A welding chamber is arranged on the left side of the fixed placement plate, and a flange mounting plate is installed on the left side of the welding chamber. Sliding grooves are provided at the connection parts of the flange mounting plate and the activity placement plate with the device bottom plate, and sliding blocks are arranged inside the sliding grooves. The sliding blocks are fixedly connected to the flange mounting plate and the activity placement plate respectively; rolling grooves are opened inside the fixed placement plate and the activity placement plate, and rolling balls are installed inside the rolling grooves. In this steel-lined tetrafluoroethylene pipe welding device, the fixed placement plate and the activity placement plate can support the steel-lined tetrafluoroethylene pipe, and the activity placement plate can slide on the device bottom plate, so as to be freely adjusted according to steel-lined tetrafluoroethylene pipes of different lengths, which is convenient to use.
