MIL-STD-3040 Base Document:2016

Specifies requirements applicable to various arc welding processes for welding and repairing armor welds which are constructed from qualified armor grade steel (wrought and cast armor grade steel).

This standard contains the minimum requirements for qualification of welding procedures, qualification of personnel, testing, fabrication, inspection, and repair of armor and non-armor steel weldments. This standard is intended to be used to facilitate the fabrications of new weldments, repair of existing weldments, and govern the requirements associated with any weldment made in accordance with this document. The qualification tests required by this document are devised to demonstrate the adequacy of the welding procedures and to demonstrate the ability of welders or welding operators to produce sound welds. This standard should not be applied in the cases of: structural tubular T-Y-K- connections; pressure vessels, or media moving or process piping under high or low pressure.
