13 Major and Most Easily Overlooked Problems in Steel Structure Welding
Steel structure is a construction structural form primarily composed of steel materials, assembled from components such as steel beams, steel columns, and steel trusses. These components are mainly made of section steel and steel plates, and are fixed to each other through welding, bolting, or riveting. Due to its advantages like light dead weight and convenient construction, it is widely utilized in fields such as large-scale industrial plants, stadiums, and super high-rise buildings. In the process of steel structure welding, there are numerous technical essentials that must be strictly controlled, as a slight oversight can lead to severe consequences. 1. Improper Selection of Welding Voltage Manifestation of the Problem: During welding operations, the same arc voltage is used regardless of whether it is backing welding, filler welding, or cosmetic welding, and without considering differences in groove dimensions. This practice makes it difficult to obtain the ideal penetration dep...
