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[…]

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[…]

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[…]

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[…]
