How Welding defects ....

Question

Accepted Answer

Welding defects can compromise the strength and integrity of welded joints.

Welding defects can occur due to various factors such as improper welding technique, inadequate preparation, or faulty equipment.
Common welding defects include porosity, lack of fusion, undercutting, and excessive spatter.
Porosity refers to the presence of small holes or voids in the weld metal, which can weaken the joint.
Lack of fusion occurs when the weld metal fails to fuse completely with the base metal, leading to a weak bond.
Undercutting is a groove-like depression along the weld toe, caused by excessive heat or incorrect welding angle.
Excessive spatter refers to the expulsion of molten metal during welding, which can result in a rough and uneven surface.
Welding defects can be detected through visual inspection, non-destructive testing methods like ultrasonic testing or radiography, and destructive testing like tensile testing.
Proper training, adherence to welding standards, and regular quality inspections are essential to minimize welding defects.
