The need for high-quality visual inspection and control of the welded joint is explained by the fact that, for the most part, any mechanisms and structures in which welding is used are designed to withstand heavy loads.

Welding machines are widely used in construction and in the manufacture of durable metal structures, so the slightest deviation from technical standards What happened during their creation may carry significant risks. If the welds fail to cope with the load and break, there will be not only inevitable financial losses, but also casualties both during the construction phase and when the structure is put into operation.

Often, welded joints are checked during the construction process. This need is due to the fact that the seams, depending on operating conditions, may be subject to corrosion and other adverse effects.

Timely inspections are especially required when old worn-out structures or structures are overlaid with layers. In this situation, each applied layer is inspected and checked, the thickness and length of the connecting seam are measured, and all data obtained is compared with the established standard for a given area, taking into account its load.

Regular and high-quality visual inspections help to detect seam damage in time, in as soon as possible eliminate defects, as well as understand the cause of destruction, and find ways to eliminate and further prevent damage.

By whom and how a visual inspection is carried out, and a report is drawn up

After the work is completed, the initial quality check of the seam is carried out by the person who made the connection. After the initial inspection, control is carried out by others technical specialists: for example, site foreman, engineer, etc.

It is very important that specialists carrying out necessary knowledge on the technique of visual inspection of welded joints. Employees must have at their disposal necessary tools and devices. In addition, they must know how to correctly draw up a visual inspection report of welded joints, and draw it up in accordance with the regulations.

Thus, visual inspection is carried out in accordance with the following algorithm:

1. Visual control . Preliminary check of the connection for corrosion and possible defects with simple measurements: width, thickness of the seam, etc.
2. Inspection of welded joints. Quality control is carried out in order to obtain accurate parameters of external defects (after the conclusion of the certificate of preliminary inspection), the percentage deviation from the acceptable standard measures the size of damage to welds.
3. Detailed (instrumental) examination of seams and recording of results. On at this stage check deep defects and apply ultrasonic testing welded joints.

Specialists who carry out visual inspection of welded joints use several types of devices and tools.

Necessary devices

To carry out monitoring under various operating conditions, the following instruments are required:

1. Workshop devices. Such instruments can operate at temperatures from +5 °C to +20 °C at normal atmospheric pressure and moderate humidity.
2. Field devices. Such devices can operate in a temperature range from -55 °C to +60 °C and can withstand moderate shaking and precipitation.

When carrying out measurement control, the following tools are used:

• measuring magnifiers;
• calibration squares;
• protractors;
• calipers and depth gauges;
• probes;
• pipe wall meters and thickness gauges;
• micrometers;
• calibers;
• tape measures, rulers;
• special templates etc.

How to correctly draw up a visual inspection report for welds

Currently, the visual inspection report is drawn up in any form. It is drawn up on the basis of a template that is developed and approved by the organization carrying out the work.

Registration procedure

The act can be drawn up by hand or printed on a printer; to draw up the act, you can use a form with company logo organization and its details, it is also possible to use a simple sheet of paper.

The act must be certified by the signatures of the responsible persons, and it is drawn up in only one original copy and receives a unique number.

All data about the act is registered and a special accounting journal is entered, in which a mark is placed on the document number and the date of its creation. The act must be stored in accordance with the regulations and rules of the organization; it is stored in a separate folder in the company archive.

Information that must be included in the act

Despite the fact that the law does not regulate the precise form of drawing up the act, there are some information that must be recorded in it without fail:

1. The name of the organization is written at the beginning of the document, date of creation of the act.
2. Positions and details of specialists are registered who inspected the welded joint.
3. The main part of the act contains information about the performer of the work.: specialist position, full name. Also, the main part of the document contains information about the surveyed welds: their numbers, brand, etc.
4. All instruments and devices used during inspection and control are included., all the methods used, the results of the inspection and the work performed are prescribed, and brief recommendations are given on the methods of monitoring and inspection.
5. The results of the inspection and control carried out are summed up, the signatures of the responsible parties are affixed.

Sample of the act

Control of welds is a necessary part of the approval of various structures before operation. The methods and results of verification actions are reflected in a special act.

How to check welds

In fact, a variety of methods can be used to examine welds, for example, ultrasonic, magnetic, chemical, capillary and other high-tech methods. However, the classic one, which is still relevant and in demand today, is a simple visual inspection. Its purpose: to make sure that the seam is of high quality, well welded, and has no undercuts, sagging, burns, excessive scaliness or other flaws. The advantages of this type of research are quite obvious: it does not require high costs, at the same time accessible and quite informative, but along with this there are also disadvantages: subjectivity of the examination, low reliability, the ability to examine only the visible part of the seam.

Visual inspection can be carried out both with the naked eye (usually, if we are talking about large, clearly visible seams), and with the help of various devices, such as lenses, microscopes, endoscopes, flaw detectors, etc.

They are used to identify the smallest hidden defects that are difficult to detect by simply examining the outside of the weld (for example, microscopic cracks, nicks, delamination, fractures, etc.). At the same time, there are devices that are intended only for use in laboratories and those that can be used “in the field.” The latter are able to withstand any temperature and weather conditions (including those that have increased coefficient radiation, chemical, bacteriological, etc. danger to humans).

Why is weld inspection necessary?

The purpose of such an in-depth examination is quite obvious: as a rule, any structures that use welding are designed to withstand a certain, fairly serious load (this is especially true for building structures). And any deviation from technical standards that occurs during their manufacture threatens that the structure will not withstand and will break, which in turn can lead not only to financial losses, but also to a threat to the life and health of people.

Often, welds are checked not only after the structure is manufactured, but also during its operation - this is due to the fact that they may be subject to corrosion and other adverse effects. Also, regular checks are necessary when surfacing several layers on a worn-out structure, while each completed layer is monitored, the length of the weld, the thickness of the base metal are measured, and these data are compared with the established standard for this area, taking into account its load.

The frequency of inspections is determined by legal norms, as well as internal regulations of the company.

Timely and high-quality visual inspections make it possible to detect seam failure as early as possible, as well as understand the causes and find a way to eliminate them.

Who carries out the inspection and draws up the report

The initial quality check of the weld is done by the welder who performed it. Further control is carried out by other employees: for example, the site manager, engineer, etc. It is important that these persons have the necessary knowledge on the technique of visual inspection of welds, and were also equipped with the necessary instruments and devices. They should also have an idea of ​​how to formulate a visual inspection report for welds.

Act format

Today there is no uniform standard for the act, which means that it can be done in any form. However, if the organization has its own document template, which is developed and approved by management, then this should be used. It is good if the format of the act is specified in the accounting policy of the enterprise.

Features of drawing up a visual inspection report for welds

There are also no requirements regarding the execution of the act, that is, it can be written by hand or typed on a computer; a form with a company logo and details and an ordinary piece of paper are suitable for it. The only thing: if an electronic form was made, then it should be printed so that the signatures of the responsible persons can be placed on it. The act is made in one original copy, which must be assigned a number.

Registration and storage of the act

Information about the act must be entered in a special accounting journal, in which it is enough to make a note about its number and date of creation. The storage period for the finished act is determined by the administration of the enterprise individually, based on the norms established by law, as well as the internal needs of the company.

The act must be stored in a separate folder or in structural unit, in which it was formed, or in the archive of the organization.

If you need to draw up a weld inspection report that you have never done before, use the sample below and read the comments to it - they will help you draw up the required document without errors and ambiguities.

1. First of all, enter the name of the enterprise into the act, then assign a number to the document, indicate the date and place of its creation.
2. Next, enter into the report the positions and full names of the workers who inspected the weld (if these are representatives of different enterprises, indicate the names of each of them).
3. After this, proceed to the main part: include information about the performer of the work: position, full name, then enter here data about the welds that were examined: their number, steel grade and other identification values.
4. Indicate the instruments and devices that were used during the inspection, all methods used, their results, and also give recommendations for additional ways examinations.
5. At the end, be sure to summarize the current control and sign.
