There are a wide range of important applications for metal tube materials in various fields. The production process of high-frequency longitudinally welded pipe includes first using a roller to coil the long steel strips of a certain size into a cylinder shape, and then join them by heating the steel materials at the welding edge with a high-frequency welding machine — Fig. 1. The processes inc...
The objective of this research is to develop an experimental-theoretical analysis about the 11 influence of the cooling medium and the geometry of the welding bead profile in fatigue life and 12 associated parameters with structural integrity of welded joints. A welded joint with cruciform 13 geometry is considered using SMAW, plates in structural steel ASTM A36 HR of 8 mm of 14 thickness and E...
In this study, corrosion behavior of Ti-6Al-4V titanium alloy joint by friction stir welding with a rotational speed of 375 rpm and a travel speed of 100 mm/min was investigated. The welding procedure was carried out under β-transus temperature that was consisted of equiaxed grains in the stir zone. The corrosion behavior of the welded joint was investigated in 3.5% NaCl solution at temperature...
Conventional fusion welding of aluminum alloys results in coarse-grained structure, inevitable defects, and significant softening in the welding region. Friction stir welding with bobbin tool is a technique of friction stir welding method that has a great potential for developing applications of friction stir welding method in marine, aerospace, and automotive industries due to having an extra ...

(57) ABSTRACT Metallic materials may be joined utilizing a friction stir processing teclmique. The friction stir processing technique utilizes a shaped, rotating tool to move material from one side of the joint to be welded to the other without liquefying the base material.
Resistance Spot Welding (RSW) is one of the effective manufacturing processes used widely for joining sheet metals. Prediction of weld strength of welded samples has great importance in manufacturing and different methods are used by researchers to find the fracture force. In this article, the Adaptive Neuro-Fuzzy Inference System (ANFIS) is utilized for prediction of joint strength in welded s...
