Description
(54) СПОСОБ УСТРАНЕНИЯ ДЕФЕКТОВ СВАРНОГО ШВА ТИПА «КРАТЕР СВАРКОЙ ПЛАВЛЕНИЕМ(54) METHOD OF ELIMINATING DEFECTS OF WELDED SEAM TYPE "MELT WELDING
от пушки до поверхности свариваемых плит составл ло 80 мм.from the gun to the surface of the plates being welded was 80 mm.
Дл имитации по влеии дефектов типа кратер приводили перибдическое отключение источника питани . После разгерметизации камеры выполн ли отверстие на дефектном участке дл придани кратеру правильной конечной формы. Размеры конического отверсти не превышали ширины шва. Дл выполнени отверсти примен ли сверло 0 2 мм и коническую развертку. Затем в отверстие вставл ли вставку из сплава 1201 с размерами, соответствующими коническому отверстию, с небольшим выступающим участком над поверхностью плит величиной 3 мм. После получени вакуума проводили оплавление выступающего участка на режиме UycK 30 кв; JA ЮО; 60 ma неподвижным расфокусированным пучком с плавным увеличением тока луча до необходимой величины и последующим уменьшением до нул . Затем проводили повторный проход на режиме первого прохода . В зоне соединени поры и несплавл юи1 .ие отсутствовали.For imitation of leftover crater-like defects, the peribdical power supply was disconnected. After depressurizing the chamber, a hole was made in the defective area to give the crater a regular final shape. The dimensions of the tapered bore did not exceed the width of the seam. To perform the hole, a 0-2 mm drill bit and a conical reamer were used. Then, a 1201 alloy insert was inserted into the hole, with dimensions corresponding to a conical hole, with a small protruding portion above the surface of the plates of 3 mm. After the vacuum was obtained, the protruding section was melted in the 30kV UycK mode; JA SO; 60 ma with a fixed defocused beam with a gradual increase in the beam current to the required value and a subsequent decrease to zero. Then a second pass was performed in the first pass mode. In the zone of the joint, the pores and non-alloying were missing.
