Metal Buildings Specification

The metal buildings uses steel to form a load-bearing structure. Generally, beams, columns, trusses, and other components made of section steel and steel plates constitute a load-bearing structure, which together with roof, wall, and floor, form a building.

Compared with traditional concrete buildings, metal structure buildings use steel plates or section steel instead of reinforced concrete, higher strength, and better seismic resistance. And because the components can be manufactured in factories and installed on-site, the construction period is greatly reduced. Due to the reusability of steel, it can greatly reduce construction waste and become more environmentally friendly. Therefore, it is widely used in industrial buildings and civil buildings all over the world.

Advantage
1. Greatly save construction time. Construction is not affected by the season
2. Increase the use area of buildings, reduce construction waste and environmental pollution
3. Building materials can be reused, stimulating the development of other new building materials industries
4. Good seismic performance, easy to transform, flexible and convenient in use, bringing comfort and so on
5. High strength, lightweight, high safety and wealth of components, and lower building cost

Disadvantages:
1. Heat-resistant and non-fire-resistant, fire-resistant coatings are required
2. It is susceptible to corrosion, and the surface needs to be coated with anti-corrosion coatings to reduce or avoid corrosion and increase durability

Welding serves as the primary technique for joining steel components, playing a decisive role in determining both the structural integrity and aesthetic quality of steel constructions. By harnessing the intense heat produced by electric arcs, welding rods and steel surfaces are melted and fused, resulting in strong, cohesive joints upon cooling. The reliability and longevity of a steel structure are thus intimately tied to the quality of its welding processes.

What Is Steel Structure Welding?

Steel structure welding refers to the process of uniting two or more steel elements through the application of heat, pressure, or a combination thereof. The objective is to establish a continuous, durable bond capable of withstanding mechanical loads and environmental challenges. Compared to mechanical fastening, welding offers a more seamless, efficient, and robust connection, making it the preferred choice in structural applications.

Given the diversity of structural requirements and material specifications, multiple steel structure welding methods have been developed, each tailored to particular conditions. Selecting the most appropriate technique is critical to ensuring both the safety and performance of the completed structure.

Steel Structure Welding Methods

1. Shielded Arc Welding (SMAW)

Often referred to as “stick welding,” Shielded Metal Arc Welding (SMAW) is one of the most traditional and versatile welding methods. It establishes an electric arc between a flux-coated electrode and the base metal, with the flux generating a protective shield to prevent atmospheric contamination.

Advantages:

  • Highly portable, making it ideal for fieldwork and outdoor applications
  • Relatively low equipment costs

Challenges:

  • Demands skilled operators to achieve consistent weld quality
  • Slower deposition rates compared to more modern techniques

2. Gas shielded arc welding (GMAW)

Gas Metal Arc Welding (GMAW), commonly known as MIG welding, employs a continuous wire electrode alongside a shielding gas (typically argon, carbon dioxide, or a blend) to produce clean, efficient welds.

Advantages:

  • High deposition rates with minimal post-weld cleanup
  • Well-suited for indoor fabrication and thin to medium-thickness steel sections

Challenges:

Vulnerable to wind and atmospheric contaminants, limiting outdoor use

3. Flux-cored arc welding (FCAW)

Flux-Cored Arc Welding combines elements of both SMAW and GMAW, using a tubular wire filled with flux that enables self-shielded or gas-shielded operations.

Advantages:

  • Capable of high-speed welding, even under less-than-ideal weather conditions
  • Excellent penetration, particularly advantageous for heavy sections

Challenges:

Post-weld slag removal adds to processing time.

4. Gas Tungsten Arc Welding (GTAW/TIG)

Gas Tungsten Arc Welding (GTAW), or TIG welding, utilizes a non-consumable tungsten electrode alongside an inert gas shield to produce welds of exceptional quality and precision.

Advantages:

  • Delivers superior weld appearance and integrity
  • Ideal for thin materials and critical structural joints

Challenges:

Requires greater operator skill and slower than other methods.

5. Submerged Arc Welding (SAW)

Submerged Arc Welding (SAW) involves feeding a wire electrode beneath a layer of granular flux, creating an arc that remains hidden under the flux blanket.

Advantages:

  • Extremely high deposition rates
  • Consistent weld quality with minimal environmental emissions

Challenges:

Primarily restricted to flat or horizontal welding positions

Submerged Arc Welding

Real-World Application:
In the construction of the Millau Viaduct in France, Submerged Arc Welding (SAW) was extensively used to join large steel segments. Thanks to SAW’s high deposition rates and deep penetration capabilities, welders achieved superior structural integrity while maintaining efficient production timelines, demonstrating SAW’s effectiveness for massive infrastructure projects.

Steel Structure Welding Materials

The selection of appropriate consumables is fundamental to achieving optimal weld performance.

Primary Welding Materials Include:

  • Electrodes: Must align with the mechanical properties of the base metal
  • Filler Metals: Selected based on strength, ductility, and service conditions
  • Low-Hydrogen Electrodes: Employed to mitigate the risk of hydrogen-induced cracking

When welding high-strength, low-alloy (HSLA) or quenched and tempered steels, careful matching of tensile strength and fracture toughness is imperative to avoid premature failure.

Essential Tools for Welding Operations

Successful welding depends not only on technique but also on the appropriate use of specialized equipment, including:

  • Welding machines (transformers, rectifiers, inverters)
  • Electrode holders and wire feeding systems
  • Grinding and chipping tools for slag removal
  • Precision clamping systems and jigs
  • Advanced monitoring devices and robotic welding arms

Welding Conditions and Compliance Standards

High-quality welds demand meticulous control over operational conditions:

  • Preheating: Moderates cooling rates to prevent cracking
  • Shielding Gas Flow: Must be stable and properly regulated
  • Clean Joint Surfaces: Essential to avoid contamination and defects
  • Temperature Control: Interpass temperatures must be carefully managed

Strict adherence to recognized standards, such as AWS D1.1 (Structural Welding Code – Steel) and ISO 9606 (Qualification Testing of Welders), is essential to ensure both structural safety and regulatory compliance.
