Abstract

In this study, AISI 410S ferritic stainless steel sheets were joined with laser welding method using different welding parameters. Stressrelieving heat treatment was applied to laser welded joints. Mechanical properties and microstructure of heat treated and non heattreated laser welded joints were investigated. It was determined that grain structure was more coarsened due to heat treatment process and tensile strength decreased because of continuing of decrease in hardness. It was found out that mechanical properties werenegatively affected because of stress relieving heat treatment applied to laser welded joints.

Özet

Bu çalışmada, AISI 410S ferritik paslanmaz çelik levhalar farklı kaynak parametreleri kullanılarak lazer kaynağı ile birleştirilmiştir.Lazer kaynaklı birleştirmelere kaynak sonrası gerilme giderme ısıl işlemi uygulanmıştır. Isıl işlemli ve ısıl işlemsiz lazer kaynaklıbirleştirmelerin mekanik özellikleri ve mikroyapıları karakterize edilmiştir. Kaynak sonrası uygulanan ısıl işlem nedeniyle taneyapısının daha da kabalaştığı, sertlik düşüşünün devam etmesiyle birlikte çekme dayanımında da düşüş meydana geldiğibelirlenmiştir. Kaynak sonrası uygulanan ısıl işlem sebebiyle mekanik özelliklerin olumsuz etkilendiği sonucuna varılmıştır.
