Quality Standard & Control:
With near 20 year warranty in the steel building industry,our company has standard on the quality of steel building. We have acquired the ISO9001 and CE certificate. The followings are the related standard that we strictly follow whether for the design and fabrication of steel buildings:
GB/T1591-2008/2018
GB/T11263-2010
GB/T 2518-2008
GB/T12754-2006
GB/T 1228-2006
Here we take an example on the Process, fabrication and quality control standard on fillet weld size.
1. Purpose
To ensure the quality of fillet weld, meeting up the technical requirements of welded members and improve the standardization of our fabrication, we specially formulate this regulation.
2. Application scope
This manual is applying for the design, fabricate and inspection for the fillet weld size.
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)
3.2. 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.
