焊条在使用过程中会产生焊接烟尘。1974年美国劳动卫生专业会议(ACGIH)提出各种焊条的焊接烟尘发生量为5毫克/米~3,目前世界各国对这个数值有采用的趋势。日本于1976年,在WES9004“焊接与切割环境管理”中,也把焊接烟尘量定为5毫克/米~3。为了控制焊接烟尘量,大都采用局部通风或整体通风的办法,但从根本上控制焊条使用中的发生源和发生量则是十分重要的。焊接时,焊条产生的烟尘总量与焊接方法、焊接材料和具体的焊接条件有关。但采用不同的发尘量测定方法也会产生不同的结果,所以
Welding rod in the use of welding fumes generated. In 1974 the American Conference of Labor Hygiene (ACGIH) proposed a variety of electrode welding soot amount of 5 mg / m ~ 3, the current world countries have adopted the trend of this value. Japan in 1976, WES9004 “welding and cutting environmental management”, also set the amount of welding soot 5 mg / m ~ 3. In order to control the amount of welding fumes, most of the local ventilation or overall ventilation approach, but fundamentally control the occurrence of the electrode in use and the amount is very important. Welding, the total amount of soot generated by the welding method, welding materials and specific welding conditions. However, the use of different methods of determination of dust will produce different results, so
