Online Monitoring and Control of Butt-Welded Joint Penetration during GMAW
نویسندگان
چکیده
Butt welding is an important link to ensure quality, and the penetration state of weld main criterion achieve this. Online monitoring control welded joints measure quality. The molten pool image monitored by a visual sensor in gas metal arc (GMAW) process, bottom width predicted regression network model. Combined with real-time method, current changed monitor real time. Butt-welding experiments different groove angles verified that proposed method could satisfactory accuracy generalization ability. For butt-welding constant 30° 45°, MAE controlled backside melt target values was 0.2603 mm 0.2620 mm. Therefore, it provides feasible for online penetration.

Stress Intensity Factor Expression for Welded Butt Joint with Undercut and Inclined Lack of Penetration Defects considering the Effect of Joint Shape
In this paper, the stress intensity factor (SIF) expression for defected butt welds containing undercut and inclined lack of penetration (LOP) subject to far-field tensile stress is derived. Some of the standards such as ISO 5817 and BS EN 25817 have specified allowable limits for the length of the undercut and LOP defects and for the height of the weld. In addition, EN 29692 standard has deter...

متن کاملResidual Stresses in Butt and Socket Welded Joints
A finite element scheme for simulation of welding residual stresses is presented in this paper. Detailed thermal and residual stress analyses for butt-welded and socket-welded pipes are performed using ANSYS and ABAQUS. The calculated distribution of axial stress and hoop stress at welded joint are validated against experimental results. Furthermore, residual stress relaxation under high amplit...
