Mechanical and microstructural investigation of dissimilar joints of Al-Cu and Cu-Al metals using nanosecond laser

An optimization model for monthly time-step drilling schedule under planned field production

“…However, for China, which lacks oil and gas resources, planned drilling to meet the country's demand for oil and gas resources takes precedence over achieving economic benefits. One of the pivotal steps of the field plan is to finalize the drilling schedule [ 5 ], determining the timing and the relevant number of drillings—specifically, how many wells should be drilled in a given month [ 6 ].…”

Study on Morphology, Microstructure and Properties of 6063-T6 Aluminum Alloy Joints in MIG Welding

“…It has the advantages of high strength, reliability in processing, corrosion resistance and good heat treatment properties, and is widely used in various fields such as aerospace, automotive engineering, construction, marine engineering, electronics and transportation [ 1 , 2 , 3 , 4 , 5 ]. Aluminum alloys are lightweight and inexpensive, and are widely used in the manufacture of structural parts for automobiles to achieve light weight [ 6 ]. MIG welding is a welding method that uses inert gas to protect the weld metal from contamination.…”
