1、常用施工工艺中英常用施工工艺中英中英文对照各种施工工艺大全1、 钢结构工程 Steel Project1.1 钢结构焊接 Welded Steel1.1.1 工艺流程 作业准备电弧焊接（平焊、立焊、横焊、仰焊）焊缝检查Process Ready to workArc Weld(Flat Welding、Stand Welding、Sidelong Welding 、Welding belief) Weld inspection1.1.2 钢结构电弧焊接:Arc Welding Steel:1.1.2.1 平焊:选择合适的焊接工艺,焊条直径,焊接电流,焊接速度,焊接电弧长度等,通过焊接工艺验证;
2、清理焊口:焊前检查坡口、组装间隙是否符合要求，定位焊是否牢固，焊缝周围不得有油污、锈物；烘焙焊条应符合规定温度与时间，从烘箱中取出的焊条，放在焊条保温桶内，随用随取；焊拉电源：根据焊件厚度、焊接层次、焊条型号、直径、焊工熟练程度等因素，选择适宜的焊接电流；引弧：角焊缝起落弧点应在焊缝端部，宜大于 10，不应随便打弧，打火引弧后应立即将焊条从焊缝区拉开，使焊条块结合与构件间保持24间隙产生电弧。对接焊缝及对接和角接组合焊缝，在焊缝两端设引弧板和引出板，必须在引弧板上引出后再焊到焊缝区，中途接头则应在焊缝接头前方 1520处打火引弧，将焊件预热后再将焊条退回到焊缝起始处，把熔池填满到要求的厚度后，
3、方可向前施焊；焊接速度：要求等速焊接，保证焊缝厚度、宽度均匀一致，从面罩内看熔池中铁水与熔渣保持等距离（23）为宜；焊接电弧长度：根据焊条型号不同而确定，一般要求电弧长度稳定不变，酸性焊条一般为 34，碱性焊条一般为 23为宜；焊接角度：根据两焊件的厚度确定，焊接角度有两个方面，一是焊条与焊接前进方向的夹角为 6075；二是焊条与焊接左右夹角有两种情况，当焊件厚度相等时，焊件与焊件夹角为 45；当焊件厚度不等时，焊条与较厚焊件一侧夹角应大于焊条与薄焊件一侧夹角；收弧：每条焊缝焊到末尾，应将弧坑填满后，往焊接方向相反的方向带弧，使弧坑甩在焊道貌岸然里边，以防弧坑咬肉。焊接完毕，应采用气割切除弧板
4、，并修磨平整，不许用锤击落；清渣：整条焊缝焊完后清除熔渣，经焊工自检（包括外观及焊缝尺寸等）确无问题后，方可转移地点继续焊接。Flat Welding : choice of welding technology, electrode diameter, welding current, welding speed, the length of arc welding, weld process verification; Welding : welding inspection clearance groove, assembly space whether it meets the req

13、弧长一般为 23;焊条角度根据焊件厚度确定.两焊件厚度相等,焊条与焊条左右方向夹角均为 45;两焊件厚度不等时,焊条厚度不等时,焊条与较厚焊件一侧的夹角应大于较薄一侧的夹角.焊条应与垂直面形成 6080角,使电弧略向上,吹向熔池中心;收弧:当焊到末尾,采用排弧法将弧坑填满,把电弧移至熔池中央停弧.严禁使弧坑甩在一边.为了防止咬肉,应压低电弧变换焊条角度,使焊条与焊件垂直或由弧稍向下吹.Welding process and the peace operation : basic welding, but they should pay attention to the following is
14、sues : under the same conditions, welding current and friction over the plate short-arc welding, arc length is generally 2-3 mm; According to determine perspective welding electrode thickness.
