Seam welding apparatus (50) with a bearing support arrangement for a transversely movable upper welding wheel (51).
A cargo container (100) is manufactured using mash seam welding or CO2 laser welding technology.
A fuel tank manufacturing method manufactures, by using a seam welding machine, a metal fuel tank having a projection/depression portion in the path of seam welding.
The invention relates to the roll seam welding of container frames wherein a first welding procedure is carried out using welding rolls (10, 11) and subsequently the welded frame is fed to a second welding procedure using welding rolls (20, 21).
The edges (4a, 4b) are continuously imaged by an edge shape monitor (11) immediately before seam welding.
universal electrode wheel head
Provided is a seam-welding roller unit (30) comprising a welding roller (32) to be used for a seam-weld, and a housing (36) for holding the welding roller (32) rotatably.
As a result, the replacement of the welding roller is facilitated to enhance the working efficiency of the seam-welding apparatus.
Further, after seam-welding, the distribution of oxides in the welded portion is continuously measured by means of an ultrasonic flaw detector (15).
Many models of devices for socket welding of pipes made of polypropylene are equipped with a temperature setting regulator.
