What MUST be done after completing a weld with the SMAW process?

After completing a weld with the Shielded Metal Arc Welding (SMAW) process, it is essential to chip the slag. This step is crucial because slag, which is a byproduct that forms on the surface of the weld as it cools, can inhibit the strength and integrity of the weld if not removed. The presence of slag can lead to issues such as poor adhesion and weaken the overall joint.

Removing the slag also allows for better inspection of the weld for any defects or inconsistencies that may need to be addressed. Ensuring the weld surface is clean and free from impurities like slag is a critical part of the welding process, as it prepares the weld for further treatments, such as painting or other surface finishing, and contributes to the longevity and durability of the welded joint.
