Question

ultrasonic welding explosion welding add an answer item! add an answer item! answer bank uses a shock wave joins dissimilar metals high - frequency vibration used for plastics

Explanation:

• Ultrasonic welding relies on high-frequency mechanical vibration to generate frictional heat, which is ideal for joining plastics.
• Explosion welding uses the force of a controlled shock wave to create metallurgical bonds, often used to join dissimilar metals that are hard to weld with other methods.

Answer:

ultrasonic welding:

• high-frequency vibration
• used for plastics

explosion welding:

• uses a shock wave
• joins dissimilar metals
