Abstract

Welding large structures often requires alternating welding on both sides, which is time-consuming and costly. To overcome this, the media backing ceramics are used as hot melt barriers to form better results, speed up the ship welding process and reduce budgets. This study aims to determine the effect of media use baking ceramics against tensile strength test on ASTM A36 steel by SMAW welding. The calculation results show a strong effect on ASTM A36 steel. MarkYield strength is the highest found in specimens that do not use baking ceramics, equal to 322.413Mpa, while the valueYield strength is the lowest found in testing that uses baking ceramics at 309.92 Mpa.

Abstract

Welding is a job with a high risk of danger for the welder, such as a hot working environment, dehydration, eye complaints, and uncomfortable working positions. One of the conditions that often occur in welding workers when carrying out work is the position of the welder's body when carrying out welding, which is required to stand. This condition will cause complaints that the welder feels because carrying out the welding process takes a long time. This causes the welder to experience pain in the legs and back and, if done continuously, will trigger long-term illness. The method used in this research is method Rapid Entire Body Assessment (REBA). From the results of manually calculating the REBA method, a score of 2 is obtained, which can be interpreted according to the REBA Classification and Risk Level as low risk. Based on the results of work posture testing on the welding section, the workload of the workers has been reduced from 5 to 2. Therefore, the best position is welding while standing with the body upright; this will help the welder work without injury and has been tested using the REBA method.

Abstract

Welding combines two or more materials, especially metals, using heat or pressure. Welding is important in various industries, such as automotive, construction, manufacturing, and aerospace. This study aims to analyze trends and developments in welding technology in the future based on the latest data and sources. The research method used is trend analysis, which identifies patterns or directions of change of a variable or phenomenon based on historical data or predictions. The data was collected from web search results. The data is analyzed by classifying based on the type of welding. These factors influence the development of welding, new technologies related to welding, and the challenges and opportunities faced by the welding industry. The research results show that various factors, such as industrial needs, technological advances, environmental issues, and government regulations, influence the development of welding in the future. Some examples of welding technologies that will develop in the future are the use of robotics and artificial intelligence to automate the welding process and improve accuracy and safety, the development of Friction stir welding techniques to combine metals that are difficult to weld, such as aluminium, magnesium, copper, and titanium, and the application of hybrid welding techniques that combine two or more types of welding to obtain optimal results, such as laser-arc welding or laser-friction welding. This research also discusses the social and economic impacts of future developments in welding, especially related to job availability, labour skills, and community welfare. In addition, this study provides suggestions for further research or for welding industry practitioners, such as conducting further research on the environmental impact of future welding developments, developing welding technologies that are environmentally friendly, energy-efficient and sustainable, and improving cooperation between related parties in the welding industry.

Abstract

Subsea pipe installations are installed on the seabed with a particular security system so that the pipes will not shift from their location due to wave pressure, tidal currents and ground movements. The underwater pipes are installed so that they follow the seabed's contour with an installed length of tens of kilometres, which routinely carries feed intake and other process materials. Hence, the existence of this underwater pipe is essential. Some of the problems faced in underwater pipes include damage to underwater pipes due to shifting and kinking, pipes hitting ship anchors, and pipes being dragged by ship anchors so that they are damaged and broken. This incident resulted in disruption and cessation of company operations. This problem requires further investigation to find out the factors and causes of the incident in order to find an effective solution. Articulated Concrete Block Mattresses (ACBM) are artificial concrete blocks in a rectangular shape which will be installed regularly on underwater pipes (SPL) and between one block and another concrete block connected with polypropylene ropes. ACM adjusts its geometry to suit the structure and adapts to undulations in the river/seabed (e.g. due to scouring). From the description of the research results and discussion of the research results, several things can be concluded as follows: The hydrodynamic coefficient of the ACBM can be obtained using an experimental test process, namely the direct pull test, which will produce coefficient values ​​that need to be validated by predicting the cell strength load and crisis speed with maximum error agreement. by 8.3% in five varied tests. Moreover, it was obtained using a numerical study that simulates pipes protected with ACBM in two conditions: regular waves in deep water and breaking waves in shallow water. Moreover, these two studies concluded that the drag and lift coefficients on pipes protected with ACBM were smaller than those on pipes that were not protected.

Abstract

The oil and gas exploration and production industry significantly contributes to the global economy, and undersea pipelines are the safest and most economical route to transport natural gas and crude oil from offshore to land. However, undersea pipeline networks are prone to leaks that can cause financial losses and extreme environmental pollution. Therefore, it is essential to monitor pipelines to detect leaks promptly or even predict leaks to reduce the impact of oil spills on society. Various leak detection methods have been developed, and further research is needed to identify research gaps for future work. There are various methods for detecting pipe leaks, each with advantages and disadvantages. External-based methods tend to be more accurate in finding leaks, while internal/computational methods can determine the level of leaks. The acoustic method is considered the most efficient for inspecting subsea pipelines and detecting leaks. However, each method has strengths and limitations that must be considered before choosing the proper method. Advances in computing technology have also enabled the use of dynamic modeling approaches more popular in the oil and gas industry. Factors such as cost, sensitivity, accuracy, ease of use, and the type and location of the pipeline also need to be considered in selecting a suitable pipeline leak detection method.
