Welding industry as the "tailor", is an important process in industrial production, the welding quality has a very important effect on the quality of the products, so it is of great significance in automatic welding production:
1、改善工人的劳动条件,降低对工人操作技术的要求。自动焊接时工人只是用来装卸工件,远离了焊接弧光、烟雾和飞溅等,对于点焊来说工人不必再搬运笨重的手工焊钳,使工人从强大的体力劳动中解脱出来。
1, improve the working conditions of workers, workers to reduce the technical requirements of the operation. Automatic welding workers are only used for loading and unloading workpieces, away from the welding arc, spatter and smoke, it will not be for spot welding workers handling heavy manual welding, liberate workers from strong physical labor.

2、提高劳动生产率。自动焊接可实现24小时连续生产,另外随着高速高效焊接技术的应用,生产效率将进一步提高。

2, improve labor productivity. Automatic welding can achieve 24 hours of continuous production, with the application of high speed and high efficiency welding technology, production efficiency will be further improved.

3、可否缩短产品改型换代的周期,减小相应的设备投资。可以通过修改程序来适应不同工件的生产。
3, can shorten the cycle of product modification, reduce the corresponding equipment investment. Can be modified to adapt to different parts of the production process.
(1)稳定和提高焊接质量,保证其均一性。焊接参数如焊接电流、电压、焊接速度及焊接干伸长度等对焊接结果起决定作用。
(1) to stabilize and improve the quality of welding and ensure its uniformity. The welding parameters such as welding current, voltage, welding speed and the length of the welding stem play a decisive role in the welding results.
（2）采用自动焊接时对于每条焊缝的焊接参数都是恒定的,焊缝质量受人的因素影响较小,降低了对工人操作技术的要求,因此焊接质量是稳定的。
(2) the welding parameters are constant for each welding seam, and the welding quality is affected less by the human factors, so the quality of the welding is reduced.
（3）而人工焊接时,焊接速度、干伸长等都是变化的,因此很难做到质量的均一性。
(3) when welding, the welding speed, dry elongation and so on are all changed, so it is difficult to achieve the uniformity of quality.
