Laser Welding Process, Weld Structure Observation, and Quality Control

We perform full-circumference and spot welding using a fiber laser welding machine.
Cross-section polishing is conducted to inspect the welding condition, including voids and blowholes.
Quality control is also carried out alongside these inspections.
