What can I do with welded I-beam and welded H?
From the point of view of welding, there is no difference is the same welding, but the work of sub steel and H steel use is different, I-beam generally do lateral endurance, H steel generally do vertical station column use.
First of all, from the shape of: I-beam, each model has only two kinds, an ordinary type, and one is light, but light, rarely used.Type H steel, one in three, wide flange, middle flange, narrow flange.Purpose: steel beams are generally used for beams.Type H steel is generally used for columns, especially wide flange shaped steel, with mid flange and narrow flange for beams.The performance of H steel is higher than that of I-beam, but it saves material.As the beam, if the requirements of large vertical bearing capacity, generally with the high section type I-beam, and large horizontal force to the stability of the plane, generally using H steel, but the personal experience, to take in the flange is generally enough.About welding: as for the welding problem mentioned by landlord, there is no problem, H steel also has fillet, and avoid fillet when welding.
I-beam is generally rolled, the so-called welding "I-beam" may be called incorrect. "Welded H" steel refers to the three plates welded into H shape, as load-bearing components
