Polygamous steel project construction quality problems of complexity, mainly in the range of factors that lead to quality problems, the cause of quality problems are complex, even if the quality is of the same nature, and sometimes not the same reason, to analyze the quality of the determine and deal with increased complexity. Such as welding cracks, which can occur in the weld metal in the latest design of steel structures, may also occur in the heat affected parent material, either in the weld surface, but also within the weld; either parallel to the weld fracture strike Road, also perpendicular to the weld fracture can be either cold cracks, the cracks may be hot; also causes improper selection of welding materials and welding preheat or post-heat inappropriate points.
