In order to carry out a high-quality and complete assessment of the performance of various systems and structures on industrial enterprises control must be carried out welds, using several methods, e.g. All methods are divided according to the principle of influence on the object under study into two broad groups: non-destructive testing methods and destructive testing methods. The methods of the first group are preferable and more practical to use, but many of them are quite expensive and have their own characteristics. Therefore, it is more economical to start any weld inspection with the simplest method - visual quality control.

This control method is considered the most accessible and efficient and therefore is a mandatory preliminary examination method before carrying out any other method of testing the seam.

A simple optical method for confirming the quality of metal welding

Control of any welding joint begins to be carried out even when the weld is directly created. Visual control is part of the welder’s work, and he periodically conducts an external inspection (for lack of penetration, undercutting and leg fidelity) several times until the entire scope of work is completed. This is also the oldest method of monitoring the final work and its essence has not changed significantly, but the implementation method last years improved. Weld check

Theoretical definition and tools for implementation

Visual-measurement control (VIM) of welds is an external inspection of fairly large welded structures, both with the naked eye and with the help of various technical devices to identify smaller defects that are not amenable to initial visualization, as well as using converters of visual information into telemetric information. VIC refers to organoleptic (carried out by the senses) control methods and is carried out in the visible spectrum of radiation. A visual inspection in search of theoretical defects is carried out from the outside of the weld, where, if they are detected, minimal measurements can be taken using optical instruments and tools, and a visual inspection report can be concluded.

Inspectors use several types of tools when performing visual inspection of welded joints.

  • Survey, telescopic, floor magnifiers;
  • lenses;
  • microscopes;
  • endoscopes, etc.

To carry out monitoring under various operating conditions:

  1. Instruments for workshop purposes. Operating temperature range from +5 °C to +20 °C, conditions of complete rest, normal atmospheric pressure, moderate humidity.
  2. Field use devices. Operating temperature range from -55 °C to +60 °C, conditions of moderate shaking, vibration, precipitation.

The use of these devices allows for a more accurate search for defects and visual-optical quality control of welds on any objects.

Visual-optical control is the second stage of visual control with a wider, increased range of examination due to the use of optical instruments. Depending on the application, the method is intended for three main groups:

  • To search and analyze hidden objects. The following devices are used: endoscopes, borescopes, video systems, periscope flaw detectors.
  • To carry out inspection of objects remote from the flaw detector’s workplace. Range of application – a distance of no more than 250 mm from the controller’s eye. Equipment used: telescopic magnifying glasses, binoculars, spotting scopes.
  • For examining small nearby objects. The range of application from the specialist's eye is at a distance equal to or less than 250 mm. Equipment used: magnifying glasses, microscopes.

Visual inspection of welds is also required in conditions where the human senses are unsuitable for work. In areas such as: elevated temperatures, dangerous background radiation, external chemically active environment and others. And also in conditions where the configuration of the object under study and its design do not allow a full analysis of the quality and measurement of defects in welds (for example, due to the large height of the object or its underground location). Then, in addition to optical instruments, the following are used to search and analyze hidden objects:

Thus, visual information converters allow you to control welding seams baths of hot metal during the melting process.

Measurement control is an important component of VIC, which is carried out in accordance with strict control rules and regulatory documents governing quality. It consists of assigning a category or type to a defect according to one of the characteristics in the form of a specific physical quantity obtained through practical measurement. Measuring instruments and their metrological indicators are indicated in regulatory documents.
Measuring tool

During measurement control, the following tools are used, which may be included in the mandatory set of a technical supervision inspector or supplement it:

  • measuring magnifiers;
  • checking squares 90 0 pattern;
  • protractors with vernier;
  • calipers, calipers and calipers;
  • probes;
  • micrometers;
  • pipe wall meters and indicator thickness gauges;
  • micrometers;
  • calibers;
  • metal length meter (tape tapes, steel measuring rulers);
  • micrometric and indicator bore gauges;
  • templates: special, radius, threaded, etc.;
  • UShS-2, UShS-3 (templates for geometric parameters of seams);
  • surface plates;
  • a set of special accessories.

This control method, VIC, refers to methods that are feasible with a minimum set of tools. It consists of collecting information and is based on the qualifications of a specialist, the human factor, but allows you to draw up a visual inspection report of welds, which is considered an objective document.

The essence of external control

The quality of the formation of welds on the surface can be easily assessed during professional inspection. The characteristic of a “high-quality” or “poor-quality” seam is quite arbitrary, since this is a comparative value.

Quality control of welds and inspection of structures, pipelines, and buildings are carried out in three interrelated stages.

Step-by-step procedure for conducting the VIC

  1. Visual (measuring) control. Preliminary inspection of the seam for corrosion and possible defects with primitive measurements: width, thickness, leg.
  2. Quality control of welded joints. Quality control is carried out to clarify the parameters of visible defects (after concluding a preliminary inspection report), the size of defects and distortions of welds (percentage deviation from the permissible standard).
  3. Detailed (instrumental) research and recording of results. More precise methods are used:
  • eddy current method for determining the degree of weld wear and metal bending fatigue;
  • ultrasonic testing of welded joints to detect serious deep defects;
  • penetrant flaw detection for surface and through defects and so on.

Timely and high-quality inspections make it possible to identify the destruction of a seam or weldability defect in the early stages and then clarify the causes of the defect using any non-destructive flaw detection method.

Advantages and disadvantages of this technique

Advantages of the VIC method:

  1. A simple and accessible method.
  2. When collecting information about the quality of a design, it allows you to obtain up to 50% of the total volume.
  3. It is not labor-intensive and does not require expensive equipment.
  4. Easily tested and re-tested.

Disadvantages of VIC:

  1. The human factor, which influences 100% of the results.
  2. Low reliability of the results obtained, subjectivity.
  3. Used only to search for large defects (at least 0.1 - 0.2 mm) and suspected possible ones.
  4. Limitation of the study to only the visible part of the structure.
  5. The technical competence of employees is important; they must correctly select the measurement method, comparative template or standards and give an accurate assessment of the measurement results.

In terms of the method and quality of diagnosis, even imperfect visual inspection of seams is necessary method, both at the stage of complex diagnostics and throughout technological process.

Capabilities of the method for identifying defects

The following welds are subjected to visual inspection:

  1. when performing surfacing work at the “acceptance-handover” stage, a visual inspection certificate must be drawn up;
  2. when inspecting a multilayer welded joint (layer-by-layer inspection);
  3. during the final inspection of the places where the welding arc touches the surface of the base material.
  4. when assembling parts from assembly units under ;
  5. in the automatic production of welded parts and technical assessment quality of the material according to the technical process;
  6. upon expiration deadline operation of welds.

Visual inspection of welds requires mandatory measurement and exclusion of the following defects:

  • surface cracks;
  • visible gross defects;
  • poor quality of metal stripping in welding zones (especially technological fastenings),

as well as control and confirmation of availability:

  • branding (marking) of the seam and the accuracy of its production;
  • width and height of the seam, convexity and concavity of the seam;
  • correct sizes of fillet weld legs.

Defects that can be identified

When examining welds with the naked eye, you can assess:

  • uneven height and width of seams;
  • excessive scaliness;
  • influx;
  • undercuts;
  • excessive strengthening or weakening of seams;
  • unfilled craters;
  • burns;
  • parameters of fillet weld legs.

Magnifiers and microscopes allow you to detect: – a mandatory stage of working with metal.

Turning of metal sheets and parts is used using special equipment. Read more about this.

Areas of implementation of this technique

External inspection of the weld is carried out before the stripping, thermal or treatment procedure, as well as after its implementation.

When assessing the quality of a weld, VIC is used:

  1. As an informative method of describing the general external state.
  2. As a theoretical method for assessing the internal condition of a seam and as a reason for recommending a more accurate inspection.
  3. As an evaluation method of the operating conditions of a given seam, structure, system and the entire product.
  4. As a controlling method of detection gross violations technological process.
  5. As a method for preliminary conclusion during decommissioning or recording an emergency situation.
  6. As a predictive method of possible locations of structural failure for a specific set of visible defects found.
  7. As a final method for assessing and concluding on the correctness, safety and stability of the technological process of manufacturing or repairing a structure.

Visual and measuring control is very effective method checking and rechecking the quality of industrial materials and welded joints when performing construction work and upon receipt of the act of completion of construction, the act of commissioning, as well as various other technical acts.
