Euro-6 norms for reduction of CO2 emissions and ECE-R66-01 regulation safer passenger transportation became legislative obligations bus builders. These two adaptations increase the weight a as nearly 600kg which also increases fuel consumption 1.5-3%. Dual phase (DP) steels can compensate these by decreasing thickness components. Because, ferrite provides steel with good formability martensite ...

A gap is generated in the weld joint due to dimensional error of welded parts and thermal deformation aluminum alloy’s gas metal arc welding (GMAW) process alloy. The optimum conditions corresponding different gaps are required field. In this study, were optimized using Taguchi’s design experiment method response gaps. Al5083-O with a thickness 4.0 mm was used as base material, GMAW performed o...

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...
