The results showed that the strength of lap welds is influenced by the weld geometry to a large extent. A three-dimensional quasi-steady state heat conduction model was developed to understand the heat flow mechanism during laser welding of sheet metals of finite thickness. The temperature ...
However, as for fine grain steel, the heataffected zone (HAZ) is softened by welding heat input, and then, the zone of softened HAZ can be the origin of fracture under tensile load. The apparent strength of softened HAZ is affected by the plastic constraint from the surrounding weld metal...
This work outlines the use of an artificial neural network to model the yield and ultimate tensile strengths of weld deposits from their chemical composition, welding conditions and heat treatments. The development of the models is described, as is the confirmation of their metallurgical accuracy....
A106B and 2205 Duplex are the two different pipe materials, 2209 is the weld filler material, and AWSR45 is the buttering layer that is used to control the cracking susceptibility of the welded girth joint. (Butter and buttering refer to the welding of a layer of low strength material, AWS...
Lightweight trend leads to new trend of welding in which optimizing tubes or pipes thicknesses due to its respective workloads. Thinner tube can be used in parts with low working loads and thicker tube for high working loads parts. In order to obtain a good weld, controlling the process para...

In particular, it can be used to join high-strength aerospace aluminum and other metallic alloys that are hard to weld by conventional fusion welding. It was performed on 5mm ... B Manohar - 《International Journal of Research in Engineering & Technology》 被引量: 4发表: 2016年 加载更多...
The effect of the weld solidification mode on tensile properties of the weld metal was investigated. The results showed that the tensile strength of the weld metal of 99.96% and 1050 aluminum was approximately the same as the base metal. On the other hand, the elongation of the weld metal ...
REGRESSION MODELING AND PROCESS ANALYSIS OF RESISTANCE SPOT WELDED JOINTS In this study, the effects of weld current, weld time, electrode force and combination of these on the nugget diameter, heat affected zone and tensile-strength of welding joint in electrical resistance spot welding of AISI 30...
