Laser Keyhole Welding (레이저 키홀 용접)

진동이 없는 레이저 키홀 용접

진동이 없는 레이저 용접의 문제점

  • 틈새 조건에서 허용 오차가 낮아지는 좁은 조인트 폭
  • 레이저가 꺼질 때 끝의 큰 구멍
  • 속도가 높아 침투가 불충분 할 수 있음
  • 사용 가능한 레이저 출력으로부터 제한을 받음

진동이 있는 레이저 랩 용접

  • 키홀의 붕괴를 방지하는 고속 스캐닝이 가능
    – 다공성을 최소화함
  • 인터페이스 간극에서 브리지 간격을 조정하여 조인트 폭을 조정할 수 있는 유연성을 제공함

진동이 있는 레이저 용접의 장점

  • 성능 및 스타일링을 위한 제품을 개선
  • 최초의 품질에서 요구를 충족시키기위해 결함을 감소
  • 성능의 요구 사항을 충족시킬 수 있는 맞춤형 용접 형상

진동 용접 : 실험 결과

모델 검증

한 사이클 내의 키홀의 움직임

  • 진동이 없을 때 : 일관된 전도 또는 키홀 용접
  • 진동이 있을 때 : 전도 용접을 하며 경로 및 시간에 따라 한 번의 주기 내에서 얕은 키홀과 깊은 키홀이 용접 간 전환 가능

진동을 이용한 레이저 용접의 장점

  • 진동을 이용한 최초 품질이 향상됨
  • 키홀로 인한 다공성을 피하면서 빠른 용접 속도를 가능하게 함
  • 전력 변조가 사용되지 않는 경우에 각 주기 내에서 키홀과 전도 모델 간의 전환이 가능
  • 진동의 매개 변수를 변경하여 중요한 용접의 너겟 치수 및 강도의 조정이 가능
  • 시트 간의 틈 브리징을 개선

What’s happening at the melt pool?/레이저 가공

Laser keyhole welding

레이저 키홀(Keyhole) 가공(No oscillations/진동 고려하지 않을 경우)

높은 속도에서 다공성을 감소시키는 경우(Reduced porosity at high speed-mechanism)

고속 레이저 가공(진동 고려하지 않음)해석 시 고려사항

  • 틈새 조건에 대한 허용 오차가 낮아지는 좁은 조인트(Joint) 너비
  • 레이저가 꺼질 때 큰 끝 분화구(Large end crater)
  • 속도가 높을 때 불충분한 침투(Penetration)
  • 제한된 사용가능한 레이저 출력 : 6kW

진동을 고려한 레이저 랩(Lap) 용접

  • 키홀(Keyhole) 붕괴를 방지하는 고속 스캐닝 가능
    – 다공성(Porosity) 최소화
  • 인터페이스 간극(Interface gaps)에서 브리지 간격(Bridge gaps)을 조정하여 조인트(Joint) 폭을 조정할 수 있는 유연성 제공

진동을 고려한 레이저 용접 : 실험 결과와 비교

모델 검증

사이클(One cycle) 내에서 키홀(Keyhole) 역학

  • 진동을 고려하지 않을 경우 : 일관된 전도 또는 키홀 용접
  • 진동을 고려할 경우 : 경로와 일정에 따라 한 번의 주기내에서 전도 용접, 얕은 키홀(Keyhole)과 깊은 키홀(Keyhole) 용접 간 전환 가능

진동을 고려한 레이저 가공의 이점

  • 진동을 통한 최초 품질 향상
  • 키홀(Keyhole)로 인한 다공성(Porosity)을 피하면서 높은 용접 속도 가능
  • 전력 변조가 사용되지 않는 경우, 각 주기내에서 키홀(Keyhole) 및 전도 모델간 전환
  • 진동 매개 변수 변경을 통해 중요 용접 너겟(Nugget) 치수 및 강도 조정 가능
  • 시트 간 틈 브리징(Gap gridging) 개선
