合兴钢结构浅谈钢结构典形节点的焊接顺序和工艺参数

发布时间:2015-10-20 9:31:43 浏览次数:559
(1)在柱子下面。耳板侧by 1 / 3对称焊厚度两耳板焊接工,切断。
(2)和耳板侧by 1 / 3对称焊厚度两焊工。
(三)by焊工焊接家庭两邻边。
(四)每两层之间的焊接接头应相互错开,我也要一层一层夹杂着两焊工焊接接头的焊接过程中温度测量的注意。
(五)焊接工艺参数
气体保护焊接排放权:焊丝直径1.2mm,280~320 A电焊接速度为350~450毫米/分钟
绝缘导线长度约为25~20mm及气体流量的80L去min,
29 ~ 34V电压120~150
5.4.2柱,与梁王,梁王
(1)低翼缘焊接梁腹板梁翼缘一直相对焊接,焊接。(2)焊下翼缘的凸缘上下法兰上焊接。
(3)如果法兰厚度大于30mm应下法兰旋转焊接。
(四)焊接工艺参数
气体保护焊丝直径排放权1.2mm,280~360 A电流焊接速度300至500 mm / min
绝缘导线长度约20毫米,气体流量为20至80L mm。

38V电压30至120~150



(1) under the pillar. Ear plate side by 1 / 3 symmetrical welding thickness two ear plate welding workers, cut off.
(2) and the ear plate side by 1 / 3 thickness of two symmetrical welding welder.
(three) by welder family two adjacent edges.
(IV) between every two layers of welding joints should be staggered with each other, I also want to a layer of a layer of mixed with two welders welding joint welding temperature measurement.
(five) welding process parameters
Gas protection welding emissions: wire diameter 1.2mm, 280 ~ 320 A electric welding speed of 350 ~ 450 mm / min
The length of the insulated wire is about 25 ~ 80L and the gas flow rate of 20mm to min,
29 ~ 34V 150 ~ 120
The 5.4.2 column, and Liangwang, Liangwang
(1) low flange welded girder beam flange has been relatively welding, welding. (2) welding on the flange of the flange of the flange.
(3) if the flange thickness is greater than that of the 30mm.
(four) welding process parameters
Gas protection welding wire diameter 1.2mm, 280 ~ 360 A current welding speed of 300 to 500 mm / min
Insulated wire length of about 20 mm, gas flow rate of 20 to mm 80L.
38V voltage from 30 to 120 ~ 150
