Adaptive control of full penetration gas tungsten arc welding
AbstructThis application paper addresses the control of a nonminimum-phase plant with variable large orders and delays. The process concerned is full penetration gas tungsten arc welding. Based on an analysis of accepted adaptive algorithms, the generalized predictive control algorithm presented by Clarke et al. is selected as the principal control strategy. An adaptive generalized predictive d...
متن کاملPenetration Testing: Alternative to Password Cracking
It is widely acknowledged that people, who are the weakest link in security, have a preference to use the same credentials on different computer systems, which forces us, the penetration testers, to evaluate this within our testing scenarios. Typical methods include brute-force password-guessing attacks (usually using common tools) or comparison of captured password hashes against published dat...

متن کاملClosed-loop power and focus control of laser welding for full-penetration monitoring.
We describe a closed-loop control system ensuring full penetration in welding by controlling the focus position and power of a 4-kW Nd:YAG laser. A focus position monitoring system was developed based on the chromatic aberration of the focusing optics. With the laser power control system we can determine the degree of penetration by analyzing the keyhole image intensity profile. We demonstrate ...
متن کاملEffect of welding parameters on penetration depth in FB-TIG welding of 5083 aluminum alloy
In the present study, effect of current, welding speed and preheat temperature during FB-TIG welding of AA5083 aluminum alloy was studied. Using the Taguchi method, 9 different tests were designed to investigate the effect of welding parameters on the penetration depth. Consistent with predictions, increasing the current and preheat temperature, and reducing the welding speed led to an increase...
