A 'weld symbol' is similar but different in that it is one specific symbol for one specific kind of weld. In my article on the different types of welds I showed you the 5 basic welds: fillet, groove, surfacing, plug, and slot. There is a specific weld symbol for each of these weld types, which is just one small part of the entire welding symbol.

Units. Torque has the dimension of force times distance, symbolically L 2 M T −2. Official SI literature suggests using the unit newton metre (N⋅m), or, joule per radian (J/rad). The unit newton metre is properly denoted N⋅m rather than m·N to avoid confusion with mN, millinewtons. The SI unit for energy or work is the joule.
