This of course has steel beam manufacturers included.
After the customer confirms the final drawings, an order is signed and a 30% deposit is paid in advance. Our engineers refined the production drawings of the components within 10 days, as shown in the attached drawing model (the drawings are relatively large and will be sent separately).
The overall project involved manufacturing approximately 320.6 tons of goods within 2 months, which were shipped in 14 large containers. Please refer to the total parts list and tonnage statistics for details. Specifically, as follows:,
Material: Q345B.
Tonnage: 320.6 tons.
CFR ton price: 1409 USD/ton.
Quality requirements: Welding shall be carried out according to the customer's requirements and shall be inspected by a third-party international welding association. Magnetic particle testing shall be completely qualified.
Delivery time: 2 months.
Final payment: After the customer arranges for third-party testing to pass, they will pay 70% of the final payment before shipment.
(1)Reasonable optimization of welding process
The welding process for steel structural parts includes preheating, processing, and correction, and it is crucial to adopt the appropriate methods for each stage. Different methods of preheating, such as rigid fixing, pre-tension, and reverse deformation, should be used based on the characteristics of the steel structure. For example, the deformation of large steel structures during welding can significantly impact the overall product, and reverse deformation must be used during preheating to compensate for this. Additionally, controlling heat dissipation is vital to reduce the probability of weld deformation.
(2)Heat dissipation control during welding
Controlling heat dissipation during welding is essential to ensure even stress transmission and reduce the likelihood of weld deformation. Modern science and technology offer special means for heat dissipation during welding, which can greatly improve the quality of the welding process. While the operation process may be more complicated, the application effect is more evident.
Introduction to welding methods
Various welding methods are commonly used in the manufacturing of steel structures, each with its own principles and applications. Electrode arc welding, submerged arc welding, carbon dioxide gas shielded welding, MIG/MAG welding, and plasma arc welding are among the commonly used methods. These methods offer different approaches to achieve high-quality welds and are chosen based on the specific requirements of the steel structure.
Conclusion
In conclusion, the control method for steel structure processing and welding is crucial to achieve high-quality and durable steel structures. Factors such as the reasonable optimization of the welding process and heat dissipation control are key to ensuring the integrity of the final product. Additionally, understanding the principles and applications of different welding methods is essential to choose the most suitable approach for specific steel structures. At Jiahexin Steel Structure, we are committed to applying advanced welding techniques and ensuring the highest quality in the manufacturing of steel structures.
