LEVEL OF EFFECT OF PREPARATION AND ASSEMBLY FOR WELDING ON QUALITY OF WELDED JOINTS FOR INDUSTRIAL PIPELINES

P.V. ZANKOVETS

Institute of Welding and Protective Coatings, NASB, Minsk, Belarus
 
 
Abstract
Investigations were carried out, and contribution of the effect of preparation and assembly for welding on the level of quality the welded joints in different dimension-type pipelines was estimated based on the experience of manufacture of welded industrial pipelines by using mathematical modelling and information technologies.
 
 
Keywords: manual arc welding, preparation and assembly for welding, industrial pipelines, welded joints, defectiveness, reasons of reject, dominant factors, quality level
