Final answer:
Metallic inclusions in a weld can occur in welding processes that use flux, including Shielded Metal Arc Welding (SMAW), Flux-Cored Arc Welding (FCAW), and Submerged Arc Welding (SAW).
Step-by-step explanation:
The welding processes that can result in metallic inclusions in the weld are primarily those that involve the use of flux, which can become trapped in the molten metal as it solidifies. Specifically, these processes include:
- Shielded Metal Arc Welding (SMAW)
- Flux-Cored Arc Welding (FCAW)
- Submerged Arc Welding (SAW)
Processes like Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW) are less prone to metallic inclusions because they generally use a shielding gas instead of a flux and provide better control over the weld pool.
