电阻点焊虽然潜力诱人,但它易受焊机和零件许多可变因素的影响,使点焊质量不稳定。在焊接飞机发动机零件过程中,采用自动点焊质量保证系统,推动了三相点焊微处理机多因素闭环控制系统的最新发展。该控制器能保证每个焊点的质量,这就节省了对试样进行破坏性试验所花费的人力、物力。控制器能补偿的典型生产条件包括电极头磨损、零件装配不良以及氧化物、污垢形成的多变的零件表面状态。该系统另一优点是可以
Resistance spot welding, while potentially attractive, is susceptible to many variables of welders and parts, making the spot weld quality unstable. In the welding process of aircraft engine parts, the use of automatic spot welding quality assurance system to promote the three-phase spot welding microprocessor multi-factor closed-loop control system, the latest developments. The controller can guarantee the quality of each solder joint, which saves the destructive testing of the sample cost of human and material resources. Typical production conditions that the controller can compensate include tip wear, poor part assembly, and variable part surface condition caused by oxides and fouling. Another advantage of this system is that it is possible
