Influences of welding parameters on distortion
International Journal of Microstructure and Materials Properties, 2010Laser beam welding (LBW) is an established serial process in manufacturing of parts for aircraft industries, which is characterised by the advantages of weight reduction and shortened process time compared to conventional riveting techniques. However distortions can occur after LBW. Depending on the intensity the distortions impair, e.g., assembly work

Welding residual stress and distortion
1992A characteristic of application-oriented analysis of welding residual stress and distortion is the mainly decoupled representation of the thermal, mechanical and microstructural processes (illustrated by the line arrows in Fig. 3). The basis of stress and distortion analysis is the temperature field during welding, determined numerically or by ...

Numerical Methods to Predict Distortion in Welded Components
Volume 6: Materials and Fabrication, Parts A and B, 2008Numerical methods have been established to simulate welding processes. Of particular interest is the ability to predict residual stress fields. These fields are often used in support of structural integrity assessments where they have the potential, when accurately characterised, to offer significantly less conservative predictions of residual profiles

Distortion control in welded structure with Advanced Submerged Arc Welding
Materials Today: Proceedings, 2020Abstract Weld induced distortion is often the most challenging problem in the manufacturing industry. When distortion exceeds a safe limit in the welded structure, misalignment of parts occurs, which generally requires costly corrective measures such as cold bending and flame straightening to lower the distortion to an acceptable limit, which also ...

Welding Residual Stress and Distortion
2016The panels, subassemblies and assemblies being welded are subjected to thermal cycles of heating followed by cooling. It causes shrinkage forces to develop in the welded panels. The shrinkage forces tend to cause different degrees of distortion.

Tandem Gas Metal Arc Welding for Low Distortion Butt Welds
Advanced Materials Research, 2011The feasibility of using Tandem Gas Metal Arc Welding (T-GMAW) to produce full penetration butt welds in 5mm ship panel steel plates has been assessed and compared to the current Submerged Arc Welding (SAW) process. Experiments conducted show that the T-GMAW process is feasible and demonstrated a significant improvement over the SAW process in several ...

Effect of Transformation Temperature of Weld Metal on Welding Distortion
Volume 5: Materials Technology; CFD and VIV, 2008Welding distortion during welding is an inevitable outcome of weld metal shrinkage due to non-uniform heating and cooling in welded joints. Several studies have investigated methods of estimating and controlling welding distortion in order to construct steel structures correctly, easily and efficiently.

Hybrid Induction Arc Welding Reduces Weld Distortion and Boosts Productivity
AM&P Technical Articles, 2015Abstract A new welding process known as hybrid induction arc welding (HIAW) or high deposition arc welding (HiDep) uses a hybrid approach to reduce—or even eliminate—weld distortion and greatly increase productivity. Operating directly in front of the arc welding torch, a portable induction coil heats the surfaces of the weld to, or near,

ANGULAR DISTORTION IN BUTT ARC WELDING
2018The importance of fusion weldingtechnology has been widely recognized in the manufacturing process of varioussteel structures such as ships, bridges, construction machines, power plants,and automobiles. However, a significant disadvantage of fusion welding is thatit often generates unacceptable levels of geometric imperfections such asshrinkage and ...
