寿县合兴浅谈钢结构安装焊接前的准备工作

发布时间:2015-10-20 9:26:33 浏览次数:560

这个项目的高层建筑在国内应用钢板太大及联合形式的代表相应的技术评价试验方法测试q345gjc焊接。钢- z15(墙画面),q345gjc - z15(4毫米壁),q345c(法兰厚度28 ),焊接位置打开水平位置及焊后包围。(桁梁凸缘焊接,焊接型有垂直位置,大小,沿着凹槽设计。这个物理实验焊接出现后,超声波检查。틈을抗拉强度强度标准值集合,共同180。该焊接材料及设备技术必须按照国家标准,性能良好。该装置清理熔渣焊条保温飞机,为什么一定要彻底,효과가。


电弧焊接工艺2气体焊接材料及设备


(1)的焊条应在高温干燥箱,电焊条,不超过两次。
(2)包装必须好,如果有。或。或弯或买线。
(三)排放权必须九十九点九%以上,纯度(体积比),水< 0 %(再)利用更高的压力,现在必须制止。

(四)焊工电压必须正常,公司推拿,确切的接触,电缆、电焊钳不均匀、机械浆,机构必须泄露或堵塞。



This project of high rise building in the domestic application of steel plate is too large and the joint form of the corresponding technical evaluation test method test q345gjc welding. Steel - z15 (wall painting), z15 - q345gjc (4 mm wall), Q345C (flange thickness 28), welding position to open the horizontal position and welding after welding. (girder flange welding, welding type has a vertical position, size, along the groove design. After this physical experiment was welded, ultrasonic examination. Tensile strength standard value set, 180. The welding material and equipment technology must be in accordance with the national standards, good performance. The device for cleaning slag electrode insulation aircraft, why must be thorough, not.
Welding process 2 gas welding material and equipment
(1) the welding rod should be in high temperature drying oven, electric welding, no more than two times.
(2) the packing must be good if there is. Or. Or bent or bought line.
(three) the discharge power must be above 99.9%, and the purity (volume ratio), the water < 0% (RE) to use higher pressure, and it is now necessary to stop.
(IV) welder voltage must be normal and massage. The exact contact, cable, non-uniform electric welding tongs, mechanical pulp, the agency must leak or blockage.
