corpus id:50376735. weld quality analysis of tig, laser and electron beam welded ss 304 and 316 materials with ndt techniques @inproceedings{kumar2011weldqa, title={weld quality analysis of tig, laser and electron beam welded ss 304 and 316 materials with ndt techniques}, author={b. r. "Hybrid Laser/arc Welding of Difficult-to-Weld Thick Steel Addressing the above issues, a feasibility study of hybrid laser/arc welding of 8-mm-thick HSQTS in butt and T-joint configurations was conducted experimentally and numerically. This chapter focused on developing the processing parameters to produce a sound full-penetrated weld in a single pass.

A Study on the Algorithm of Quality Evaluation for Fiber

Dec 09, 2020 · PSC distributions according to upper hardness in ber laser welding. This stabilization of the upper hardness is because if the data trend falls below 132.2, a drift that can predict the weld hardness is found, and if it is less than 140, the distribution of the upper hardness is randomly distributed and no association is identied. A Study on the Algorithm of Quality Evaluation for Fiber Dec 09, 2020 · This welding experiment was performed to check the quality of the laser welding part of A553-1 steel and to identify optimal process parameters. For the experiment, a 5 kW class ber laser welding machine (Miyachi ML-6950A model, Amada Weld Tech Co. Ltd., Chiba, Japan) was used and the A Study on the Welding Characteristics of Tailor Welded Lehigh University Lehigh Preserve Theses and Dissertations 2012 A Study on the Welding Characteristics of Tailor Welded Blank Metal Sheets Using GTAW and Laser Welding PORNSAK THASANARAPHAN Lehigh University Follow this and additional works at:This Dissertation is brought to you for free and open access by Lehigh Preserve.

Effects of laser focusing properties on weldability in

In this work, high-power fiber laser welding of a 12-mm-thick high-strength steel plate was performed with two optics systems with different focusing properties to investigate weldability and behavior of the molten pool and keyhole during laser welding. The effects of laser focusing properties on weld defects, such as underfill, humps, spatter, and porosity, and on penetration depth were Fracture mechanism on Al-Li alloy T-joint welded by dual Dual laser-beam bilateral synchronous welding technique is considered to replace riveting in terms of skinstringer joints. The 2.0-mm thick Al-Li alloy T-joint, which is welded by dual laser-beam Investigation on weldability of magnesium alloy thin that in laser welding process due to the larger heat input (95 Jmm1). 3.1.3 LaserGTA hybrid weldability of T-joints LaserGTA hybrid welding is suitable to weld T-joints because it can overcome some of the shortcomings of both laser welding and GTAwelding. The laser power P keeps at 300 Wand the arc current I keeps at 100 A so that the

Laser Beam Welding of ium

However, higher-power lasers, which have deeper penetration capabilities, have opened the way for the use of lasers to weld thicker Research of Laser Beam Welding of Inconel Alloy Study of weld joints of nonferrous, Inconel 625 alloy sheets using a new generation disk laser as the green welding technology for the effective manufacturing were carried out, and the results are presented in this paper. Weld joints of the Inconel 625 alloy sheets 2,0 mm thick were welded by laser without an additional material at a flat position, using a high purity argon as the shielding gas. Steel Sheets Laser Lap Joint WeldingProcess AnalysisNonconventional joining methods, such as laser welding in butt, lap and T-joint configurations, are also being widely studied [10,11,12,13,14]. Numerical analysis of the laser welding process has been undertaken, including lap joints, for a wide range of materials by many researchers [15,16,17,18].

Study on Pulsed Nd:YAG Laser Butt Welding of High

The maximum hardness resulted in the 630 stainless steel region and the minimum hardness occurred for the 321 stainless steel region. This was inferred from the micro hardness test. [2] Pulsed Nd:YAG laser welding of AISI 304 to AISI 420 stainless steels Pulse Duration (s):0.2 Scan speed:300 mm/min stainless steel Thickness =0.8mm Avg Power (W)=100 Technology qualification of laser(-hybrid) welding of Hybrid laser-arc welding is a process in which the laser beam and the arc are combined in one process zone Sokolov, M., et al., Laser welding and weld hardness analysis of thick section S355 structural steel. Materials & Design, 2011. 32(10):p. 5127-5131. Weld Quality in Aluminium Alloys - DiVA portalline in 5 mm thick plate. The microstructure evaluation has shown that the grain size in the HAZ has been influenced while welding. The EDS analysis shows that a small amount of AlFeSi particles occur in the base material and HAZ but not in the weld seam. Future research is suggested to focus on understanding more about ageing, coarsening
