CONCLUDING MATERIAL

Covers the requirements for the fabrication of weldments by metal-arc welding processes, which weldments are constructed of homogeneous rolled and cast armor and the steel attachments to this armor. This handbook is for guidance only and cannot be cited as a requirement. If it is, the contractor does not have to comply.
