Beschreibung
Zusammenfassung:	FIELD: corrosion protection of welded seams in erection and repair of pipe lines. SUBSTANCE: prior to welding the pipes, circular blanks made from deformable protector alloys are placed at preset distance from ends of pipes and are secured by means of magnetic-discharge welding. Eatable protectors may be multi-layer and single-layer in form; protectors are made from aluminium alloys of different degree of deformation. EFFECT: enhanced reliability. 3 cl, 5 dwgd
