Can I use butt welding to weld steel? What are you asking for? What specifications are you looking for?
Can be welded, butt welding quality level requirements are relatively high, should be welded through, according to I quality grade acceptance.
This is not a targeted specification, but there are welding specifications for ships, bridges, roof trusses, and load-bearing composite steel frames. You can compare it.If you can't find the standard, these things have a general specification. For example: welding personnel must have the corresponding operation license, if we find that the conditions of the people, will naturally find the specification; the other is not to say, what a groove, welding rod, argon arc welding backing drying overlay, interlayer grinding, the process of welders understand, do not know if you don't with the.
Certainly. The I-beam on the long span single beam crane is welded. Otherwise, more than 20 meters of I-beam in the carrier also has problems.The main requirements is docking two I-beam to try to level up, up and down all around and then find it, in order to avoid deformation.Norm I don't know.Crane manufacturer personnel.
Large span single girder crane on the I-beam are welding, the main requirements is docking two I-beam to try to level up, up and down all around and find it, in order to avoid deformation.Without special specifications, we can refer to the contents of the welds in the seventh chapter of the code for design of steel structures.
