As per the IS 800 : 2007 code, the gap between web plates and flange plates shall be kept to a minimum and for fillet welds, it shall NOT exceed ______ at any point before welding.
1 mm
IS 800:2007 Maximum Gap for Fillet Welds
When performing welding operations in steel structures, it is crucial to follow the guidelines provided by relevant standards like IS 800:2007, which is the Indian Standard for general construction in steel.
The question specifically asks about the permissible gap between components, such as web plates and flange plates, before they are joined together using fillet welds. Maintaining a minimum gap is important, but there is a maximum limit specified in the code to ensure the quality and strength of the weld.
According to Clause 10.5.2.2 of IS 800:2007, which deals with clearances and tolerances before welding:
- The gap between parts to be joined by fillet welds shall be kept to a minimum.
- For fillet welds, the gap shall not exceed 1 mm at any point before welding.
This limit is set to ensure that the fillet weld can properly fuse the two components together across the entire joint and achieve the required throat thickness and strength. A larger gap could lead to insufficient penetration or require excessive weld material, potentially compromising the structural integrity of the connection.
Therefore, as per IS 800:2007, the maximum permissible gap between web plates and flange plates for fillet welds before welding is 1 mm.
