1.1.2钢结构电弧焊接:

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;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2~4㎜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15~20㎜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,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(2~3㎜)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3~4㎜,碱性焊条一般为2~3㎜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60~75°;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,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。

1.1.2.2立焊:
基本操作工艺过程与平焊相同,但应注意下述问题:
在同等条件下,焊接电源比平焊电流小10%~15%;采用短弧焊接,弧长一般为2~3㎜;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60°~80°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.

1.1.2.3横焊:
基本与平焊相同,焊接电流比同条件平焊的电流小10%~15%,电弧长2~4㎜.焊条的角度,横焊时焊条应向下倾斜,其角度为70°~80°,防止铁水下坠.根据两焊件的厚度不同,可适当调整焊条角度,焊条与焊接前进方向为70°~90°.

1.1.2.3仰焊:
基本与立焊、横焊相同,其焊条与焊件的夹角和焊件厚度有关,焊条与焊接方向成70°~80°角,宜有小电流、短弧焊接。

1.1.3冬期低温焊接:
在环境温度低于0℃条件下进行电弧焊时,除遵守常温焊接的有关规定外,应调整焊接工艺参数,使焊缝和热影响区缓慢冷却.风力超过4级,应采取挡风措施;焊后未冷却的接头,应避免碰到冰雪;钢结构为防止焊接裂纹,应预热以控制层间温度.当工作地点温度在0℃以下时,应进行工艺试验,以确定适当的预热,后热温度.
