Zeco Aircon Assistant Manager Interview Questions and Answers

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 we...read more

Types of defects include design defects, manufacturing defects, and marketing defects.

• Design defects are flaws in the product's design that make it unsafe or unusable.

• Manufacturing defects occur during the production process and result in a faulty product.

• Marketing defects involve improper labeling, instructions, or warnings about the product.

• Examples: A car with a faulty airbag system (manufacturing defect), a medicat...read more
