WELDING DEFECTS WITH DIAGRAM
Welding Defects (With Diagram) | Metallurgy
(2) Internal defects. 1. External Defects are irregular width of welding beads, deviation of the weld from the prescribed dimension, unfilled craters on the surface of welds, undercuts, slag on the surface of welds, porosity in the outer layer of a weld, visible cracks in and around the welds.
What is Welding Defects - Types, Causes and Remedies
What is Welding Defects? Welding Defects can be defined as the irregularities formed in the given weld metal due to wrong welding process or incorrect welding patterns, etc. The defect may differ from the desired weld bead shape, size, and intended quality. Welding
Welding defect - Wikipedia
OverviewMajor causesTypesA welding defect is any flaw that compromises the usefulness of a weldment. There is a great variety of welding defects. Welding imperfections are classified according to ISO 6520 while their acceptable limits are specified in ISO 5817 and ISO 10042.See more on enpedia · Text under CC-BY-SA license

Welding Defect - an overview | ScienceDirect Topics
M. Naeem, in Handbook of Laser Welding Technologies, 2013. 7.4.1 Weld defects. Welding defects such as porosity, lack of fusion, spatter, burn through, oxidation and different forms of cracking can occur during laser microwelding either due to material-related problems as outlined in Section 7.3.3 or during the welding process.
Defects in Welding Joints: Internal and External
Defects in welding joints can be classified into two types as internal and external. It includes Overlap, Undercut, Spatter, Crater, Excessive, convexity, Surface Porosity, Slag Inclusion, Surface Cracks, Lack of fusion, Necklace cracking and Incompletely filled groove.
Welding Symbols explained (with photos and video
Welding symbols are a set of information conveyed by the design department to the welding Engineer and the welding operator. It contains all the necessary information viz. welding position, dimensions and geometry of the weld, details of groove/fillet, welding process etc.
