why employee need a career development? Maslow theory

Career for engineer why do companies offer career development to their employees? the position or job title for the engineer can be divided into several levels, for example, a junior engineer, engineer, lead engineer until senior engineer. There is even the uppermost position, which is called the Subject expert matter (SME) or Advisor and sometimes also called the Consultant. The lowest position, the junior engineer has the lightest task with the smallest salary. The more upward, the greater the task or authority. of course salary is also getting bigger. this career division for engineer positions is in line with Maslow’s psychological theory. Where everyone always wants to develop and has a desire for self-actualization. A Humanistic psychologist named Abraham Maslow developed a theory of personality that is able to influence many scientific fields. Maslow developed a theory that has a high degree of practicality so that it is easy to understand. This theory is also called Maslow’s theory. This theory describes reality. The contents of this theory can be easily understood because it contains features of human experience or behavior that have been experienced but never included in words. Maslow is a humanistic society where humanists do not believe that[…]

what is Heat Affected Zone – HAZ in welding?

Base metal vs HAZ Metals in welding results can be categorized into 3 parts, namely: base metal (initial workpiece), heat affected zone (heat affected area) and weld metal (weld metal). The base metal is a base metal part where heat and welding temperature do not cause changes in the structure or properties of the metal. The heat affected zone (HAZ) is a base metal that is adjacent to the weld metal which undergoes a thermal cycle of heating and cooling during the welding process so that this area is the most critical of the welded joint. Weld metal is a part of metal which at the time of welding melts and then freezes, the composition of the weld metal consists of the parent metal component and the added material from the electrode. The heat affected zone is formed during welding and includes the area of the material next to the weld, in which metallographic examinations can still detect structural changes through the welding process. These microstructural changes also change the properties of the material, so that the smallest possible HAZ is sought. This is achieved with low energy range, ie as concentrated as possible heat input at high welding speed,[…]

carbon equivalent formula and ce calculator

Why carbon content is important? The most widely used metal material in the industry is carbon steel and its alloys. Carbon steel is compounded based on carbon content and alloying elements. carbon content is one of the elements with the most influence on the nature or characteristics of a metal. The more carbon content, the metal becomes stronger and harder. however, hard material has brittle characteristics or is less resilient and increases the likelihood of cracking in the weld joint area. Explanations of the carbon equivalent One of the biggest problems in the welding technology of high-strength fine-grained steels is cold cracking. In general, the cold cracking tendency of micro-alloyed fine-grained steels is low. However, if higher carbon contents are present, there may be hydrogen-favored cold cracking in the heat affected zone. Since other alloying elements promote cold cracking in addition to carbon, carbon equivalents are often used to estimate crack sensitivity. There are numerous formulas for describing the carbon equivalent, in which the individual alloying elements are weighted differently. The carbon equivalent may thus generally be understood as a measure of the inclination of a cold cracking material depending on its chemical composition. It also serves as a basis[…]

weldability of steel

Weldability of steel and its carbon content

Which materials are weldable? Since the possibility of welding and welding safety can be strongly influenced by machines and aids, the consideration of the basic weldability of a substance is usually most important. It may happen that a substance that is not suitable for fusion welding, can be very well suited for a pressure welding. The weldability can therefore always be evaluated only in relation to a welding process . Weldability of components The weldability of components is decided on the basis of three criteria. Weldability is the ability of the fabric to be inseparably linked to the same or different fabric when using a welding technique. The possibility of welding refers to adequate equipment for carrying out the planned welding process, ie it is aimed at a suitable workplace. Welding reliability weighs the likelihood of deformation or other errors due to welding influences. Which properties should a weldable material have? “Weldability is available if, under consideration of qualitative and economic aspects, a spot welding meeting the requirements can be produced.” The most important ability of a substance is that it regains its strength after welding and after cooling. At the same time, however, high hot workability is beneficial for[…]
