Did you fabricate Built Up Sections? If yes, please explain the requirement of Built Up sections over Rolled Sections? What are the common problems do you face while fabricating Built Up Sections?

Question

Accepted Answer

Yes, I have fabricated Built Up Sections. Built Up Sections are required when the load-bearing capacity of Rolled Sections is insufficient.

Built Up Sections are made by welding two or more Rolled Sections together to increase their load-bearing capacity.
They are commonly used in construction of bridges, high-rise buildings, and industrial structures.
Common problems faced while fabricating Built Up Sections include welding defects, distortion, and buckling.
Proper welding techniques and quality control measures are necessary to ensure the strength and durability of Built Up Sections.

large size and over wait

Accepted Answer

Larger size and load capacity  Built up sections  which are fabricated  by welding and bolting  together  multiple steel plates .can be designed to have larger cross  sections areas  and moment of intertia compared nyo standard  rolled steel sections . This allows  them to support  heavier loads and taller  building  more effectively . over all the design  flexibility . Improved  load barring capacity .and enhanced  durability  of built up sections  make then a preference  choice for industrial building  columns. Where are structural requirements and operational environment  may warrant these advantages .

Accepted Answer

Yes, I have fabricated Built Up Sections. Built Up Sections are used over Rolled Sections for custom shapes, larger sizes, and higher load capacities. Common problems include welding defects, misalignment, residual stresses, and distortions during fabrication, which require precise techniques and quality control to ensure structural integrity.

Customization: Built-up sections are often designed and fabricated to meet specific requirements that rolled sections cannot fulfill due to their standard shapes and sizes. This allows for custom cross-sections that can better handle unique loads or design constraints.Size and Load-Bearing Capacity: Built-up sections can be made larger and more robust than rolled sections by combining multiple plates or sections. This is particularly useful for very large structures or for applications where high load-bearing capacity is needed.Cost and Availability: In some cases, the required size or shape might not be available as a rolled section. Fabricating built-up sections can be a more economical solution than custom-ordering large or unconventional rolled sections.Flexibility in Design: Built-up sections allow for greater flexibility in structural design. They can be tailored to specific load conditions or geometric requirements, offering more design options.Rolled Sections:Standardization: Rolled sections come in standardized shapes and sizes (such as I-beams, channels, angles), which simplifies design and procurement. They are readily available and often used in common structural applications.Manufacturing Efficiency: The production of rolled sections is highly efficient, with processes optimized for mass production. This makes them less expensive per unit compared to custom-built sections.Strength and Efficiency: Rolled sections are designed to be strong and efficient in terms of material use. Their production methods ensure a high strength-to-weight ratio, which is beneficial for many standard structural applications.Ease of Use: Rolled sections are easier to handle, transport, and install due to their uniform shapes and sizes. They are well-suited for repetitive or standard construction tasks.In summary, built-up sections are often chosen for custom or non-standard applications where specific design requirements must be met, while rolled sections are preferred for their efficiency, cost-effectiveness, and availability in standard shapes and sizes.
