Flux Cored Wire Material Gas Shielded Arc Welding Thick Steel Plate Welded Crack Analysis

Abstract:

The world shipbuilding industry since the beginning of the last century with flux cored wire material.Since the flux cored wire material use welding materials has developed into a more efficient submerged arc welding consumables and gas shielded welding welding consumables and can be more easily combined with automated welding and robot welding.So far, flux cored material applications favored. Gas shielded arc welding consumables mainly divided solid wire and flux cored wire, flux cored wire applications has increased year by year because of its practicality and efficiency.Flux cored wire as the main welding consumables trends, especially in the thick carbon steel plate welded favored. In order to understand the nature of the thick-walled components weld cracking and produces original Due on a thick-walled T-joints butt weld ultrasonic flaw found Two crack metallographic and SEM fracture analysis.
