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

Friction stir spot welding (FSSW) has shown promising potential for joining sheets and other geometries of metals as well as polymers. For thermoplastic materials, especially carbon black reinforced high-density polyethylene (HDPE-CB), the FSSW technique has shown promising results. However, in the published literature, most of the FSSW studies on thermoplastic materials have focused on single-spot joints. The current paper aims to investigate and develop a framework for multi-spot based FSSW joints. Based on the study, it is evident that the strength of the weld increases with the number of weld spots, and the weld direction plays a crucial role in determining weld performance. The double-side weld configuration of T4 weld spots achieved the maximum peak load of 5207 N. Additionally, edge distance and weld spacing were found to significantly influence peak load, demonstrating a proportional relationship. Overall, this study pioneers the investigation of weld spot inclination and spacing in multi-spot based FSSW of thermoplastic polymers, providing insights into their influence on joint strength and failure mechanisms. The findings highlight critical role of weld alignment and optimized spacing in enhancing load distribution and maximizing the tensile performance of lap joints.
