Height,Website:http://www.lq-steel-structure.com, web and flange thickness, flange width according to customer requirements can choose steel welding adaptation. It can be used for variety of hot-rolled H-beam standard beyond.u  Select the steel variety. Hot-rolled H-shaped steel is mainly Q235B and Q345B, you need small quantities of special steel production plant impossible to produce. Steel can be welded can be selected according to need.u  High precision, good surface quality. Due to steel products of high precision, good surface quality, precision welding after so H is also high, surface quality stuff. Steel (for welding H-beam) has a thickness deviation is typically 0.0 millimeters to tenths of a millimeter, while the thickness of hot-rolled H-beam deviation is zero millimeters to 1 millimeter, a difference of nearly 10 times.u  Stable performance, good internal organization. Because from the smelting to casting to rolling, hot-rolled H-beam steel production than the technological requirements, equipment capacity, control level, high detection means, and therefore the internal organization of H-beam welding, chemical composition, various properties (mechanical properties, process performance, etc. ) indicators are reliable and stable.u  The presence of welding defects easily. Despite these many advantages, but due to welding forming, welding residual thermal stress exists in the welding area, different welding area organizations, the presence of tissue stress, easy to produce welding defects. With the welding and heat treatment level has improved continuously, gradually reduce these negative aspects, and now high-quality H-beam welding has been used in a variety of areas, including military, aerospace, including.
