“…Another way for obtaining better properties, especially in microstructure, is to input various elements into the puddle to improve hardness, toughness, penetration, and other properties of weld [2][3][4]. In this way, typical materials, micro-particles, and nanoparticles can be used [5][6][7][8]. It has been shown that in the SAW process, hardness decreases by adding TiO 2 nanoparticles to the weld pool [9].…”

One of the most important weld quality characteristics related to the strength of the weld is the hardness of melted zone (HMZ) that is affected by different input parameters in the submerged arc welding process. In recent years, expensive nanomaterials have been effectively used in improving the quality of products in various fields. Keeping this in mind, it was therefore, decided to use a cost-effective approach to extract expensive and poisonous vanadium, from the hazardous wastewater collected from the Bistoon thermal power plant in Kermanshah province in Iran, and then introduce it into the weld pool via the cheap boehmite nanoparticles to investigate its impact on the HMZ. A five-level five-factor rotatable central composite design was then employed for collecting data in modeling of the HMZ as a function of arc voltage (V), welding current (I), stick-out (N), welding speed (S), and thickness of boehmite nanoparticles surface adsorbed with vanadium (F) coated on low-carbon steel plates (St37) prior to actual welding. The results showed that the addition of boehmite nanoparticles surface adsorbed with vanadium increased the HMZ by 13 % approximately.

The using of nanotechnology in the welding process has great importance in developing the mechanical properties of welding joints for metals. This paper investigated the effect of addition TiO 2 NPs to welding joints to improving the Impact toughness property of the welding joints. The cold spray coating method of the nanoparticles are used to adding the TiO 2 NPs to the welding joints during the welding process. Three weight fraction are used for TiO 2 NPs (0.75%, 1.5%, and 2%). The testing samples were prepared for Impact test, and microstructure by SEM. The results show the increasing in Impact toughness of welded joints with an increase of TiO 2 NPs concentrations. The average Impact toughness for the welded sample without TiO 2 NPs. was (162.4 J), while the average Impact toughness for the welded sample with (1.5)% TiO 2 NPs. was (231.2 J) with improving rate of (42.36%). The Microstructure images by SEM show the adding of TiO 2 NPs decreases the grain size and homogenous region in welded joints cross-section compared with a sample without adding TiO 2 NPs. The EDS analysis show that increase Ti contain and decrease (Mn and Si) contain with increase TiO 2 NPs.
