Livio Building Systems Interview Questions, Process, and Tips

Weld material deposit can be calculated by determining the volume of the weld bead and multiplying it by the density of the material.

• Calculate the volume of the weld bead by measuring the length, width, and height of the weld.

• Multiply the volume by the density of the material to get the weld material deposit.

• For example, if the weld bead has a volume of 10 cubic inches and the material density is 0.3 lb/in^3, the weld

ASTM codes commonly referred for raw materials include ASTM A36, ASTM A53, ASTM A106, etc.

• ASTM A36 is a standard specification for carbon structural steel

• ASTM A53 is a standard specification for pipe, steel, black and hot-dipped, zinc-coated, welded and seamless

• ASTM A106 is a standard specification for seamless carbon steel pipe for high-temperature service

The weight of materials can be calculated by multiplying the volume of the material by its density.

• Calculate the volume of the material (length x width x height)

• Determine the density of the material (usually in kg/m^3)

• Multiply the volume by the density to get the weight

• Example: Weight of a 1m x 1m x 1m block of concrete with density 2400 kg/m^3 = 1m^3 x 2400 kg/m^3 = 2400 kg

Types of drawing include architectural, structural, mechanical, electrical, and plumbing drawings.

• Architectural drawings show the layout and design of a building.

• Structural drawings detail the framework and support systems of a structure.

• Mechanical drawings depict machinery and equipment.

• Electrical drawings illustrate the electrical systems in a building.

• Plumbing drawings show the piping and plumbing fixtures in a buil
