Description

Control method of steel structure welding quality control system

Technical Field

The invention relates to a control method of a quality control system based on steel structure welding operation, and belongs to the technical field of quality control methods.

Background

At present, in the process of processing and welding large steel structures such as shipbuilding, steel structures, pressure vessels, building bridges and the like at home and abroad, the welding quality of welding materials of materials is difficult to identify, the operation is not standard, and real-time monitoring and management cannot be realized; environmental factors, quality that factory conditions and manpower can't reach the scheduling phenomenon and cause can't monitor, supervise, guarantee, can't ensure the exactness of material and the waste of material, manpower resources are extravagant (the workman queues up, registers the waste time that causes when getting the material, after getting the material, warehouse personnel register and file, calls up archives and causes the waste time of secondary) and so on a great deal of drawback:

firstly, the method comprises the following steps: the storage condition of the warehouse for the welding materials is imperfect; due to site-specific conditions, the storage standards (weather, temperature, humidity) of the welding wires cannot be met. When the materials are delivered, the materials are picked up and filled with the paper documents, the filled false information cannot be distinguished, the manual uploading to a computer is high in wrong recording rate, the paper documents are easy to damage and lose, the quality monitoring cannot be guaranteed, the picking is complicated (the place is far away from the warehouse, the queuing phenomenon is serious during picking, the invalid working hours are consumed, the materials picked up are not consistent with the welding requirement materials, and the like), and the technical quality accidents of wrong picking, wrong use and the like frequently occur.

Secondly, the method comprises the following steps: the management in the welding process is not standard; the welding machine is operated randomly when in use, and the voltage, the current, the wire outlet speed, the gas flow, the pressure and the like of the welding machine can not be monitored when in welding. The welder can not manage, if the welder has or not operation certificate when using the welder, has or not welder grade certificate, whether the welding level is up to standard, whether according to the serious hidden quality trouble that technology formal operation scheduling problem can't accomplish comprehensive supervision, the incorrect material that causes, even no evidence operation, the outer personnel operation of grade, uncontrollable quality problem.

Thirdly, the method comprises the following steps: the used welding material cannot be stored; the storage of welding material after opening needs to carry out temperature, humidity, air permeability according to welding material requirement strictly and carries out the scientific storage, and improper preservation just can cause welding material to corrode and scrap, waste. To the welding material that does not use up, keep badly to cause the welding material quality problem, directly seriously influence welding quality to be difficult to perceive, make engineering quality have the flaw, when continuing to use, the lazy, the greedy drawing of more unable assurance operating personnel is convenient, do not accord with rather than the welding position according to the regulation welding.

Fourthly: the waste phenomenon is serious; the phenomenon that the scrapped welding materials are discarded at will when the welding materials are not used up, the welding materials are abandoned, and the empty material tray is not recycled completely is seen in the field.

Fifth, the method comprises the following steps: the whole welding process cannot be monitored in real time; the control personnel can not control the welding quality in a plurality of places (plane, three-dimensional, internal) and the like and track important parameters (voltage, current, gas outlet stability and welding wire usage) during welding. Moreover, the daily report and the report check are artificially filled, so that the behaviors of seriously violating the quality assurance that the information is inconsistent, and the product is not responsible for material stealing and material reduction, the reported daily schedule is artificially modified and the like can be caused maliciously.

The above points are key control elements regarding the welding quality of the product, and therefore, it is urgently needed to develop a welding quality control system capable of realizing real-time transmission, real-time quality control, and comprehensively improving and guaranteeing the product quality and efficiency in combination with the above essential problems.
