Project Poster | Finding a solution to the bubbles that are created during welding in Aluminum.

Aluminum is common material used in the welding industry due to its suitable properties, Although aluminum welding generally has disadvantages. One of these weaknesses is the formation of porosity, which will affect the welded joint's mechanical properties. porosity is formed due to two mechanisms, shrinkage porosity caused by shrinkage during the metal solidification process and gas porosity caused by air trapping and undissolved hydrogen. The welding process often produces gases such as hydrogen, carbon dioxide and steam. During welding, the metal goes into a liquid state and then cools at a rapid rate. because In a liquid there is a higher solubility of a gas than in a solid, This may trap gases inside the material and create bubbles when the welding takes place. n order to minimize the problems with the porosity of the material due to welding, it is necessary to control the speed of the process, thermal gradient, dynamics of melt pool flow and solidification. Therefore, in order to solve this problem, we use laser beam welding.

Project Poster | How to prevent engineers' turnover at the plant

To reduce high turnover at the plant the managers propose different ideas, but it does not help. All proposed solutions are good, but there are some of them that are blocking the effectiveness of the rest of the solutions. The purpose of the project is to analyze the proposed solutions (perceptions) and define the blocked. The solutions with high blocking rank should be completed first to ensure the effectiveness of the rest of the ideas. The Perception Mapping (PMap) creative thinking tool was used for the blockers definition.
