In the actual production and manufacturing process, Jiangsu steel structure should control the welding process to prevent the occurrence of welding cracks.

1. Positioning welding: positioning welding is the easiest part of thick plate structure. When the thick plate is welded in position, the temperature of the welding seam is rapidly cooled by the "cooling medium" around it, resulting in local excessive stress concentration, cracks and material damage. The solution of Jiangsu steel structure is to increase the preheating temperature, increase the length of the tack weld and the size of the weld leg in the positioning welding of the thick plate.

2. Multi layer and multi pass welding: in the process of thick plate welding, an important technical principle is to adhere to multi-layer and multi pass welding, and wide pass is strictly prohibited. This is because the groove of the thick plate weld is very large, and a single weld can not fill the groove in the cross section. The result of rotary welding is that the restraint stress of the base metal to the weld is large, and the weld strength is relatively weak, which is easy to cause weld cracking or delayed cracking. The advantage of multi-layer and multi pass welding is that the former is the "preheating" process of the latter, and the latter is equivalent to the "post heat treatment" process of the former, which can effectively improve the stress distribution in the welding process and ensure the welding quality.

3. Inspection during welding: it takes several hours or even dozens of hours for thick plate welding to complete a part. Therefore, it is very important to strengthen the intermediate inspection in the welding process so as to find the problems in time. Jiangsu steel structure intermediate inspection can not stop construction, but can be carried out during construction and inspection. For example, during slag cleaning, check carefully for cracks. Timely detection and timely treatment.

Steel structure is closely related to the renovation of historical buildings, which has irreplaceable advantages in this new field. From the perspective of building renovation, steel structure has the advantages of light weight, strong expression and strong adaptability. Therefore, it stands out among many renovation materials and means and becomes the most common and easily obtained material in the reuse of historical buildings. In short, Jiangsu steel structure can meet the general sense of excellent building three standards: applicability, robustness and aesthetics.

Architecture in the 21st century is the structure of architecture. Architecture is no longer just for simple space or skin, but through the logic of architecture, the architectural structure, spatial structure and other parts are organically combined. Similarly, in the process of reconstruction and expansion of historical buildings, Jiangsu steel structure http://lasfinanzascambian.com/ The appropriate structural scheme can make the old and new buildings communicate and communicate at the architectural level twenty-one The architecture of the century is also of great significance.

It goes back to seventeen In the 20th century, steel structures were used to renovate, construct and transform historical buildings. from one thousand six hundred and sixty-seven Year to year one thousand six hundred and seventy Year, Carodi Perot The flat column roof of the Louvre was strengthened and repaired with forged iron members. Another architect Suffolo Cast iron components were used to strengthen the mountain flowers at the entrance to the pantheon in Paris.
