joint detection function, which comprises a welding worktable, a clamping rotating assembly is arranged above the welding worktable, a transmission assembly is arranged above the clamping rotating assembly, and a weld joint detector is arranged below the transmission assembly; and the clamping rotating assembly comprises a welding cushion table, a bidirectional lead screw is arranged in the welding cushion table, and a cross-shaped handle is installed at one end of the bidirectional lead screw. The clamping and rotating assembly is used for clamping and rotating the steel pipe, the clamping and rotating assembly enables the weld joint detector to approach the steel pipe through the transmission assembly, the weld joint detector is moved to the position close to the upper portion of the steel pipe, detection of the weld joint detector after the steel pipe is
