Defects of welded joints of the wire, causing breakages during drawing

Abstract

Based on the research experience of the wire raptures all weld defects are systematized. These stydies were done during the rough-the middle wire drawing and bronzing. The defects which most often occur breakages of wire were listed and requirements to the weld seam were established.
