1、Analysis and countermeasures of overproof of the edge deviation of welding line in circular seam welding of boiler drum
2、The fixing and sealing may choose among parallel - seam welding, braze welding, glass - melting - sealing and resin binding.
3、Fundamental study on hybrid laser beam and resistance seam welding (LB-RSW)
4、Size is expected to start from the calculation, cutting, straight seam welding, the whole round, press-fit, girth welding, leak detection, have a certain degree of technical difficulty.
5、The mechanism of ultrasonic seam welding of copper plates and tubes for collecting solar energy was investigated.
6、The circumferential welding and the straight seam welding at all position can be realizable by using welding crawl equipment for all position together with the flexible metal band track.
7、The structure of a kind of imported seam welding electric oven and its failure reasons were analyzed. A new improved design for this kind of electric oven was introduced.
