Sensors for arc welding are devices that monitor various parameters of the welding process to improve its efficiency, quality, and safety. They play a crucial role in automating and optimizing welding operations. Here are some key types of sensors and their functions in arc welding: 1. **Voltage Sensors**: Measure the arc voltage to provide feedback on the welding process. This helps in maintaining a stable arc and optimizing the energy input.

Welded sculpture refers to a three-dimensional artwork created by joining metal pieces together through welding techniques. This process involves applying heat to fuse metals, typically using electric arc welding, gas welding, or other methods, to create stable structures. Welded sculptures can vary widely in style, size, and complexity, ranging from abstract forms to representational figures. Artists often use materials such as steel, aluminum, bronze, or other metals that can withstand the welding process.

Welding defects are imperfections or discontinuities in a welded joint that can adversely affect the strength, integrity, and overall quality of the weld. These defects can arise from various factors such as improper welding techniques, material properties, environmental conditions, and equipment malfunctions. Welding defects can compromise the performance of a welded structure and may lead to failures under service conditions.

Saltstraumen is a strait located in Norway, near the town of Bodø in the Salten region. It is known for having one of the strongest tidal currents in the world, where the water flows through a narrow channel and creates powerful whirlpools and eddies. The tidal current can reach speeds of up to 20 knots (about 37 km/h or 23 mph) during peak flow, primarily caused by the difference in water levels between the adjacent fjords.

Michael E. Brown is an American astronomer known for his significant contributions to the field of planetary science. He is particularly recognized for his discovery of several trans-Neptunian objects, including Eris, which is one of the largest known dwarf planets in the Solar System and was instrumental in the debate over the definition of a planet. Brown has also played a key role in the discovery of other notable celestial bodies, such as Sedna and Haumea.

Christine Kirch is a notable figure in the field of astronomy, particularly known for her work in the study of stellar atmospheres and planetary systems.
