Welding method with low cost, high strength in short period.
We can provide the low price but high strength method in the construction of steel frame in short period. It is applied in the field of house, office building, factory, commercial building, hospital, pool, parking building and etc. You can have a clear view of space. We do not use the welding backing strips nor the end tab which is normally using in traditional method, but we increase the thickness of plate, to make sure the thickness of throat can be obtained as the weld amount can be reduced. (reduce for 30～50％)
All of the welding process take place in downward direction, reduce the step, reduce the cost, but we can expect the strength of earthquake resistance to be increased as 2.5 times.
