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
