Welding machine grounding in the steel platform, may be bad contact, welders in the operation, why will the ground burned out of the cabinet in the electric control cabinet more
I was doing the construction, I encountered in the large steel structure plant, the bridge is generally walking along the crane beam, with the angle and the channel to do another bracket, no crane beams are generally along the pillars, so that the bridge Layout is better looking, but also facilitate the construction. Column of the bridge is also the use of angle and the like to do the bracket, this depends on the requirements of the bridge itself, as in the wall bridge, in fact, encountered a pillar but also turn, although it seems space utilization is big, but in fact To the construction of the inconvenience caused by a lot. Walking along the roof frame I have not encountered before. Can not give you any advice. I only from the construction point of view to consider this issue, not to mention design experience.
