Practice has proved that the deformation of steel structure, the manufacturing, installation and bearing capacity, and the use of a great impact on the use of safety, and therefore to prevent deformation is more important than the rectification. Prevention of deformation can be considered from two aspects of design and process.
Wear resistant ceramic pipe
(1) the reasonable choice of member section to improve component of anti deformation ability to design institutions to try to make stable component, cut face said, thin-walled box member board layout should be reasonable, especially at both ends of the inner diaphragm to try to end portion are arranged; member of the hanging out shoulds not be too long; component placed or lifting and supporting parts should have enough stiffness. More easily deformed and not easy to be corrected in the form of structure to avoid the use of. Can be used in all kinds of steel, steel parts, bending parts and stamping parts instead of welding structure and welding deformation of large structure as far as possible the use riveting and bolt connection.
(2) a reasonable choice of welding size and arrangement of the weld seam position size is too large will not only increase the workload of welding, welding heat input, but also increase the welding deformation. So, in order to meet the strength and process requirements of the premise, as far as possible to reduce the size of the weld length and the number of weld. To contact weld the workpiece # each traverse the premise can be used point solid welding; the sealing requirements of the weld, as far as possible using ^? Continued weld. To prevent the hardening of the steel from the weld, the hard tissue, etc.. I-beam section is symmetric, weld is symmetrical to the neutral axis of the I-beam section, welding as long as welding sequence of reasonable selection of welding deformation especially deflection can be effectively controlled.
(3) the reasonable choice of weld cross section and slope, form groove and groove of Ding and cruciform joints, when the intensity of the same, groove filling amount of metal, in the groove, which to reduce welding deformation is favorable. With the open groove instead of open angle weld groove, can save a lot of manpower and material resources. Open groove butt weld, the different forms of groove weld metal difference is large, select the filling groove weld metal, to reduce welding deformation. So, in order to ensure the bearing capacity of the premise. Wear resistant ceramic pipe welding should be based on the thickness of the plate, welding method, welding process, and reasonable choice of weld size.
