Abstract

In the welding process, it is not uncommon for a defect or discontinuity to occur in the welding results. Common defects on the surface are undercut, concavity, incomplete penetration, spatter, burn-through, and mismatch. While defects in internal welds that are often found during testing are porosity, worm holes, slag inclusions, incomplete fusion, and cracks, To obtain pipeline results that comply with the specifications set by the welding engineer and ASME or ASTM standards, it is necessary to test surface cracks and inside cracks using the non-destructive test (NDT) method, namely the dye penetrant test and radiography test, to determine the results of welding at pipe joints. In addition, it is also necessary to know the time and cost required for each method in the testing process. The results of the radiography test and penetrant test on carbon steel pipe welding joints showed porosity welding defects 1 mm long. Weld defects in duplex stainless steel pipes were not found. Then the results of the total testing time using the radiography test take 18% longer than testing using the penetrant test. Furthermore, the total costs that need to be incurred during the test are found to be 2~3 times more expensive than the cost of the penetrant test.

Abstract

The rapid development of science and technology provides convenience in the industrial world, such as increasing work productivity and the number of workers. However, the development of technology has problems, one of which is the problem of occupational safety and health which can cause harm to workers and companies. Often, welders neglect personal protective equipment, which can result in work accidents when welding. Therefore, this research was conducted to determine the relationship between occupational accidents and OSH knowledge, OSH training, and the use of personal protective equipment in the welding process. The method used is univariate and bivariate analysis. The results showed a significant relationship between K3 knowledge and occupational accidents in the welding process (sig. 0.001 <0.005). At the same time, there was no significant relationship between K3 training (sig. 0.235 value > 0.005) and the use of PPE (sig. 0.187 > 0.005) with work accidents in the welding process.

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

Welding is a metal joining process by melting some base and filler metals. SMAW welding (Shielded Metal Arc Welding) is one of the industry's most widely used welding methods. SMAW welding requires preheating (preheating) to reduce residual stress, distortion, and cold cracking in the weld metal. Preheat also can affect the microstructure and hardness of the weld metal. This study aims to analyze variations preheating on SS400 and ST60 steel against micro tests by SMAW welding, namely electric arc welding with covered electrodes. Temperature variation preheating used in SS400 steel was 140°C, 170°C, 300°C and 400°C in ST 60 steel. The results showed that the higher the temperature preheat, the larger the grain size of the microstructure in the parent metal region, the heat-affected area, and the weld metal area. The higher temperature preheat also led to a decrease in violence in the three areas. ST60 steel has a larger microstructure grain size and lower hardness than SS400 steel at all temperature variations preheat.
