自行车车架的中接头部位焊接,我厂采用的是盐浴焊接法,工业食盐(NaCl)作为加热介质,其焊接工艺流程如下:上工件→浸钎剂→烘干→盐浴焊(属钎焊)→下工件去盐。盐浴焊接法生产效率高、成本低,但存在着熔盐不易去尽及工作环境恶劣等缺点。这里影响工作环境的主要因素之一是盐浴焊接中产生的废气、盐雾弥漫于整个工作空间,长期以来得不到有效的解决,影响了操 Bicycle frame welded joints, I plant is salt bath welding, industrial salt (NaCl) as a heating medium, the welding process is as follows: the workpiece → leaching agent → drying → salt bath welding (solder Welding) → the workpiece to the salt. Salt bath welding production efficiency, low cost, but there is not easy to melt molten salt and poor working conditions and other shortcomings. One of the main factors affecting the working environment here is the waste gas generated in the salt bath welding. The salt spray diffuses throughout the work space and has not been effectively solved for a long time, thus affecting the operation
