7 Most Common Welding Defects, Causes and Remedies

    • Weld Crack. The most serious type of welding defect is a weld crack and its not accepted almost Porosity. Porosity occurs as a result of weld metal contamination. The trapped gases create a Undercut. This welding imperfection is the groove formation at the weld toe, reducing the cross Incomplete Fusion. This type of welding defect occurs when theres a lack of proper fusion between Incomplete Penetration. Incomplete penetration occurs when the groove of the metal is not filled Slag Inclusion. Slag inclusion is one of the welding defects that are usually easily visible in the weld. Spatter. Spatter occurs when small particles from the weld attach themselves to the surrounding Procedures for Repair Welding and Surfacing ::Total

              MIG Problems and Remedies - Welders, Welding Wire,

              Welding processes that generate a slag such as Shielded Metal Arc Welding (SMAW) or Flux-Cored Arc Welding (FCAW) tend to tolerate surface contaminates better than GMAW since components found within the slag help to clean the metals surface. In GMAW, the only contamination protection is provided by the elements which are alloyed into the wire.
