Real-time monitoring of laser welding of galvanized high strength steel in lap joint configuration
Two different cases regarding the zinc coating at the lap joint faying surface are selected for studying the influence of zinc vapor on the keyhole dynamics of the weld pool and the final welding quality. One case has the zinc coating fully removed at the faying surface; while the other case retains the zinc coating on the faying surface. It is found that removal of the zinc coating at the fayi...
متن کاملMicrostructure Evolution and Shaping of Friction Stir Lap Welded Dissimilar Magnesium Alloy Joint
Friction stir lap welding (FSLW) experiment has been conducted on 3mm thick AZ80 extruded sheet and 2.3mm thick AZ31B rolled sheet. The influence of the shape of the taper thread mixing head on microstructure has been discussed. Pores forming, hooked defects, interface migration, tissue distribution have been analyzed. The organization of both sides of nugget zone (NZ) is arranged diagonally ab...
متن کاملLaser Welded versus Resistance Spot Welded Bone Implants: Analysis of the Thermal Increase and Strength
INTRODUCTION The first aim of this "ex vivo split mouth" study was to compare the thermal elevation during the welding process of titanium bars to titanium implants inserted in pig jaws by a thermal camera and two thermocouples. The second aim was to compare the strength of the joints by a traction test with a dynamometer. MATERIALS AND METHODS Six pigs' jaws were used and three implants were...
متن کاملNon Destructive Testing of Laser Welded Lap Seams by Eddy Current Technique
Eddy current method has been tested for detection and classification of defects in laser welded seams. Influence of disturbance effects was investigated systematically. Before analysis data have been processed for consideration of changes in material properties. It can be shown that seam different defects lead to different characteristic indication ranges in the impedance plane. By investigatio...
متن کاملAnalysis of Cracks in the Pulsed Nd:YAG Laser Welded Joint of Nickel-Based Superalloy
The weldability of GTD-111 nickel-based superalloy by pulsed Nd:YAG laser welding with an average power of 250 W was studied, and the microstructural evolution and cracking characteristics were also investigated. The solidification cracking of the fusion zone (FZ) and the intergranular liquation cracking in the heat affected zone (HAZ) were observed in the joint. Solidification cracking was cau...
