1. Slag acts as a protective barrier, shielding the molten weld pool from atmospheric contamination such as oxygen and nitrogen, which can cause defects in the weld.
2. Slag helps to control the cooling rate of the weld, allowing it to solidify slowly and evenly, which can prevent cracking and improve the overall quality of the weld.
3. Slag can also act as a flux, helping to remove impurities and oxides from the weld metal, improving the strength and integrity of the weld.
4. Slag can provide additional support and stability to the weld bead, helping to prevent distortion and ensuring a smooth and uniform appearance.
5. Slag can also help to control the shape and size of the weld bead, allowing for better control over the welding process and ensuring a consistent and high-quality weld.

1. Protection of molten metal: Slag forms a protective layer over the molten metal, preventing it from being oxidized by the atmosphere. This protection is crucial for maintaining the weld's integrity and preventing porosity.
2. Removal of impurities: Slag acts as a flux, removing impurities from the molten metal. These impurities can weaken the weld and cause defects. By removing these impurities, slag helps to improve the weld's quality and strength.
3. Control of weld shape: Slag helps to control the shape of the weld bead. It can be used to create a smooth, even weld or to produce a specific weld profile. By controlling the slag's flow, welders can achieve the desired weld shape.
4. Cooling of weld metal: Slag helps to cool the molten metal after welding. This cooling helps to prevent the weld from becoming too brittle or cracking. The slag's insulating properties help to slow down the cooling process, allowing the weld to cool gradually and evenly.
5. Prevention of undercut: Slag can help to prevent undercut, which is a defect that occurs when the weld metal does not fully penetrate the base metal. By forming a protective layer over the molten metal, slag helps to prevent it from flowing away from the joint and causing undercut.
