펄스 레이저 용접은 레이저의 고출력 및 고속 주파수 펄스를 생성합니다. 이는 무엇보다도 열에 민감한 장비 주변의 용도에 도움이 될 수 있습니다. 이 예제는 FLOW-3DAM에서 이 효과를 모델링하는 방법을 보여줍니다. 이 시뮬레이션을 실행하려면 FLOW-3DWELD가 필요합니다.
FLOW-3D@ WELD는 레이저 용접 공정에 대한 정확한 시뮬레이션 기능을 제공하여 최적화된 공정을 개발하게 합니다. 더 나은 공정 제어를 통해 기공, 열 영향 영역을 최소화하고 미세 구조 변화를 제어할 수 있습니다.

Laser Welding
최근에는 뛰어난 생산성과 속도, 낮은 열 입력이 결합되어 기존의 용접 프로세스를 대체하는 레이저 용접 프로세스가 주목 받고 있습니다. 레이저 용접이 제공하는 장점은 용접강도가 좋고, 열 영향 부위가 작으며, 정밀도가 낮고 변형이 적으며, 강철, 알루미늄, 티타늄 및 이종 금속을 포함한 광범위한 금속 및 합금을 용접 할 수 있는 기능이 있습니다.
FLOW-3D@는 레이저 용접 공정에 대한 강력한 통찰력을 제공하고 궁극적으로 프로세스 최적화를 달성하는 데 도움이 됩니다.
보다 나은 프로세스 제어를 통해 기공을 최소화할 수 있습니다. 열 영향부위 및 미세조직을 제어가 가능합니다. FLOW-3D는 자유표면 추적 알고리즘을 통해 매우 복잡한 용접 POOL 시뮬레이션을 해석하는데 매우 적합합니다.
용접 모듈은 레이저 소스에 의해 생성된 Heat flux, 용융 금속에 대한 증발압력, shield gas 효과, 용융 풀의 반동압력 및 다중 레이저 반사와 같은 물리적 모델을 FLOW-3D에 적용하기 위해 개발되었습니다. 키홀 용접과 같은 현실적인 프로세스 시뮬레이션을 위해서는 모든 관련 물리적 현상을 적용하는 것이 중요합니다.
FLOW-3D는 레이저 용접의 conduction and keyhole 방식을 시뮬레이션 할 수 있습니다. 전 세계의 연구원들은 FLOW-3D를 사용하여 용접역학을 분석하고, 공정 매개 변수를 최적화하여 기공을 최소화하며, 레이저 용접공정에서의 dendrite 결정 성장 양상을 예측합니다.

General Motors, Michigan, 중국의 상하이 대학교는 용접 공정 변수, 즉 keyhole 용접에서 기공의 발생에 대해 용접 속도 및 용접 각도와 같은 공정 매개 변수가 미치는 영향을 알아보기 위해 협력하여 연구를 진행하였습니다.
레이저 용접된 Al 접합부 단면의 기공을 분석합니다. Keyhole이 유도 된 기공들은 유동 역학으로 인해 발생되고 균열을 일으킬 수 있습니다. 최적화 공정의 매개변수는 이러한 종류의 기공을 완화할 수 있습니다. FLOW-3D를 사용하여 연구원들은 증발 및 반동 압력, 용융풀, 온도에 따른 표면장력 및 Keyhole내의 다중 레이저 반사, 프레넬 흡수를 포함한 모든 중요한 물리적 현상을 설명했습니다.
연구진은 시뮬레이션 모델을 기반으로 Keyhole 용접에서 생성된 기공들의 주요 원인으로 불안정한 Keyhole을 규정하였습니다. 아래 이미지에서 볼 수 있듯이 뒤쪽 용융 풀의 과도한 재순환은 뒤쪽 용융 풀이 앞쪽 용융 풀 경계를 무너뜨리며 기공들을 생성시킵니다. 갇힌 공간이 증가하는 응고 전면에 의해 갇혔을때 기공들이 발생되었습니다.

When CFD meets laser welding: How sparks fly!
CFD 또는 전산 유체 역학은 수치적 방법을 사용하여 유체 흐름을 연구하는 것입니다. 유체 흐름의 기본 방정식에는 솔루션 해가 없으므로 컴퓨터를 사용하여 방정식을 반복적으로 계산하는 수치해석 방법으로 해결합니다. 일반적으로 CFD 도구는 공기 역학, 엔진 연소, 물 및 환경 흐름, 미세 유체 및 제조 공정에서 광범위한 연구 및 엔지니어링 문제에 적용될 수 있습니다. CFD가 개발에 중요한 역할을 한 기술을 매일 접할 가능성이 있습니다. FLOW-3D 소프트웨어 제품 제조업체인 Flow Science Inc.에서는 자유 표면 흐름 문제 라고하는 특수한 문제 해결에 중점을 둡니다 .
자유 표면 흐름이란 무엇입니까? 밀도 차이가 큰 두 유체간에 인터페이스가 공유되는 분야는 자유 표면 흐름입니다. 예를 들어, 기체-액체 경계면이 제한되지 않고 시간에 따라 자유롭게 움직이고 변경할 수 있다는 점에서 강의 물과 주변 공기 사이에 자유 표면이 존재합니다. FLOW-3D 솔버의 기본 DNA 인 Volume of Fluid 또는 VoF 방법 은 자유 표면의 진화를 추적하는 강력한 계산 기술입니다. 우리는 지난 40 년 동안 이 문제에 거의 전적으로 집중했습니다.
자유 표면 흐름은 제조산업 분야에서도 널리 사용됩니다. 금속 주조에서는 용융 금속과 용융 금속이 채우는 금형 또는 다이의 공기 사이에 자유 표면이 존재합니다. L-PBF ( Laser Powder Bed fusion) 라고하는 적층 제조 공정에서 레이저를 사용하여 분말 입자를 녹이고 융합하여 공정에서 자유 표면 용융 풀을 만듭니다. 그리고 레이저 용접에서는 레이저 빔에 의해 녹아서 두 개의 금속 부품 / 부품을 함께 융합 할 때 형성되는 자유 표면 용융 풀이 있습니다.
이 게시물에서는 레이저 용접 공정에 대한 CFD 시뮬레이션이 유용한 이유를 설명합니다.
레이저 기술은 지난 몇 년 동안 상당히 발전했으며 이제 다른 레이저 제조업체는 다양한 파장에서 펄싱 기능이 있는 고출력 레이저를 제공 할 수 있습니다. 레이저와 로봇 자동화 시스템, 컨트롤러 및 프로세스 센서의 통합은 다양한 제조 산업에서 사용을 확대하여 열 입력이 적고 열 영향 영역이 더 작은 레이저 용접 조인트를 가능하게합니다.
레이저-재료 상호 작용은 복잡하며이를 정확하게 모델링하려면 이러한 시간적 및 공간적 규모와 관련된 물리학을 구현해야합니다. 레이저 열원은 표면에 에너지를 축적하여 기판을 녹이고 용융 금속 풀을 만듭니다. 용융 풀은 전력, 속도 및 스캔 경로와 같은 레이저 가공 매개 변수와 용융 풀의 자유 표면에 동적 증기압을 적용하는 차폐 가스의 영향을 더 많이받습니다. 또한 용접되는 기판의 재료 특성이 중요한 역할을합니다. 용융된 풀의 상 변화와 증발은 용융 풀을 더욱 압박하는 반동 압력을 유발할 수있는 반면 표면 장력은 풀 내의 유체 대류에 영향을줍니다. 키홀 링이있는 경우 레이저 광선이 키홀 내에 갇혀 추가 반사 영향을 받을 수 있습니다. 기판에 더 많은 에너지를 전달합니다. 불안정한 키홀이 붕괴되면 갇힌 공극이 진행되는 응고 경계에 의해 포착되는 다공성 형성으로 이어질 수 있습니다.
분명히 많은 일이 진행되고 있습니다. 이것이 CFD 시뮬레이션이 강력 할 수있는 곳이며 FLOW-3D WELD를 개발할 때 레이저-재료 상호 작용을 이해하는 데 많은 노력을 기울이는 이유입니다. 자유 표면 추적 및 레이저 에너지 증착, 차폐 가스 역학, 상 변화, 반동 압력, 표면 장력, 레이저 광선 추적 및 응고와 함께 유체 및 열 흐름 방정식을 통합하는 물리 기반 모델은 레이저의 복잡한 상호 작용을 캡처하는 데 매우 정확합니다. 용접과정을 해석하는 기능은 용융 풀의 안정성에 대한 다양한 공정 매개 변수의 영향을 분리하고 엔지니어와 연구원이 용접 일정을 최적화하는 데 도움이 될 수 있습니다.
CFD 시뮬레이션은 레이저 용접 프로세스를 분석하고 개선하는데 도움이되는 프레임 워크를 제공 할 수 있습니다. 불안정한 용융 풀은 키홀 유발 다공성, 파열 및 스패 터와 같은 결함을 초래할 수 있기 때문에 용융 풀의 작동 방식을 이해하는 것은 조인트의 품질에 매우 중요합니다. 그 후, FLOW-3D WELD 모델의 출력인 응고된 용융 풀 데이터 및 열 구배와 같은 결과를 미세 구조 또는 유한 요소 분석 모델에 입력하여 각각 결정 성장 및 열 응력 진화를위한 길을 닦을 수 있습니다.
이 게시물이 CFD를 사용하여 레이저 용접 프로세스를 시뮬레이션하는 이점을 이해하는데 도움이 되기를 바랍니다.

우주선 및 자동차 연료 탱크 및 특정 미세 유체 장치는 안전하고 효율적인 작동을 위해 정확한 액체 및 기체 상태 모델링이 필요합니다. 이러한 시스템에 유체 계면이 존재하는 것 외에도, 열 전달 및 상 변화의 물리학도 정확하게 포착해야합니다. 얼마나 복잡합니까!
이러한 복잡한 시나리오를 시뮬레이션하기 위해 FLOW-3D v12.0에는 2 Fluid, 2 Temperature 모델이 도입되었습니다.
단순화 된 모델 : 2 Fluid, 1 Temperature
FLOW-3D 의 인터페이스 추적 방법인TruVOF는 열 전달 및 위상 변화를 포함하여 2 Fluid 모델과 함께 작동합니다. 그러나,이 모델의 단순화 중 하나는, 인터페이스를 갖는 메쉬 셀의 온도가 다음의 개략도에 도시 된 바와 같이 혼합물 온도 (따라서 단순화 된 모델) Tmix로 표현된다는 것입니다.
온도가 경계면을 가로 질러 연속적이고 매끄러 울 때 혼합물 근사치가 적절하지만, 열-물리적 특성의 큰 차이로 인해 액체 및 가스가 있는 경우에는 이를 추정 할 수 없습니다. 이러한 시스템에서 용액의 정확도는 액체-기체 혼합물을 함유하는 셀에서 유체 에너지 및 온도의 평균으로부터 발생하는 과도한 수치 확산에 의해 압도 될 수 있습니다. 단순화 된 온도 슬립 모델은 이러한 경우 부분적인 솔루션만 제공합니다.
단순화 된 모델-2 Fluid, 1 Temperature
종합 모델 : 2 Fluid, 2 Temperature
1 Temperature 접근 방식의 결함을 극복하기 위해 2 Fluid 솔루션에 대한 2 Temperature 모델이 버전 11.3에 도입되었습니다. 여기에는 아래 회로도에 표시된 것처럼 각 유체에 대한 에너지 전달 방정식을 해결하고 각 상의 온도를 저장하는 작업이 포함됩니다. 자유 표면이 있는 메쉬 셀은 이제 액체 (T1)와 가스 (T2) 온도를 모두 나타냅니다.
종합 모델 : 2 유체, 2 온도
탱크 슬로싱(Tank sloshing)
탱크 슬로싱에 대한 이 사례 연구에서, 액체는 초기 온도 300K이고 가스는 400K입니다. 단순화 된 모델과 포괄적인 모델 사이의 수치 확산 정도의 차이는 아래 애니메이션에 나와 있습니다. 온도 윤곽에서 시간이 지남에 따라 용액의 수치 확산은 1 Temperature 접근 방식으로 보여지고 계면 물리를 완전히 가리게 됩니다.
단순화 된 모델 : 2 Fluid, 1 Temperature
종합 모델 : 2 Fluid, 2 Temperature
공기중 드롭 용접(Drop welding in air)
이 낙하 용접 사례 연구에서 액체 금속은 중력 하에서 2300K에서 공기를 통해 고체화 된 금속 베드로 떨어집니다.공기 및 베드 초기 온도는 293K입니다.simplified model에서는 수치 확산으로 인해 액체 금속 낙하 온도가 베드에 도달하기 전에도 급격히 감소하기 시작합니다.반면에 comprehensive model에서는 방울이 초기 온도를 유지하여 훨씬 더 나은 솔루션을 제공합니다.

FLOW-3D의 2 Fluid, 2 Temperature 모델과 유체 인터페이스 추적을 결합하면 사용자는 특히 연료 슬로싱 시스템과 같이 복잡한 열전달 및 위상 변화 문제를 정확하게 모델링 할 수 있습니다.
FLOW-3D는 자유 표면 유체 흐름 시뮬레이션을 전문으로하는 다중 물리 CFD 소프트웨어입니다. 자유 표면의 동적 진화를 추적하는 소프트웨어의 알고리즘인 VOF (Volume of Fluid) 방법은 Flow Science의 설립자인 Tony Hirt 박사가 개척했습니다.
또한 FLOW-3D에는 금속 주조, 잉크젯 인쇄, 레이저 용접 및 적층 제조 (AM)와 같은 광범위한 응용 분야를 시뮬레이션하기위한 물리 모델이 내장되어 있습니다. 적층 제조 시뮬레이션 소프트웨어, 특히 L-PBF (레이저 파우더 베드 융합 공정)의 현상 유지는 열 왜곡, 잔류 응력 및지지 구조 생성과 같은 부분 규모 모델링에 도움이되는 열 기계 시뮬레이션에 초점을 맞추고 있습니다.
유용하지만 용융 풀 역학 및 볼링 및 다공성과 같은 관련 결함에 대한 정보는 일반적으로 이러한 접근 방식의 영역 밖에 있습니다. 용융 풀 내의 유체 흐름, 열 전달 및 표면 장력이 열 구배 및 냉각 속도에 영향을 미치며 이는 다시 미세 구조 진화에 영향을 미친다는 점을 명심하는 것도 중요합니다.
FLOW-3D와 이산 요소법 (DEM) 및 WELD 모듈을 사용하여 분말 및 용융 풀 규모에서 시뮬레이션 할 수 있습니다. 구현되는 관련 물리학에는 점성 흐름, 열 전달, 응고, 상 변화, 반동 압력, 차폐 가스 압력, 표면 장력, 움직이는 물체 및 분말 / 입자 역학이 포함됩니다. 이러한 접근 방식은 합금에 대한 공정을 성공적으로 개발할 수 있게 하고, AM 기계 제조업체와 AM 기술의 최종 사용자 모두에게 관심있는 미세 구조 진화에 대한 통찰력을 제공하는데 도움이 됩니다.
The realm of operations of FLOW-3D
FLOW-3D는 레이저 분말 베드 융합 (L-PBF), 직접 에너지 증착 (DED) 및 바인더 제트 공정으로 확장되는 기능을 가지고 있습니다. FLOW-3D를 사용하면 분말 확산 및 패킹, 레이저 / 입자 상호 작용, 용융 풀 역학, 표면 형태 및 후속 미세 구조 진화를 정확하게 시뮬레이션 할 수 있습니다. 이러한 기능은 FLOW-3D에 고유하며 계산 효율성이 높은 방식으로 달성됩니다.
예를 들어 1.0mm x 0.4mm x 0.3mm 크기의 계산 영역에서 레이저 빔의 단일 트랙을 시뮬레이션하기 위해 레이저 용융 모델은 단 8 개의 물리적 코어에서 약 2 시간이 걸립니다. FLOW-3D는 모든 관련 물리 구현 간의 격차를 해소하는 동시에 업계 및 연구 표준에서 허용하는 시간 프레임으로 결과를 생성합니다. 분말 패킹, 롤러를 통한 파워 확산, 분말의 레이저 용융, 용융 풀 형성 및 응고를 고려하고 다층 분말 베드 융합 공정을 위해 이러한 단계를 순차적으로 반복하여 FLOW-3D에서 전체 AM 공정을 시뮬레이션 할 수 있습니다.
FLOW-3D의 다층 시뮬레이션은 이전에 응고된 층의 열 이력을 저장한다는 점에서 독특하며, 열 전달을 고려하여 이전에 응고된 층에 확산된 새로운 분말 입자 세트에 대해 시뮬레이션이 수행됩니다. 또한, 응고 된 베드의 열 왜곡 및 잔류 응력은 FLOW-3D를 사용하여 평가할 수 있으며, 보다 복잡한 분석을 수행하기 위해 FLOW-3D의 압력 및 온도 데이터를 Abaqus 및 MSC Nastran과 같은 FEA 소프트웨어로 내보낼 수 있습니다.

Fluid dynamics modelling for additive manufacturing
텍스트 또는 HTML 입력
AM프로세스에 CFD를 사용해야하는 이유
AM의 용융 풀(Melt pool) 분해능(0.01 – 0.001mm 길이 스케일)에서 유체 흐름을 정확하게 표현 – 파우더 페드 퍼짐(Powder bed spreading) : DEM(Discrete Element Method)을 통해 파우더 베드 압축 및 흡수 특성을 예측하는데 도움 – 선택적 레이저 용해 : 결함 설계 공간 및 용융 풀(Melt pooe) 형상 매핑 및 예측 – 빠른 응고(Solidification) : 구성 분리 및 위상 핵(Phase nucleation) 형성 및 예측
파우더 증착 및 레이저 용융(Powder deposition and laser melting)
모델 입력 : 파우더 크기 분포, 합금 재료 특성 및 레이저 공정 매개 변수
모델 출력 : 가열/냉각 프로파일, 결함 밀도, 조성 변화
연속 및 펄스 레이저 용융
Takeaway : 두 매개 변수 세트 모두 고밀도 재료를 생산하지만 열 이력(History)은 상당히 다름
모델 정확도 및 검증
NiTi, Ti64 및 316L에서 수행된 모델 검증
용융 풀(Melt pool) 형태 및 키홀링(Keyholing)
공정 공간에서 열분해에 대한 경향

FLOW-3D 는 선박설계, 슬로싱 동역학, 파도에 미치는 영향 및 환기를 포함하여 해안 및 해양 관련 분야에 사용할 수 있는 이상적인 소프트웨어입니다.
자유 표면 유체 역학, 파동 생성, 움직이는 물체, 계선 및 용접 공정과 관련한 FLOW-3D 의 기능은 해양 및 해양 산업에서 CFD 공정을 모델링하는 데 매우 적합한 도구입니다. 해안 응용 분야의 경우 FLOW-3D 해안 응용 분야의 경우 FLOW-3D 는 해안 구조물에 대한 심한 폭풍 및 쓰나미 파동의 세부 사항을 정확하게 예측하고 돌발 홍수 및 중요 구조물 홍수 및 피해 분석에 사용됩니다. 기능은 다음과 같습니다.
자유 표면 – 파동 유체 역학 및 오버 토핑 : 규칙 및 불규칙파 및 파동 스펙트럼 (Pierson Moskowitz, JONSWAP)
Seakeeping – slamming, planing, porpoising 및 선체 선체 변위 : 완전히 결합된 선박 및 수중 차량 유체 역학
선체 – Resistance, stability and dynamics: surging, heaving, pitching and rolling motion (response amplitude operators or RAOs)
슬로싱 – LNG / 밸러스트 탱크
해양 공학 – 파동 에너지 변환기
해안 응용 분야의 경우, FLOW-3D 는 강력한 폭풍과 쓰나미 현상에 의한 해안 구조물이 받는 영향에 대한 세부 사항 예측, 돌발 홍수에 의한 중요한 시설물에 대한 정확한 피해 분석 등을 위해 사용됩니다.
Mooring Lines, Springs and Ropes
FLOW-3D (계류선 및 스프링 등)의 특수 물체를 다른 움직이는 물체에 부착하면 엔지니어가 선박 런칭, 부유 장애물 역학, 부표, 파도에너지 변환기 등을 정확하게 포착할 수 있습니다.
Welding
FLOW-3D 용접 모듈이 추가되면서 조선업계의 용접분야에서는 다공성 등 용접 결함을 최소화할 수 있어 선체의 품질을 크게 높이는 동시에 생산 시간을 최적화할 수 있습니다.
Coastal & Maritime Case Studies
FLOW-3D 사용자들은 연약한 해안선 보호, 구조물에 대한 파장 시뮬레이션, 선체 설계 최적화, 선박 내 환기 연구 등 해안 및 해양 애플리케이션에 FLOW-3D를 사용합니다.
