This article analyses cost estimations with different welding technologies using global and local methodologies. In structural optimisation these costs are the goal functions to be minimised. We consider the relationship between design and fabrication technology, as well as the economy, using optimisation. These three elements work together to assist us in determining the best option. Only those cost elements that are directly relevant to the structural dimensions are considered in the local approach. A real structure’s cost function may comprise material costs, assembly costs, and other fabrication costs, such as welding, surface preparation, painting, cutting, edge grinding, and creating geometry.
Welding is the most common industrial procedure for combining metals, but it is also a significant producer of harmful fumes and gases. Depending on the welding technology, the amount of CO2, CO, CH4, NOx, etc., can be different. The global approach considers environmental issues such as global warming, ozone depletion, acidification, eutrophication, photochemical ozone production, and abiotic depletion. LCA is an objective approach for analysing and implementing alternatives to enhance the environment, as well as assessing the environmental consequences of a product, process, or activity.
