A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members.

A welding support block supports, from the rear surface of a joint to be welded, a weld pool created during a welding process. The welding support block comprises a block of metal and an outer layer of ceramic material providing a supporting surface. The ceramic material layer has a thickness between 0.25 mm and 1.5 mm. The metal material immediately beneath the ceramic material layer is made of steel. An internal line-up clamp for holding pipes in end-to-end alignment ready for welding may include multiple such welding support blocks. The use of such welding support blocks is particularly useful when laying a sour service carrying pipeline (high H.sub.2S content).
