THE DESIGN OF SPLICES HAVE BEEN DONE BASED ON THE FOLLOWING CONSIDERATIONS. :-

1. THE MAIN MEMBER SHOULD BE BUTT WELDED BEFORE SPLICING.

2. ALL EDGES SHALL BE PREPARED BEFORE BUTT WELDING .

3. SPLICES SHALL NOT BE LOCATED AT THE POINT OF MAXIMUM BENDING MOMENT (i.e. AT MIDSPAN OF THE MEMBER ) AND / OR AT THE POINT OF MAXIMUM SHEAR FORCE (i.e. AT SUPPORT )

4. SPLICE PLATES ARE DESIGNED FOR 50 % OF FULL STRENGTH OF THE MEMBER. IT IS CONSIDERED THAT 50% OF THE TOTAL FORCE PASSES THROUGH THE BUTT WELD.

5. BUTT WELD SHALL BE SQUARE BUTT WELD FOR THICKNESSES UPTO 6 mm , SINGLE - V BUTT WELD FOR THICKNESSES UPTO 10 mm AND DOUBLE - V BUTT WELD FOR THICKNESSES GREATER THAN 10 mm.
