Control system for reducing weld spatter during the welding process by using high-speed visual sensing

Visual Sensing Systems for Arc Welding Process

Visual sensing technology is widely used in welding practices because visual devices are decreasing in price, increasing in reliability and improving in image processing hardware and software. As the most studied welding sensor, CCD(Charge Coupled Device) is more suitable for quality control of welding process than other means of sensing devices because it can obtain both two dimensional and th...

Visual Torch Position Control Using Fuzzy-Servoing Controller for Arc Welding Process

In this paper, we propose a fuzzy-servoing controller method for automatic welding. The proposed method uses a vision based arc tracking to find the initial points of the weld seam and to track them without a prior knowledge. Due to a serious melt down in the weld pool during the welding process, the method requires to control the welding torch in two directions, up-down and left-right directio...

the choice of automatic welding process and technology by using weld-exp. software

during last ten years, change of consumption pattern, variety and modernity of consumers, variety of producers and competitors, changes and vacillation rates, cause developing and decreasing the amounts of produce expenses by using hardware and software progressing, which are so important. in this respect, one of the possible solutions to increase the quality and enjoy the use of software possi...

consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
