The paper investigates the quality of a steel welded joint tire shredding knife. Defects occurring during restoration are analyzed. In order to determine mechanical properties joint, following tests and were carried out: visual inspection, magnetic particle tests, metal hardness chemical analysis parent weld metal.

A high temperature measurement system for creep deformation based on the digital image correlation (DIC) technique is described. The new system is applied to study the behaviour of a multi-pass welded joint in a high temperature tensile test and a load controlled creep test at 545°C. Spatially resolved tensile properties and time dependent creep deformation properties across a thick section typ...

Welded mild steel is used in different applications engineering. To strengthen the joint, weld can be reinforced by adding titanium alloy powder to joint. This results formation of incomplete martensite a welded The affects mechanical properties. Therefore, this study aims predict volume fraction butt joints understand complex phenomena during microstructure formation. do so, combination finite...

Widely used in dentistry, Ti-6Al-4V alloy is difficult to cast and solder, as it frequently exhibits pores inside the structure. This study was conducted to evaluate the effect of joint openings and diameters of laser-welded joints executed in Ti-6Al-4V structures on the presence of pores as checked by radiographic procedures. Sixty dumbbell rods with central diameters of 1.5, 2.0 and 3.5 mm we...

In this study, a three-dimensional (3D)finite elementmodel is developed to investigate thermally induced stress field during hybrid laser–gas tungsten arc welding (GTAW) process. In the hybridwelding case, we focus on the GTAWprocess sharing commonmolten poolwith laser beam and playing an augment role in thehybridweldingsystem.Anexperiment-based thermalanalysis isperformedtoobtain the temperatu...

This paper discusses the localized eigenstrain method, a new technique for the determination of triaxial residual stresses deep within long welded joints. The technique follows from the “Inherent Strain Method” developed by Ueda, which uses a combined experimental and analytical approach to determine the source of residual stress (i.e., “eigenstrain” or, equivalently, “inherent strain”) by sect...

Adhesive joining is recognized as a potential enabling technology for a variety of material systems being considered in automotive structures where traditional fastening methods would be inappropriate. Well known examples include fiber reinforced composites and polymers. Additionally in certain circumstances, adhesive bonding of steel structures can provide benefits such as improved stiffness a...
