Detrimental Elements: Importance of Removing Detrimental Weld Filler Elements from the Weld Prior to Coating
Formation of the proper pretreatment conversion coating and adhesion of subsequent coatings to welds is influenced by the cleanliness of the weld area. The welding process can create various inorganic soils depending on the welding process utilized. These inorganic soils must be removed to ensure the success of the pretreatment conversion and subsequent coating operations. This article provides information on the weld filler elements found in the weld that are detrimental to coating adhesion and also presents the recommended method of removal for these soils.
