In recent years, there have been many steel structure workshops, and manufacturers also like to build with steel structures. What quality problems generally occur in steel structure workshops? Let’s take a look at them.

Complexity: The complexity of construction quality problems of steel structure workshops is mainly reflected in the many factors that cause quality problems, and the reasons for quality problems are also more complicated. Even if the quality problems are of the same nature, their causes are sometimes different, so the analysis, judgment and processing of quality problems also increase the complexity.

For example, weld cracks can appear not only in the weld metal, but also in the thermal influence of the base metal, either on the weld surface or inside the weld. The crack direction can be parallel or perpendicular to the weld, and the crack can be cold or hot. Improper selection of welding materials and preheating or overheating of welding also have some causes.

Severity: The severity of the construction quality problems of the steel structure workshop is as follows: affecting the smooth progress of the construction, causing delays in the construction period, increasing costs, seriously causing the collapse of the building, causing casualties, property losses and adverse social impacts.

Variability: The construction quality of the steel structure workshop will develop and change with the external changes and the extension of time, and the quality defects will gradually be reflected. For example, there are crack-free cracks in the weld due to changes in the welding stress of steel components: after welding, delayed cracking occurs due to hydrogen activity. If the member is overloaded for a long time, the lower arch should be bent and deformed, causing hidden dangers.

Frequent occurrence: Since modern buildings in my country are mainly concrete structures, managers and technicians engaged in building construction are not familiar with the manufacturing and construction technology of steel structures, and concrete construction workers are mainly migrant workers, lacking scientific construction methods for steel structures. It is understood that accidents occur frequently during the construction process.
