What is the weld cleaning requirement stated in D1.1?

The requirement stated in the D1.1 code emphasizes the necessity for proper cleaning of welds to ensure strong and effective bonding. Specifically, every weld must be chipped and brushed to remove any contaminants, debris, or oxides that could adversely affect the quality and integrity of the weld. This cleaning process plays a vital role in preparing the weld surface, promoting better fusion and adhesion between the base metal and the welding filler material.

Chipping and brushing help to eliminate impurities that can lead to defects, such as porosity or weak weld joints. This requirement is grounded in the fundamental principles of welding that prioritize the quality and durability of welded structures. By ensuring that welds are clean and free from foreign materials, the integrity and performance of the welded assembly are significantly enhanced, supporting safety and reliability in structural applications.
