Welding and inspection are critical processes in manufacturing and construction, ensuring the integrity and durability of materials and structures. Welding involves joining materials, typically metals, through heat, pressure, or both, creating strong bonds that are essential for various industrial applications. Common welding techniques include MIG, TIG, and arc welding. Inspection ensures the quality and safety of welded joints, using methods like visual inspection, ultrasonic testing, X-ray inspection, and magnetic particle testing to detect defects such as cracks, porosity, and inconsistencies. These practices are crucial in industries like aerospace, automotive, and construction, where structural reliability and safety are paramount.
