Advantages of PULSE MIG .
* less expensive per pound.
* permit lower feed rates. - reduced feed system wear.
* are easier to feed.(especially aluminum or other soft alloys)
PULSE MIG ADVANTAGES, Flexibility and Productivity.
- Nearly all metals can be welded in all positions.
- Range of weldable metal thickness is wide.
- Usually faster than SMAW,GTAW, and GMAW
- Short circuit transfer and spray.
- Distortion, dilution and HAZ. If less heat is entering the weld area, there will be a smaller heat affected zone, and less distortion. If penetration is minimized, reduced dilution rates are also yielded
- Typically adaptive to stick-out changes. Providing more consistent performance and penetration. Generally emits less metallic fumes than other GMAW processes.
Removes impurities from the weld puddle.Switching from peak to background current agitates the puddle causing impurities to float to the top of weld bead.
