In this study, AISI 410S ferritic stainless steel sheets were joined with laser welding method using different welding parameters. Stress relieving heat treatment was applied to laser welded joints. Mechanical properties and microstructure of heat treated and non heat treated 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 were negatively affected because of stress relieving heat treatment applied to laser welded joints.

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 kaynaklı birleştirmelerin mekanik özellikleri ve mikroyapı incelemeleri karakterize edilmiştir. Kaynak sonrası uygulanan ısıl işlem nedeniyle tane yapısının daha da kabalaştığı, sertlik düşüşünün devam etmesiyle birlikte çekme dayanımında da düşüş meydana geldiği belirlenmiştir. Kaynak sonrası uygulanan ısıl işlem sebebiyle mekanik dayanımın olumsuz etkilendiği sonucuna varılmıştır.
