Problems solved by technology

[0002] At present, during the processing and welding of large steel structures such as shipbuilding, steel structures, pressure vessels, and building bridges at home and abroad, the welding quality of materials and welding materials is difficult to identify and the operation is not standardized. It is impossible to monitor and manage in real time; and environmental factors, factory conditions and The quality cannot be monitored, supervised, guaranteed, and guaranteed due to the lack of manpower, the accuracy of materials and the waste of materials cannot be guaranteed, and the waste of human resources (wasting time caused by workers queuing and registering when receiving materials, and after receiving materials , Warehouse staff registration and archiving, retrieving files causes secondary waste of time) and many other disadvantages:

[0003] First: The storage conditions for welding materials in the warehouse are not perfect; due to the specific conditions of the site, the welding wire storage standards (weather, temperature, humidity) cannot be met

When the material is delivered, there are errors in filling in the paper documents when the materials are received, false information cannot be identified, and the manual upload to the computer has a high rate of misrecording. The paper documents are easily damaged and lost. Serious queuing phenomenon, waste of invalid man-hours, receiving materials inconsistent with welding requirements, etc.), frequent technical quality accidents such as wrong receiving and misuse

[0004] Second: The management during the welding process is not standardized; when using the welding machine, operate at will, and the voltage, current, wire output speed, gas flow, and pressure of the welding machine required during welding cannot be supervised

Welding personnel cannot be managed, such as whether the welder has an operation certificate when using the welding machine, whether there is a welder grade certificate, whether the welding level is up to standard, whether it is operated in accordance with the process, and other issues cannot be fully supervised, and serious quality risks caused by incorrect materials, Even unlicensed operation, operation by outsiders, uncontrollable quality problems

[0005] Third: The used welding consumables cannot be preserved; after the welding consumables are opened, the temperature, humidity and ventilation should be scientifically preserved in strict accordance with the requirements of the welding consumables. Improper storage will cause the welding consumables to be corroded, scrapped and wasted

For unused welding consumables, poor storage will cause quality problems of welding consumables, directly and seriously affect welding quality, and it is not easy to detect, resulting in flaws in project quality. Welding according to the regulations does not match its welding position

[0006] Fourth: The phenomenon of waste is serious; scrapped welding consumables can be seen on the site to be discarded at will, unused welding consumables are abandoned for use, and empty trays are not fully recycled.

[0007] Fifth: The whole process of welding cannot be monitored in real time; the control personnel cannot control the welding quality due to many locations (plane, three-dimensional, internal), and track important parameters during welding (voltage, current, gas outlet stability, wire usage)

In addition, daily reports and inspections are all filled in manually, and there may be information discrepancies, maliciously cutting corners on products, artificially modifying and reporting daily forms, and other irresponsible and serious violations of quality assurance.
