Joining the Pieces Together with Welder or Rivets
Joining the individual metal pieces together is a critical step in the steel fabrication process. Two common methods of joining used in steel fabrication are welding and the use of rivets.
Welding involves the fusion of the metal pieces together by heating and melting the joint area. This is achieved using various techniques, such as shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW/TIG), and gas metal arc welding (GMAW/MIG). SMAW involves the use of an electric current to create an arc between the metal electrode and the workpiece, forming a weld. GTAW/TIG utilizes a non-consumable tungsten electrode and a separate filler material, while GMAW/MIG uses a consumable wire electrode, shielding gas, and filler material.
During the welding process, welders carefully control the heat and melting of the metal joints. As the metal cools, a solid and strong joint is formed. Filler metal may also be added to reinforce the weld or to create a larger joint. This ensures the durability and stability of the fabricated steel structure.
Alternatively, riveting is another method of joining metal pieces together. Rivets are metal fasteners consisting of a cylindrical shaft and a head. They are inserted through holes in the metal pieces and then hammered or pressed into place. This creates a permanent and secure connection between the pieces.
Both welding and riveting play crucial roles in the steel fabrication process, providing strength and stability to the finished product. These methods, when carried out with precision and expertise, ensure the integrity and longevity of the steel structures being fabricated.
Finishing the Product
Finishing a fabricated steel product involves a series of processes aimed at enhancing its appearance and protecting it from wear and corrosion. One essential step is surface cleaning, where any dirt, grease, or contaminants are removed to ensure proper adhesion of subsequent coatings. This can be done through methods like sandblasting or chemical cleaning.
After surface cleaning, coating application is carried out to provide a protective barrier and improve the product’s aesthetic appeal. Common coating options include powder coating, painting, or galvanizing. Powder coating involves applying a dry powder and then curing it with heat, resulting in a durable finish with a wide variety of colors and textures. Painting can offer similar benefits with the added flexibility for custom designs. Galvanizing, on the other hand, involves coating the steel with a layer of zinc to provide excellent corrosion resistance.
Throughout the finishing process, rigorous quality checks are conducted to ensure the final product meets the required standards. These checks may include visual inspections, thickness measurements of coatings, and adhesion tests. If necessary, additional finishing processes like polishing or the application of specialized coatings for rust proofing or fireproofing can be employed.
By diligently following these finishing processes, fabricated steel products not only achieve a visually appealing finish but also gain enhanced protection against wear, corrosion, and other environmental factors.
