•  According to the classification of slag properties, the LSAW can be divided into two categories: acid welded pipe rod and alkaline welded pipe. The electrode whose slag is mainly acid oxide is called acid electrode. The electrode whose slag is mainly alkaline oxide and calcium fluoride is called alkaline electrode.

• Acid electrode:

• 1. Not very sensitive to water and rust, baking at 100^150 for 1h before use

• 2. Stable arc, AC or DC welding can be used

• 3. Large welding current

• 4. Long arc operation possible

• 5. Poor transition effect of alloying elements

• 6. The penetration depth is shallow, the weld formation is better

• 7. The slag is glassy and it is easy to remove the slag

• 8. Normal and low temperature impact toughness of weld

• 9. The weld has poor crack resistance

• 1o. The high hydrogen content of welds affects plasticity

• 11. Less smoke and dust during welding
