1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Automated welding robots face challenges in unstructured field conditions, limiting their use in complex steel structures like pipelines, bridges, and buildings. Expandable convoluted pipe (ECP) poses unique welding challenges due to their confined spaces and irregular shapes. Manually performed butt-welding for ECPs is inefficient. To address this, a flexible mobile welding robot tailored for ECPs was developed. This paper analyses the robot's structure, working principle, and drive system, minimizing drive chain force-velocity angles to reduce power loss. Transmission modelling, finite element analysis, and life prediction using the Archard model yield promising results. Virtual simulations and prototype welding tests validate the robot's design, with satisfactory weld formation. Expanding the ECP with a hydraulic pump verifies the robot's reliability with no weld cracks observed.
