The most common health risk from welding is occupational lung disease, including lung cancer, but there are also acute and chronic health risks associated with welding fume, including risks to the eyes, the skin, and asphyxiation when welding in confined spaces.
What are the 3 most common defects in welding?
The most frequent welding defects that have an impact on strength are incomplete penetration and fusion, porosity, and slag inclusions.
What are 5 welding defects?
Following are the types of welding defects:
- Blowholes and porosity.
- Undercut.
- Fix a crack.
- Insufficient fusion.
- Included in slurs.
- partial penetration
- Spatter.
- Distortion.
What are causes of welding defects?
Causes:
- excessive welding current.
- Weld speed is too quick.
- incorrect angle use, which will concentrate more heat on free edges.
- The electrode is excessively big.
- improper application of gas shielding.
- erroneous filler metal
- bad welding technique

What are the external welding defects?
Surface Cracks, Undercut, Porosity, Overlaps, Crater, Underfill, Spatters, Excessive penetration, Arc Strike, etc. are examples of external welding defects that are found on the surface itself and can occasionally be seen with the naked eye.
What are advantages and disadvantages of welding?
Welding has a number of benefits, including the ability to be performed anywhere and without the need for adequate clearance, the creation of smooth surfaces, and the simplicity of their designs.
What are disadvantages of arc welding?
Disadvantages
- Lower efficiency: Arc welding typically produces more waste than many other types, which can sometimes result in higher project costs.
- High skill level – Arc welding project operators require a high level of training and skill, and not all professionals possess this.
