SAW Hardfacing (Submerged Arc Welding)
|
Descriptions:
- Submerged arc welding (SAW) is a s e m i - a u t o m a t i c o r f u l l y a u t o m a t i c consumable electrode arc process in which the arc is protected by a granular, fusible flux which blankets the weld puddle and surrounds the base metal to protect it from the atmosphere.
- Powder alloys can be added with the flux to utilize the existing heat produced by SAW to melt powders and thereby increase deposition rates.
- The flux stabilizes the arc, provides slag coverage, and also controls the properties of the deposit.
- Consumables are in the form of wire or strips.
- High deposition rates using current up to 1800 Amps in DC mode allows,
- Deep penetration,
- Easy slag removal
- Smooth and excellent quality welds are common with this process.
- SAW is a highly productive process for surfacing large areas.
- Fully automatic systems are used for heavy depositions in various areas such as
- Surfacing continuous casting rolls, Blast furnace bells,
- Forging die block, Inside of ball mill shell
- Welding of pressure / chemical vessels
- Arcraft has introduced very high quality of IGBT based inverter power sources suitable with advantages like
- Highly stable arc,
- Precision output control,
- Ease of operation,
- Thermal protection from overheating,
- Sturdy Tractor unit

Submerged arc welding is a semiautomatic or fully automatic consumable electrode arc process in which the arc is protected by a granular, fusible flux which blankets the weld puddle and SUTrounds the base metal to protect it from the atmosphere.
Powder alloys can be added with the flux. This utilises the existing beat produced by SAW to melt powders and thereby increase deposition rates .. The flux stabilises the arc, provides slag coverage, and also controls the properties of the deposit. Consumables are in the form of wire or strips. High deposition rates using current upto 2000 Amps in AC or DC mode, deep penetration, easy slag removal and smooth and excellent quality welds are common with this process. SAW is a highly productive process for surfacing large areas.
Fully auto mati c systems are used for heavy depositions in various areas such as surfacing continuous casting rolls, blast furnace bells, forging die block, inside of ball mill shell, etc.
