For ensureing processing and fabricating quality, in whole making link, need the Quality Control Links carrying out following operation:
(1), setting-out: each work progress such as steel plate cutting is cut, each parts and assembling parts, and the pre-splicing assembling of component has all needed professional linesman to carry out accurate setting-out on machined surface He in frock.Must check through inspector after setting-out, to guarantee the accurate of physical dimension, form and position tolerance, angle, installation contact surface etc. that part, parts, component are processed.
(2), line and number material: to less, comparatively simple plate, tubing when without Numerical control cutting necessity, adopt manually line, number material.Line, number material personnel should accomplish skillfully to make model, sample bar, and be familiar with symbol that model, sample bar mark and word connotation, the number of getting clear expects quantity.
(3), blanking cutting is containing groove: comprise gas cutting, intersection cutting and groove.The capital equipment of blanking cutting has Yi Sa-Chinese cock plasma panel, flame multi-head numerical control cutting machine, cart type torch-cutting machine, numerical-control tube to pass through cutter, beveling machine, horizontal band sawing machine, plate shearing machine etc. mutually.The requirement of processing by company inner quality standard inspection cut surface, physical dimension, form tolerance, cut-out section, splash etc., should be carried out rational stacking, does qualified mark and dash number after the assay was approved.
(4), welding operation specifies: welder qualification copy must by qualification welder's welding, and send owner supervisor for core by the welder that this engineering is engaged in welding.Non-solder personnel must not welding.Welding personnel establishes electric welding engineer, the management of specially department's welding job.Before welding, welding bead end face and each 50mm in left and right must remove rust, grease and other foreign material.During multiple tracks welding, after welding completes, must welding slag be removed, and remove welding bead with steel brush, if desired can welding except unclean object space with grinding-wheel grinder.During two-sided docking welding, before the welding of the back side, welding slag and unclean thing must be removed with the instrument such as emery wheel, steel brush.Dry welding rod must be used during welding to guarantee quality.The inspection personnel of welding bead, with visual inspection, if there is any defect to revise immediately, has quality person again to check, until pass through.
(5), welding inspection: the contiguity degree of composition backing and raw steel plate and termination are received, run-on tab fixing; The angle of groove; The cleaning of solder side; Preheating, thickness of slab is greater than the Q345 steel plate tacking place flame preheat 100 ~ 150 DEG C of 30mm; The state of tack weld is to check crack, lack of penetration.Whether welding method, welding parameter, preheating, interlayer temperature and welding after heat etc. are carried out on request.
(6), correct: rectification work runs through the whole process of structure steel fabrication, all should correct to blanking cutting, assembling hand welding etc. from before blanking, guarantee that scantling, quality, shape meet code requirement.This depends on the accuracy of equipment and the operability of technique.
(7), component surface process: the part after processing, parts, component all should be carried out in accordance with regulations edge processing, and removal burr, welding slag, weldering are pressed splash, dirt etc., and carried out surface inspection.After removing surface, surface derusting process is carried out with ballasting rust remover until component finished product.Derusting grade should more than Sa2.5 level.
(8), check and accept: component finished product should carry out in factory by under the guidance of technology, quality engineer, to check total quality and the installation situation of component, guarantee that scene can be installed smoothly, by exclusive surveyor, the inspection of component, result of the test are checked simultaneously, on component, the quality certification is sticked, for packing and dispatching from the factory after above inspection is all qualified.
The tolerance that in the present invention, in preparation method, rational assemble method and assembling sequence can cause each parts machining or cumulative limit are repaired in time, thus ensure the total quality of structure, therefore, adopt which kind of assemble method and assembling sequence particularly important to the quality of engineering.Every link of quality control of the present invention, layer by layer control, improves the quality fineness degree of component containing groove, welding operation regulation, welding inspection, rectification, component surface process, examination from setting-out, line and number material, blanking cutting.
As mentioned above, although represented with reference to specific preferred embodiment and described the present invention, it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite not departing from claims definition, various change can be made in the form and details to it.
