Description

ИзОбретение относитс  к области дуговой автоматической сварки и может быть использовано , налрИмер, При сварке швов электросварных труб конечной длины.The invention relates to the field of automatic arc welding and can be used, as an example, when welding seams of electric welded pipes of finite length.

Из1вестен способ заварки кратеров прИ дуговой свар.ке изделий конечной длины, по которому заварку кратера осуществл ют со скоростью , меньшей .первоначальной.From the well known method of welding craters for arc welding of products of a finite length, according to which the crater welding is performed at a speed lower than the initial one.

Предложенный способ позвол ет повысить качество сварных соединений за счет того, что на заключительном участ|ке стыка, равном 30-ilOO% длины сварочной ванны, в стык ввод т металлический порошок в количестве, достаточном дл  заполнени  кратерного углублени .The proposed method allows to improve the quality of welded joints due to the fact that at the final joint section equal to 30% ilOO% of the weld pool, sufficient metal powder is injected into the joint to fill the crater cavity.

Способ заключаетс  в следуюш,ем.The method is as follows.

На свариваемые кромки или в разделку заключительного участка свариваемого стыка , в месте предполагаемого кратера, нанос т равномерный слой металлического порошка , крьники и т. п. дл  увеличени  Объ2A uniform layer of metal powder, bricks, etc., are applied to the edges to be welded or to the groove of the final section of the weld joint, in the place of the intended crater, to increase the volume of the metal.

ема расплавленного металла в количестве, достаточном дл  заполнени  кратерного углублени . Величину участка свариваемого стыка, на который нанос т лорошок, Принимают примерно равной, но |не большей длины сварочной ванны (30-100% длины сварочной ванны). Заварку кратера ведут со скоростью 60-85% от начальной скорости.sufficient amount of molten metal to fill the crater cavity. The size of the area of the welded joint, on which loroshk is applied, is taken to be approximately equal, but not greater than the length of the weld pool (30-100% of the length of the weld pool). Crater welding is carried out at a speed of 60-85% of the initial velocity.
