 |
Minimal oxidation/contamination of the weld or base metal |
|
Reduces weld defects (oxide inclusions, porosity,
micro-cracking) |
|
Less distortion since high heat is not required to melt
through oxide inclusions |
|
Higher welding speeds can be utilized |
|
Automated equipment arc voltage controls are more stable |
|
Welding parameters can be standardized or optimized |
|
Less rework due to more even weld deposition |
|
Less post-weld machining or hand grinding |
|
Eliminates post-weld wire brushing or pickling to remove
oxidation in many cases |
|
Less material scrap |
|
Reduced inert gas consumption |
|
Longer electrode extensions are attainable |
|
Easy to install |
|
Built sturdy and reliably - will last for years
