Normal dimension are stated on the drawing. We should consider Assembly clearances ,welding grooves and machining allowances and dimensions adjusted accordingly prior to cutting .grind away hardened zone from all section surfaces(that are not be welded) if cutting is performed using heal-applying methods(gas/plasma/etc).
No parts shall be let un-welded unless clearly tsated on the drawing ,For efiocient and easy access it is recommended that sharp edges (that are not to be welded)are rounded to minimum R2.5 before assembling parts.
To ensure sufficient adhession for surface treatment all sarp edges shall be rounded to minimum R2.5, welding spatter beadsd and slag shall be completely removed ,Damage in surfaces shall be filed and grinded flush, negative thickness measurements are prohibited
