Description
Известные способы определени склонности материалов к трещинообразовани м при сварке обычно осуществл ютс путем сварки вручиую крестообразных образцов из пластин и последующего подсчета отнощени суммарной длины трещины к суммарной длине сварных швов.Known methods for determining the propensity of materials to crack formation during welding are usually carried out by welding hand-handed cross-shaped samples from plates and then counting the ratio of the total length of the crack to the total length of the welds.
Основными недостатками этих способов вл етс зависимость определени склонности трещинообразовани от квалификации сварщика, неодинаковые услови наложени сварных пшов, а также невозможность определени напр жени , при котором происходит разрущение материала .The main disadvantages of these methods are the dependence of the determination of cracking tendency on the qualification of the welder, the uneven conditions of the application of welded psf, as well as the impossibility of determining the stress at which the material is destroyed.
Предлагаемый способ устран ет эти недостатки.The proposed method eliminates these disadvantages.
Особенность его заключаетс в том, что закрепл емую одним концом пластину контролируемого материала нагружают сосредоточенной силой, которую контролируют динамометром и прикладывают к другому концу пластины под углом 45° к ее поперечному сечению. Это обеспечивает возможность получени максимальных раст гивающих напр жений на краю пластины.Its peculiarity lies in the fact that the plate of the controlled material fixed by one end is loaded with a concentrated force that is controlled by a dynamometer and applied to the other end of the plate at an angle of 45 ° to its cross section. This provides the possibility of obtaining maximum tensile stresses at the edge of the plate.
На чертеже изображена схема, по сн юща осуществление предложенного способа.The drawing shows a diagram explaining the implementation of the proposed method.
Сущность этого способа заключаетс в следующем. Исследуемый образец, выполненный в виде пластины 1, закрепл етс на столе сварочного автомата двум болтами 2. Р дом с пластиной из технологических соображений располагаетс подкладка 3, предназначенна дл обеспечени стабильности процесса сварки при переходе на пластину /. Перед сваркой к пластине } прикладывают нагрузку под углом 45°. Нагрузку создают посредством троса 4, перекинутого через направл ющий ролик 5 и присоединенного к ст жной муфте 6. Определенную величину нагрузки, установленную перед сваркой, фиксируют посредством динамометра 7. Подобного рода приложение нагрузки под угломThe essence of this method is as follows. The test sample, made in the form of a plate 1, is fixed on the table of the welding machine by two bolts 2. Next to the plate for technological reasons, there is a lining 3 designed to ensure the stability of the welding process when switching to a plate. Before welding, a load is applied to the plate} at an angle of 45 °. The load is created by means of a cable 4, thrown over the guide roller 5 and connected to the coupling sleeve 6. A certain amount of load, set before welding, is fixed by means of a dynamometer 7. Such an application of the load at an angle

Welding is carried out in the direction of arrow a and is carried out on a machine with a non-consumable electrode with filing of filler wire in a protective argon atmosphere. For each material, a load is selected at which a crack appears in the welded joint. The resulting load is a characteristic of the tendency of the material to crack. The destructive load can be used to judge the stresses that occur in the metal during welding.
Предмет изобретени Subject invention
Способ определени склонности материалов к трещинообразованию при сварке, отличающийс тем, что, с целью обеспечени максимальных раст гивающих напр жений по краю пластины, ее закрепл ют одним концом и нагружают сосредоточенной силой, контролируемой динамометром и приложенной к другому концу пластины под углом 45° к поперечному ее сечению.The method of determining the propensity of materials to crack formation during welding, characterized in that, in order to ensure maximum tensile stresses along the edge of the plate, it is fixed at one end and loaded with a concentrated force controlled by a dynamometer and applied to the other end of the plate at an angle of 45 ° to the transverse its cross section.
