What specifications of steel bars can be welded or not? What are the general rules?
It is required in the specification that the minimum welding diameter of steel bars above grade II steel should be above 16, which means that steel bars above 18 can be welded, and steel bars below 16 cannot be welded. However, there is a problem. This refers to the requirements of lap welding. The construction process environment and welding conditions of electroslag pressure welding are different from those of lap welding. At present, there is no provision in the specification. It depends on local regulations. In Shenyang, specifications \x0d\ of 14 and 14 and above can be used, and the welding diameter of grade I steel is also specified, that is to say, steel bars of 10 and above can be welded, and only \x0d\ can be overlapped below. In addition, it is forbidden to weld cold-worked steel bars.
