Electrodes ok 46 certificate of conformity. Additional Specifications

Welding electrodes OK-46 are universal consumables for welding, as they are suitable for almost all spatial positions. In addition, they normally manifest themselves when working with direct and alternating current. The main target metals are carbon and structural, which covers a fairly large range of products. With their help, you can repair, as well as create metal structures and other engineering products. It should be noted that OK-46 electrodes ignite well, even if sparing welding modes with low currents are selected. This also applies to re-ignition when it is hampered by a molten end, or by a burnt coating.

Electrodes for welding OK -46 brand ESAB

Filler materials weld products with galvanized surfaces and other galvanized coatings without any problems. The electrodes are excellent for gap welding as they have a low level of heat input, which ensures a quality result even under these conditions. Increased manufacturability of the connection is achieved due to the extremely low sensitivity to contamination. Stable arcing and dense coating provides a sufficient level of protection against the influence of extraneous factors. You can meet this variety in any industry, as the qualities predispose to active use under any conditions, which is a definite advantage. During welding, a small percentage of metal spatter is observed, which is largely ensured by the ability to use low currents. A welding helmet and other accessories will help protect against spatter and bright arc light.

The properties are best manifested when working with seams, the root of which lies deep enough. It is not recommended to create long seams with such electrodes, as they are more designed to create short ones. Using this brand, you can get strong tacks that are created before the installation of metal structures. The electrodes are supplied in tight boxes that protect the material during transport. Items in the box are wrapped in airtight film to prevent moisture from accumulating in the coating when everything is in stock. This is a very common problem, so manufacturers have taken care of elementary security methods. Due to this, repeated transportation and long-term storage are allowed.

Specifications

When OK-46 electrodes are considered, the characteristic of their behavior is determined by the chemical composition. Indeed, here even a tenth of a percent of a substance can have a strong influence on the subsequent behavior during welding, as well as on the mechanical properties of an already finished seam.

Mechanical characteristics are not taken from the electrode itself, since the unmelted metal also has its own unique properties, and the weld in the already deposited state. This helps to understand whether this brand can be suitable for the operating conditions that the welded product will have to face. Thus, when choosing OK-46 electrodes, first of all, you need to study the technical characteristics. Here are some of the main ones:

Sizes and assortment

Hardfacing Features

Surfacing should be carried out in segments of relatively short length, even with a long weld length. To avoid problems during welding, it is necessary to strictly adhere to the available modes. For each value of the diameter of the rod, as well as for each position, there are values, the range of which will help to obtain a sufficiently high quality of the process.

Designation and interpretation

OK-46 electrodes for manual arc welding

Hello Dmitry! The connection of the flange with the pipe during the installation of the pipeline is one of the most important stages in its assembly. Therefore, the developers of welding electrodes pay so much attention to the technical requirements for the consumables used for this process. We do not recommend experimenting and arbitrarily choosing their type - you must be guided by the technological documentation. And in its absence - the recommendations of the developers. The thing is, everything matters.
- operating mode of the future pipeline (purpose, temperature, pressure, etc.);
- the material from which the parts to be joined are made;
- design of the welding electrode: material of the welding rod, its diameter and type of coating;
- welding current parameters (value, direct or reverse polarity, etc.), type of its source (transformer, rectifier or inverter), etc.
This is a whole science and it is impossible to cover everything in a short post. Briefly answering your question, let's consider both types of electrodes that interest you.
Welding electrodes of the "UONI" type (for example, "UONI 13 / 55R").
Note: hereinafter, in parentheses are the addresses of sites that describe in detail the consumables in question:
- areas of their application;
-characteristics of the weld;
-technological recommendations for use and a lot of other useful information.
Welding electrodes "UONI 13 / 55R", in the area we are considering, are used in welding root passes of pipes of strength class up to API 5LX70, filling passes API 5LX60 and in some other cases. But, they cannot be used when welding vertical downhill, as well as rotary and non-rotary joints of main pipelines.
Welding electrodes of the OK type (for example, OK 53.70 or OK 74.70) have a low hydrogen content and are used for one-sided welding of pipelines and general-purpose structures. When assembling pipelines:
- “OK 53.70” electrodes are recommended for welding filling and facing passes of pipe joints with strength class up to API 5LX56 and root passes with strength class up to API 5LX70;
-electrodes "OK 74.70" are mainly used for welding of facing and filling layers of fixed joints of pipelines. Including, in a vertical position for lifting strength class API 5L X60-X70 and other critical structures with a standard yield strength up to 500 MPa inclusive.
As can be seen from the description of the technical characteristics, electrodes of the "OK" type can be used for welding flanges. But, we strongly recommend that you follow the technological documentation for the assembled product or the recommendations that are available on the packaging of welding electrodes.
