Ultrasonic
Ultrasonic refers to a modern welding technique that uses high-frequency sound waves instead of heat to join materials together. Think of it like using sound vibrations to create a very strong bond between pieces of metal or plastic. This method is popular in many industries because it's clean, efficient, and works well for delicate materials that might be damaged by traditional heat welding. When you see this term in resumes, it usually means the candidate has experience with advanced welding equipment and precise manufacturing processes.
