Ground Combat Vehicle Welding Code - Steel

[introduction]

The military standard 'Welding Procedures for Structural Steel', Defense-015-0023 (Yeon), which was applied in our country, was created with reference to the US military standard MIL-STD-1261A (1968.9.30) and is a standard established in January 1975.
Some of these contents are from 1984.8.28.
It was abolished or as recently as 2003.7.28.
There were many cases where it was abolished.

TACOM(US
The Army Tank-Automotive and Armaments Command welding standard was compiled in April 2003 from the previously scattered MIL-STDs, and cross-references were changed to TACOM Drawing 12472301 Chapters 10, 9, and 8 for aluminum and TACOM Drawing 12479550, Ballistic welds, Critical welds, and Non-critical welds for steel.

Inspection methods include liquid penetrant testing (PT: Penetration Test), magnetic particle testing (MT: Magnetic Test), radiographic testing (RT: Radiographic Test), ultrasonic testing (UT: Ultrasonic Test), and visual testing (VT: Visual Test).
ASTM is adopted as the inspection procedure, and MIL-STD, MiL-HDBK, SAE-AMS, and AWS D1.1 CLAUSE 6 are adopted as the judgment criteria.

The relevant welding specifications can be downloaded from everyspec.com as TACOM12472301 for aluminum and TACOM12479550 for steel. Please refer to the original for any errors in the author's translation.
It is my hope that this translation will serve as a baseline for minimum communication in the welding of defense products.
