自动电弧焊接目前在我国已经推广使用,有不少工厂拥有大量自动焊和半自动焊设备,但是焊接效率一般还不够高,其中主要原因之一是对设备不熟练和对焊接规范掌握困难。焊接规范一般是从各种表格中查获的,这样就要求掌握大批参考资料。另一方面,焊接规范经过试用后尚需进行调整,因此必须有一次“预试”的选择。利用经验计算方法来确定焊接规范,就可以大大简化查对工作。自动焊接规范的经验计算法是根据巴顿提出的原则加以改进的。巴顿认为熔深和电流强度成正比,其比例
At present, automatic arc welding has been widely used in our country. Many factories have a large number of automatic welding and semi-automatic welding equipment, but the welding efficiency is generally not high enough. One of the main reasons is that they are not familiar with the equipment and have difficulty in welding the specifications. Welding specifications are generally seized from a variety of forms, thus requiring a large number of references. On the other hand, the welding specifications need to be adjusted after trial, so there must be a “pre-test” option. The use of empirical methods to determine the welding specifications, it can greatly simplify the check work. The rule of thumb for automatic welding is based on the principles put forward by Barton. Patton believes that the penetration and current intensity is proportional to the ratio
