国内自行车行业的组合件焊接,多数沿用盐浴炉浸焊工艺,虽然该工艺本身有一定的长处,但它也存在着一些无法解决的问题。例如:泛盐、生锈、热变形大,用两次能源一电加热等。所以盐浴焊在国外如日本、美国、西德等国家自行车行业焊接中均已被淘汰,取而代之的是液化石油气或天然气多咀焊新工艺,国内有许多厂家已经做了实用型 The assembly of the domestic bicycle industry welding, the majority of salt bath furnace followed the dip welding process, although the process itself has some strengths, but it also has some unsolved problems. For example: pan salt, rust, heat distortion, with two energy such as electric heating. Therefore, salt bath welding in foreign countries such as Japan, the United States, West Germany and other countries have been eliminated in the welding of the bicycle industry, replaced by liquefied petroleum gas or natural gas multi-nozzle welding new technology, many domestic manufacturers have done practical
