Influence of tack welding, executed by manual argon welding, and aberrations of the electronic bundle at electron beam welding concerning the welded junction on quality of the direct weld of the shell of the carrier rocket
This article shows results of the spent researches in the field of the engineering industry, aimed at the effect of welds by argon-arc welding and beam bias on the quality of the welded seam on the sample of the rocket carrier shell. Because of the constrained conditions of a vacuum chamber fit-up, we made with tacks by manual argon welding from the external and internal parties of welded plates. To test it has been applied three aspects tacks. Displacement of a vertex of a pencil concerning a welded joint minimum on the second part of a seam, and sections 1, 2, 3, 4 are with displacement of the centre of a beam from the centre of a joint on ≈1 mm and 2 mm accordingly. The conducted researches with application Ultrasonic control and radio graphical control and for separate samples tests show what of the used methods rendered a greater influence on quality of a seam.
