                      鋼結構制作焊縫控制要點
                      1.前期準備
                      1. preparatory preparation
                      建設單位必須首先組織設計單位對圖紙進行會審交底;其次對施工單位的專項方案進行審批。認真貫徹執行專項工程書面交底;樣板驗收、隱蔽工程驗收;焊工應持證上崗,證件認可的范圍也是不可缺少的管理資料。
                      The construction unit must first organize the design unit to make joint examination and make a presentation, and then examine and approve the special plan of the construction unit. Conscientiously carry out the written foundation of special project; sample acceptance and concealment project acceptance; welder should be on duty, and the scope of certificate approval is also indispensable management information.

                      2.焊縫成型要求
                      2. weld forming requirements
                      焊縫應均勻、整齊、高低齊平且與母材圓滑過渡。焊縫寬度要求每道焊縫的深寬比是1∶1;焊縫高度一般是寬度的2倍;焊縫每邊覆蓋寬度為2~4mm。90°角焊接的焊縫應成45°。焊縫表面不得有裂紋、未焊滿、根部收縮、咬邊、接頭不良、表面氣孔、夾渣、焊瘤、弧坑、燒穿和電弧擦傷等對動載有影響的質量缺陷。
                      The weld should be uniform, neat, high and even, and smooth with the base metal. The width of weld is required for each weld, the ratio of depth to width is 1: 1, the weld height is 2 times the width, and the width of each side of the weld is 2~4mm. The weld of 90 degree angle welding should be 45 degrees. There shall be no defects on the weld surface, such as cracks, unfilled, root shrinkage, bite, joint bad, surface porosity, slag, welding, arc pit, burning and arc bruising.
                      3.焊條使用
                      3. welding rod use
                      對接焊縫空間尺寸在2.5mm以內,使用直徑3.2mm焊條;空間尺寸在3.0~4.0mm之間,使用直徑3.2~4.0mm的焊條;空間尺寸在4.0~5.0mm,使用直徑4.0~5.0mm的焊條。焊條不應有藥皮脫落,焊心生銹的情況。使用低氫焊條或堿性焊條時,應注意和原材料相匹配,焊件厚度與焊條直徑焊接電流相符。
                      The space size of the butt weld is within 2.5mm, the diameter of 3.2mm electrode is used; the space size is between 3.0~4.0mm and the welding rod with diameter 3.2~4.0mm; the space size is 4.0~5.0mm, and the welding rod with the diameter of 4.0~5.0mm is used. There is no need for the electrode to peel off and rust. When using low hydrogen electrode or alkaline electrode, we should pay attention to match with raw material. The thickness of the welding piece is consistent with the welding current of the electrode diameter.
                      4.焊縫焊腳尺寸允許偏差
                      4. weld bead size allowable deviation
                      未焊滿偏差深度不大于1mm以上的每10cm長度內不大于2.5cm,一般全焊透的角接與對接組合焊縫不大于10mm。
                      The length of each 10cm is not greater than 2.5cm when the depth of deviation is not greater than 1mm, and the welded joint between the corner joint and the butt joint is generally less than 10mm.
