to examine the influence of welding speed and power on weld bead geometry and performance parameters such as duty cycle‚ pulse overlap‚ energy density and bead diameter. In this contest‚ first experiment is conducted on austenitic 304L stainless steel sheet by varying the welding speed from 2 mm/s to10 mm/s and second experiment is conducted varying laser power from 300 W to 3500 W. It was found from the experimental and analytical approach welding speed and laser power significantly affects on

Introduction of Research Steel-reinforced concrete is a widely used structural material. The effectiveness of the steel reinforcement depends on the bond between the steel reinforcing bar and the concrete. Reinforced concrete is a composite material in which concrete ’s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength and ductility. The reinforcement is usually‚ though not necessarily‚ steel reinforcing bars and is usually

Chapter 3‚ goes into how the missionaries tried to help blacks after the civil war. The missionaries‚ however‚ had more enthusiasm than they did knowledge. When a poet was asked to describe each race he described the whites as tribe chiefs‚ red people were proud warriors‚ the yellow people were princes‚ and the black people were savages with rings in their noses.

This chapter opens up with the mysterious Phaistos disk that was found by archaeologists on the island of Crete in 1908 and its interesting technological aspects. Many inventions were made not for need but for mere curiosity and hobby. Diamond makes two main conclusions about technology is that it develops cumulatively and that most technology seems to have been invented for curiosity‚ therefore its uses are developed after it is made. To determine if an invention will be accepted there are four
