Abstract

Stainless steel SS304 is one of the most widely employed steel alloys used in a wide variety of industries. However, under certain atmospheric and environmental conditions, it is likely to corrode. High humidity can cause damage to the native chromium oxide layer, causing rust formation. Once the corrosion develops, it becomes difficult to remove the rust layer locally and chemically treated or dry blasted. But recently, a novel application of laser surface irradiation can be employed to remove the corrosion products formed on the surface rapidly and robustly. The laser corrosion removal process is a non-mechanical technique that can remove rust from difficult-to-reach areas with high efficiency. However, the rust removal depends on the laser de-rusting process parameters. This work studies the effect of laser corrosion removal parameters such as power, frequency, and several loops with an optical microscope to observe surface features. Results indicate that the number of loops is a significant parameter that enhances corrosion removal significantly. Additionally, the selection of correct frequency, power and scanning speed, and hatching distance also play a significant role in corrosion removal efficiency. Using a low-power fiber laser marking machine to remove corrosion from metal samples will provide energy savings for the commercialization of such a process.

Abstract

Laser micro-welding is being widely used in many industries because of its speed and precision. This study's Stainless Steel (SS304) and Duplex Stainless Steel (DSS 2205) possess good ductility and strength. However, laser micro-welding is a challenge for joining dissimilar materials. Pulse wave mode micro-welding was employed in this study. The parameters that were varied throughout the study were the peak power and hatching distance. With that being so, the other parameters such as frequency, pulse width, mark loop and welding speed were kept constant. After preliminary tests were carried out, a range of parameters was obtained by knowing the threshold value to obtain a proper joint. The welded specimens were analyzed by conducting weld geometrical properties analysis, failure analysis with the aid of image analysis software (Image J), and surface color examination. The strongest tensile strength value obtained was 13.56 MPa with a weld width of 0.611mm, whereas the least tensile strength value was 0.8 MPa with a weld width of 0.577mm. A percentage difference of 177.015% between the highest and lowest tensile stress value was observed. The highest distortion lies with specimen I (power 95%, hatching distance 0.001mm) with an angular deviation of 5.013◦ on the left side and 4.086◦ on the right concerning the horizontal place. It was concluded that too high power caused distortion, thereby resulting in a poor joint.

Abstract

The difficulty in drilling arises due to unexpected and surprising behavior of rocks which leads to waste of time, cost, material and sometimes whole borehole. The logging becomes difficult to perform and to investigate due to drilling issues such as borehole instability, lost circulation stuck pipe and under gauge holes. This study sheds light on the state of art of drilling problems, affiliated issues and causes along with their best possible prediction, prevention and solution methodologies. The well schedule, weekly drilling report, construction document, and different well documents were thoroughly inspected. This study incorporates the benefits of statistical analysis of 20 wells, including lateral longitudinal and vertical, as well as how effective constitutive modeling is for classifying well-bore instability triggers and forecasting safe mud-weight windows. The detection models discussed encourages superior comprehension of the fundamental material science standards, and gives improved situational consciousness of drilling problems’ occurrences.
