High Durability Surfacement Painted Or Galvanized High Rise Steel Building Construction
Thanks to its wide range of benefits, steel is the preferred material for construction in the commercial sector. Along with this, steel-framed systems provide a high level of prefabrication. Thus they can be used for projects within the city, guaranteeing high speed of construction and minimum on-site storage of materials. Steel enables builders to offer high-quality, flexible, and energy-efficient buildings while ensuring high-speed construction. Therefore, steel commands over 70% market share worldwide.

3. Fillet weld leg size:
3.1. Definition of fillet weld leg size(K):
Length of catheti from maximum isosceles triangle that drawn from the section of fillet welding seam.
For the fillet weld leg size without groove, please see illustration 1;
For the fillet weld leg size with PJP or CJP groove, please see illustration 2(take CJP for example)
.2. Fillet weld leg size requirements:
3.2.1. All the fillet weld size should not be less than the drawing and design values.
3.2.2. Minimum fillet weld size K≥1.5×,
t——thickness of thicker welding member(We could adopt the thickness of the thinner welding members when it is welded by low-hydrogen alkaline electrode). The minimum fillet weld size could be reduced by 1mm when it is adopted by sub-merged arch welding;
The fillet weld size should be in increased by 1mm when it is applying to the single side fillet weld of T section.
When the thickness t≤4mm, the minimum fillet weld size should be same with the member thickness.
3.2.3. Maximum fillet weld size K≤1.2t
t——thickness of thinner welding members(except the steel tube structure)
3.2.4. When the fillet weld being on the edge of welding members(t), the fillet weld size cannot exceed the edge of the welding member and the maximum weld size is as followings:
1)when t≤6mm,K≤t;
2)when t>6mm,K≤t-(1~2)mm
3.2.5. For fillet weld size in circular holes or trench holes, K≤(1/3)d
d——diameter of circular hole or short diameter of trench hole
3.2.6. For the fillet weld size without groove, it should not be more than 17mm. If it has to be more than 17mm due to the load consideration, out of economical factor, it should be changed to CJP or PJP fillet welding.
3.2.7. For the fillet weld that requires CJP:K≥t/4, see photos of 3(a)(b)(c). For the fillet weld size between web plate and top flange plate from some important members(e.g.if there is fatigue design requirement), crane beam or similar members, it could be t/2 and cannot more than 10mm meanwhile.
