Radiographic and Ultrasonic Inspection of Duplex and Austenitic Stainless Steels Weld Defects that Formed After TIG Welding
Abstract
Duplex stainless steels maintains superior corrosion
resistance especially in chlorine containing media besides they exhibit
satisfactory strength values that close to the structural steels. The
austenitic stainless steels that supports exact resistance to oxidation are
also selected intensively upon their high temperature resistivity are
economical choice rather to duplex types.
In
this study; AISI 304L and S32205 stainless steel plates are TIG welded by
ER312, ER316 and ER2209 coded TIG welding wires for composing three different
weld metal contents and discontunities of weld metal regions are investigated
by both ultrasonic and radiographic incpection. Discotunities in weld regions
are determined by an alternative and cheaper ultrasonic inspection rather than
expensive radiographic technique.

Dubleks ve Östenitik Paslanmaz Çeliklerin TIG Kaynağı Sonrasında Oluşabilecek Kaynak Hatalarının Ultrasonik ve Radyografik Muayene Yöntemleri ile İncelenmesi
Abstract
Dubleks
paslanmaz çelikler özellikle klor içeren ortamlarda korozyona karşı üstün
dayanım sağlarken aynı zamanda yapı çeliklerine yakın değerlerde tatminkâr
mukavemet sağlamaktadırlar. Oksitleyici ortamlarda korozyona tam dayanım
sağlayan, yüksek sıcaklıklarda kullanımda yoğunlukla tercih edilen östenitik
paslanmaz çelikler ise dubleks paslanmaz çeliklere kıyasla daha ekonomik bir
satın alma maliyeti sergilemektedirler.
Bu çalışmada; AISI 304L
ve S32205 paslanmaz çelik levhalarının aynı koşullarda TIG kaynağı sonrasında
üç farklı kimyasal bileşime sahip olan; ER 2209, ER 312 ve ER 316 kodlu TIG
telleri ile üç farklı kaynak metali içeriği oluşturulmaya çalışılmış,
ultrasonik ve radyografik muayene yöntemlerinin her ikisi ile kaynak metalinin
süreksizlikleri incelenmiştir. Test maliyeti daha yüksek olan radyografik
muayene yöntemine alternatif olarak ultrasonik muayene yöntemi ile muhtemel
kaynak bölgesi süreksizliklerinin daha düşük maliyetle tespit edilebileceği
belirlenmiştir.
