Laser welding

This research from Shanghai Jiao Tong University proposes a novel Fusiform Attention Network (FANet) for the real-time visual monitoring of penetration status in laser welding. By integrating Ternary Multi-head Linear Attention (TMLA), the model effectively aligns its receptive field with the physical geometry of the molten pool, balancing local detail extraction (spatter, plasma) with long-range morphological perception (molten pool length). The network achieves a high recognition accuracy of 93.24% with an end-to-end latency of only 5.41ms, meeting the stringent requirements for high-speed online industrial monitoring (100 FPS) and providing a robust solution for closed-loop quality control in automotive, aerospace, and shipbuilding industries.

The article reviews the latest developments and future prospects of beam shaping technology in laser welding. It discusses how different beam morphologies—such as Gaussian, elliptical, flat-top, and dual-mode beams—control molten pool dynamics to reduce defects like porosity and spatter, especially in high-reflectivity materials like aluminum and copper.

This article analyzes the mechanism and influencing factors of solidification cracking in laser welding. It introduces several strategies, including grain structure refinement, beam oscillation, and dual-laser sources, to suppress cracking. These methods provide theoretical and practical support for improving the quality and reliability of laser-welded joints.

Laser welding is a critical technology in modern manufacturing, where the melt pool's formation and solidification determine weld quality and material properties. The article explores how factors such as fluid dynamics, microstructure evolution, and pore formation mechanisms influence welding outcomes, with a focus on optimizing welding parameters. Understanding these dynamics allows for improved control over welding quality, leading to more efficient and reliable manufacturing processes.

Laser welding machine with its high-quality characteristics and perfect role is commonly used in the production of a variety of goods processing production, high-quality and effective laser welding machine not only to ensure the personal safety of the workers, but also in a more limited period of ti

First, automatic laser welding machine is generally composed of five parts1. The main machine is mainly a laser power supply. The laser power supply controls the xenon lamp, so that the xenon lamp flashes and emits light to excite the laser bar through a series of optical systems, so that the laser

In the enterprise processing production, some will use to the laser and other equipment for processing, and some will be due to the processing of the reason and produce dust and other substances, in both cases, no matter which one will be on the processing personnel eye health hazards, so in the pro

Beam ShapingWhen we talk about Beam Shaping, we often refer to the use of beam shaping lenses, lenses, microlenses or different shaped fibers to achieve a homogenizing effect on the spot. Here we introduce a new method: BrightLine welding technology from TRUMP, using a 2-in-1 fiber (Figure 1), which
