The present disclosure relates to a portable production machine, a mobile terminal, a production system having a portable production machine and a mobile terminal, and a method for capturing data. According to aspects of the disclosure, on the production machine - which can be, for example, a welding machine or cutting machine - production data is automatically captured, organized into data sets, and converted into data set images, which are displayed on a display device. The displayed data set images are captured with a mobile terminal and transmitted to a central server. As a result, a plurality of production machines can be incorporated into a data system without the need for any changes to the hardware in the production machines.

An assembly is provided that includes first and second end plates adapted to be coaxially aligned when in use. One or more members extend from the end plates or an annular ring, the annular ring provided between the end plates, the other of the end plates or annular ring comprising one or more first slots at one end thereof to be aligned with and for receiving the one or more members of the first end plate, and one or more second slots at the other end thereof to be aligned with and for receiving the one or more members. Resilient sealing members are provided around the one or more members between the end plates and annular ring, and an urging mechanism urges the first and second end plates towards the annular ring to deform the first and second resilient sealing members to engage the inner wall of the pipe.

A robotic welding system comprises a supporting arm for attaching to a repositionable support structure, the supporting arm comprising a first mounting portion connectable to the repositionable support structure, and a second mounting portion rotatably coupled to the first mounting portion. A yaw rotary actuator rotates the second mounting portion about a yaw axis. A welding arm comprises a third mounting portion rotatably coupled to the second mounting portion of the supporting arm. A pitch rotary actuator rotates the third mounting portion about a pitch axis generally perpendicular to the yaw axis. A roll rotary actuator rotates a torch holder shaft about a roll axis generally perpendicular to the pitch axis. The shaft has a torch mounting portion for mounting a welding torch at an end thereof. A controller is operably coupled to the actuators to cause the welding torch to execute a welding pattern.

The invention provides a method for coaxially welding together two tubes. Axial ends of the tube walls of the respective tubes are machined in such a way that they have a stepped shape over at least a first part of the tube wall thicknesses. The stepped hapes complement each other. The method comprises the subsequent steps of A positioning the first tube and the second tube coaxially with respect to each other, wherein the machined axial ends contact each other at least over the first part of the first tube wall thickness and the first part of the second tube wall thickness and wherein the first stepped shape of the machined axial end of the first tube wall and the second stepped shape of the machined axial end of the second tube wall fit into each other, and wherein a seam is present between the first parts of the first tube and the second tube thicknesses, B fixating the first tube and the second tube at discrete positions over the circumference of the seam via attachment welds, C welding the first tube and the second tube to each other over the entire circumference of the first tube and the second tube, wherein the circumferential weld extends over the entire thickness of the first tube all and over the entire thickness of the second tube wall.

A method of automatically inspecting a weld bead deposited in a plurality of passes in a chamfer formed between two parts by performing the following steps: positioning at least one emission electromagnetic acoustic sensor on one side of the chamfer and at least one reception electromagnetic acoustic sensor on an opposite side of the chamfer, the ultrasound wave emission sensor being configured to emit Rayleigh surface waves; while depositing a pass, automatically moving the sensors to follow the movement of welding electrodes along the chamfer; activating the sensors while they are moving to enable the emission sensor to generate and emit Rayleigh waves towards the pass of the weld bead that is being deposited, the reception sensor receiving the ultrasound signals transmitted and/or reflected in said pass; and reiterating the operation for the entire pass of the weld bead.

Embodiments are directed to methods, systems, and apparatuses, for providing fittings capable of being orbitally welded. A system may include measuring components configured to measure a tubing thickness and measure a fitting thickness. The system may also include a processor configured to determine a difference in thickness between the measured tubing thickness and the measured fitting thickness and, based on the determined difference in thickness, determine an amount of fitting that is to be removed to reach a set, specified thickness that allows the fitting to be orbitally welded. The system may also include a facing tool configured to bevel and shape an end portion of the fitting according to the determined amount of fitting that is to be removed to reach the specified thickness and may include an orbital welder configured to orbitally weld the beveled end of the fitting to the tubing in a fusion socket weld.

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).
