For guaranteeing the processing and fabricating quality, in whole making link, need carry out the Quality Control Links of following operation:
(1), setting-out: each work progress such as steel plate cutting are cut, and each parts and assembling parts, member are pieced together assembling in advance all need have professional linesman to carry out accurate setting-out with frock on machined surface.Must check through the inspector accurate with the physical dimension of guaranteeing part, parts, member processing, form and position tolerance, angle, installation contact surface etc. after the setting-out.
(2), line and number material: less, comparatively simple plate, tubing in the situation that necessary without the numerical control cutting, are adopted manually line, number material.Line, number material personnel should accomplish skillfully to make model, sample bar, are familiar with the symbol and the literal connotation that mark on model, the sample bar, and quantity is expected in the number of getting clear.
(3), the blanking cutting contains 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 mutually cutter, beveling machine, horizontal band sawing machine, plate shearing machine etc.The requirement of processing should be carried out rational stacking after the assay was approved by company's inner quality standard check cut surface, physical dimension, form tolerance, cut-out section, splash etc., does qualified sign and dash number.
(4), welding operation regulation: the welder that this engineering is engaged in welding must be welded by the qualification welder, and send owner supervisor standby nuclear the welder qualification copy.Non-welding personnel must not weld.Welding personnel is established the electric welding engineer, specially takes charge of the management of welding job.Before the welding, the welding bead end face and about each 50mm must remove rust, grease and other foreign material.During the multiple tracks welding, after welding is finished, must remove welding slag, and remove welding bead with steel brush, can weld except unclean object space with grinding-wheel grinder in case of necessity.During two-sided docking welding, must remove welding slag and unclean thing with instruments such as emery wheel, steel brushes before the welding of the back side.Must use dry welding rod with ensure quality during welding.The inspection personnel of welding bead if there is any defective to revise immediately, has quality person again to check, until pass through with visual inspection.
(5), welding inspection: the degree of connecting airtight of composition backing and former 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 100~150 ℃ of the Q345 steel plate tacking place flame preheats of 30mm; The state of tack weld is to check crack, lack of penetration as main.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, from correcting to blanking cutting, assembling hand welding etc. before the blanking, guarantees that scantling, quality, shape satisfy code requirement.This mainly depends on the accuracy of equipment and the operability of technique.
(7), component surface is processed: the part after the processing, parts, member should all 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.Until the member finished product and after removing the surface, carry out surface derusting with ballasting rust remover and process.Derusting grade should be more than the Sa2.5 level.
(8), check and accept: the member finished product should be by carrying out in factory under technology, quality engineer's guidance, to check total quality and the installation situation of member, guarantee that the scene can install smoothly, by the exclusive surveyor check, the result of the test of member are checked simultaneously, after above check is all qualified, stick the quality certification at member, for packing and dispatching from the factory.
Reasonably assemble method and assembling sequence can in time be repaired tolerance or cumulative limit that each parts machining causes in the preparation method among the present invention, thereby guarantee 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 contains groove, welding operation regulation, welding inspection, rectification, component surface processing, checks and accepts layer by layer control from setting-out, line and number material, blanking cutting, has improved the quality fineness degree of member.
As mentioned above, although represented and explained the present invention with reference to specific preferred embodiment, it shall not be construed as the restriction to the present invention self.Under the spirit and scope of the present invention prerequisite that does not break away from the claims definition, can make in the form and details various variations to it.
