JOINING OF STEEL STRUCTURES
The steel structures should be joined using welding techniques, with both spot and seam welding processes being used.Spot welding should be used for joining steel structures with a thickness of up to 5mm, while seam welding should be used for joining steel structures with a thickness of more than 5mm.
When welding, preheating is necessary to reduce the risk of potential deformation of the steel structures. The temperature should be monitored and adjusted to the required level in order to ensure that it is suitable for the welding process. In addition, a shielding gas should be used to prevent oxidation during the welding.
The quality of the weld should be carefully determined before, during and after the welding process. Any welding defects, such as undercut and excessive porosity, should be carefully inspected and removed. Nondestructive testing should be carried out in order to determine the quality of the weld.
When welding steel structures, it is important to adhere to the flux-cored arc welding procedure. This procedure should include both preheating and postheating of the steel structures in order to ensure the reliability of the weld.
In order to protect the steel structures from corrosion, galvanic protection should be used. This is especially important when welding steel structures that are to be exposed to the elements, such as those that are used for outdoor applications. Galvanic protection is accomplished by using zinc coatings, which protect the steel surface from being exposed to moisture and other corrosive substances.
Finally, it is important to ensure that the welding has been done correctly and that all safety precautions have been taken during the welding process. Appropriate personal protective equipment should be worn while welding and fire protection measures should be employed in order to ensure the safety of everyone involved.
In conclusion, welding is an efficient and reliable method of joining steel structures. It is important to ensure that the process is carried out correctly and that all safety precautions are followed. Preheating and postheating should be used to reduce the risk of potential deformation of the steel structures and galvanic protection should be applied in order to prevent corrosion. Non-destructive testing should also be carried out to ensure the quality of the weld. By following these steps, the steel structures can be effectively joined and the risk of potential failure reduced.
