SHIELDING GAS ADVANTAGES

Some of the advantages of GMAW process as compared to other arc welding process are as follows:

• It is a continuous welding process and can be mechanised.
• Welding can be done in all positions.
• Higher welding speed.
• Deeper penetration is possible, which permits the use of smaller size fillet welds for the equivalent strength.
• Open arc nature of the process aids monitoring and control of the arc during welding.
• Higher metal deposition rate.
• Less distortion due to higher welding speed.
• Avoids the chore of cleaning a solidified slag from the surface of each weld pass.
