Gedee Group Interview Questions and Answers

Isometric drawing of piping shows 3D layout of pipes while GA diagram of vessel shows general arrangement of vessel components.

• Isometric drawing of piping provides a 3D representation of how pipes are laid out in a system

• GA diagram of vessel gives a general overview of the arrangement of components within the vessel

• Both drawings are essential for understanding the layout and design of the piping system and vessel

WPS essential variables are key parameters that must be monitored and controlled to ensure the quality and integrity of a welding procedure.

• Essential variables include parameters such as welding process, material type, thickness, joint design, and preheat temperature.

• Monitoring and controlling these variables is crucial to maintaining the desired weld quality and mechanical properties.

• Examples of essential variables in welding procedures include voltage, current, travel speed...read more

Preheating is required to ensure even cooking and proper texture of food.

• Preheating allows the oven to reach the desired temperature before placing the food inside

• Helps in even cooking by starting the cooking process immediately

• Ensures proper texture and browning of food items

Different types of welding processes include MIG, TIG, stick, and flux-cored welding.

• MIG (Metal Inert Gas) welding uses a wire electrode and shielding gas to join metal pieces together.

• TIG (Tungsten Inert Gas) welding uses a non-consumable tungsten electrode and inert gas to create a strong weld.

• Stick welding, also known as Shielded Metal Arc Welding (SMAW), uses a flux-coated electrode to create the weld.

• Flux-cored welding uses a tubular wire filled with flux to shield the w...read more
