Abstract
아연도금등의 모재금속보다도 저융점물질이 피복된 재료의 레이저용접은, 맞대여서 할때와 겹쳐지는 이음부분의 경우, 아연의 증발에 의해 접합부가 폭발해서 양호한 용접이 안된다.Laser welding of a material coated with a lower melting point material than that of a base metal such as zinc plating, in the case of joints overlapping with each other in the butt joint, may cause the joint to explode due to evaporation of zinc, thereby preventing good welding.
또, 필러와이어를 용접부에 삽입하면서 시행하는 레이져용접에서도, 용융금속이 제대로 안되어 양호한 용접을 할 수 없다. 자동차 업계에의 레이저용접도입의 최대의 네크였다.In addition, even in laser welding performed while inserting the filler wire into the welding portion, molten metal is not properly formed, and thus good welding cannot be performed. It was the largest neck of laser welding introduction to the automotive industry.
어시스트가스(5)중에 아연을 산화, 연소시키기 위한 산소를 5~30%포함시킴으로써 간단하게 상기 문제의 해결이 된다.The above problem can be easily solved by including 5 to 30% of oxygen for oxidizing and burning zinc in the assist gas 5.
