Abstract
The effects of submerged-arc welding consumables, wire and flux, on solidification cracking in the weld metal of medium-carbon steel were investigated. It showed that weld metal with a greater amount of C, S, and P had a wider brittleness temperature range, BTR, which resulted in longer total and maximum crack..... More

Abstract
A new aluminum welding wire with 0.8 wt% higher in Mg content was developed and compared with commercial welding wire of the 5000 series. The weldability of the Al5083 base material was evaluated using high current metal inert gas (MIG) welding, using the developed Al5183 and commercial Al5183 welding wire...... More

Abstract
Austenitic stainless steels have excellent mechanical property and corrosion resistance, and are for these reasons used in demanding applications such as power plant, nuclear reactor and off-shore plant. Especially, austenitic stainless steel 304 (STS304) is mainly used as a pipe material in nuclear power plants. Submerged arc welding (SAW) is..... More

Abstract
Aluminum conductors are increasingly replacing copper because Al has lower cost and lighter weight, and consequently the demand for Al-Cu joints for industrial applications is growing. However, an intermetallic compound is known to grow at the Al-Cu interface, and will result in fracture if it grows above a critical thickness...... More

Abstract
The effects of nitrogen content on the HAZ softening of Ti-containing high strength steels manufactured by accelerating cooling were investigated and interpreted in terms of the microstructures in the softening zone. Regardless of their content, all of the steels investigated showed a softened zone 9-10 mm wide. The minimum hardness..... More

Abstract
The deformation and failure behaviors of dissimilar metal joints between SS400 steel and STS316L steel were investigated. The dissimilar metal joints were fabricated using the tungsten inert gas (TIG) welding process with STS309 steel as a filler metal. The microstructures of the dissimilar metal joints were investigated using an optical..... More
