电焊机的安全操作规程(三)
1、不进行焊接时(移动、修理、调整、工作间隙休息),应切断电源,以免发生事故。每月检查一次电焊机是否接地良好。
2、电焊机应放在通风、干燥处,放置平稳。检查焊接面罩应无漏光、破损。焊接人员和辅助人员均应穿戴好规定的劳保防护用品,并设置挡光屏隔离焊件发出的辐射热。
3、在载荷施焊中焊机温升不应超过A级60℃、B级80℃,否则应停机降温后,再进行焊接。电焊机工作场地应保持干燥、通风良好。移动电焊机时,应切断电源,不得用拖拉电缆的方法移动焊机,如焊接中突然停电,应切断电源。
4、电焊机、焊钳、电源线以及各接头部位要联结可靠,绝缘良好,不允许接线处发生过热现象,电源接线端头不得外露,应用绝缘布包扎好。电焊机与焊钳间导线长度不得超过30m,如特殊需要时,也不得超过50m长。导线有受潮、断股现象立即更换。
5、电焊线通过道路时,必须架高或穿入防护管内埋设在地下,如通过轨道时,必须从轨道下面穿过。应根据工件技术条件,选用合理的焊接工艺,不允许超负载使用,并应尽量采用无载停电装置。不准采用大电流施焊,不准用电焊机进行金属切割作业。
6、在焊接中,不准调节电流,必须在停焊时,使用手柄调节焊机电流,不得过快过猛,以避免损坏调节器。禁止在起重运行工件下面作焊接作业。
7、在有起重钢丝绳区域内施焊时,应注意不得使焊机地线误碰触到吊运的钢丝绳,以免发生火花导致事故。必须在潮湿处施焊时,焊工应站在绝缘木板上,不准用手触摸焊机导线,不准用臂夹持带电焊钳,以免触电。
8、完成焊接作业后,应立即切断电源,关闭焊机开关,分别清理归整好焊钳电源和地线,以免合闸时造成短路。施焊中,如发现自动停电装置失效时,应及时停机断电后检修处理。
9、清除焊缝渣时,要戴上眼镜,注意头部应避开敲击焊渣飞溅方向,以免刺伤眼睛,不能对着在场人员敲打焊渣。露天作业完后,应将焊机遮盖好,以免雨淋。

Measures for the routine management of moral education in Middle SchoolsMethod of conventional management of moral education in middle schoolFirst, the guiding ideology:School moral education is an organic whole of the whole education work, always adhere to the school adhere to the moral education, education for this product, and actively promote the quality education, the school building efficient curriculum system of moral education, moral education, improve the sense of attraction and appeal, enhance the moral education work for through and timeliness. Teach everyone, service education and management education, and school moral education work must be with family education and community education closely together, to form a concerted pattern, and strive to create a good atmosphere for education, and to promote the all-round development of students, to establish a scientific moral education full of vigor the For long-term mechanism.Two, the goal of moral education:To guide the students to form the correct world outlook, outlook on life, values, to
