Abstract

Изобретение относитс к сварке, а точнее к сварке плавлением соединений с угловыми швами, и может быть использовано при автоматизированных и механизированных способах сварки плавлением без применени присадочного материала. Цель изобретени - расширение технологических возможностей сварки угловых швов путем минимального проплавлени одной из деталей, уменьшени деформаций этой детали и улучшение качества сварного шва. Кромки как минимум одной детали 1 выполн ют с образованием угла β между плоскост ми стыка. При этом 30°≤β*9890°.

The purpose of the invention is to expand the technological capabilities of the welding of fillet welds by minimally penetrating one of the parts, reducing the deformations of this part and improving the quality of the weld. The edges of at least one part 1 are formed to form an angle β between the planes of the joint. At the same time 30 ° ≤β * 9890 °.

Claims

Claim

A method of welding fillet welds of T-joints, lap welds / AND corner joints, in which the top of the penetration zone is located in the mating plane of the parts, characterized in that, in order to improve the quality of welded joints by increasing the penetration depth of the joint plane of the parts while ensuring minimal penetration of one of the joined parts , to reduce deformations and improve the formation of the seam, the edge of at least one part is performed with a bevel angle greater than or equal to 30 °, but less than 90 °, and I install the details relative to one another to form an obtuse angle, the apex facing opposite to the heat source, the heat source is directed perpendicular to the axis line, adjacent to the bevel angle and obtuse angle, offset from the top by an amount equal to half the width of the joint.
