Acoustic underwater welding

Acoustic underwater welding is a technique that uses high-frequency sound waves to join metal pieces beneath the water's surface. Instead of traditional heat, ultrasonic vibrations create localized friction and heat at the weld area, enabling strong, durable bonds even when submerged. This method minimizes the problems caused by water, such as corrosion and contamination, and allows repairs to be made directly underwater, saving time and reducing environmental impact. It's a specialized, effective solution for maintaining ships, pipelines, and offshore structures in aquatic environments.
