Defense Industry Armored Vehicle Resources
Welding plays a critical role in the manufacture and maintenance of armored vehicles in the defense industry. It is used to join various metal components, provide structural integrity and increase the vehicle's resistance to impact and ballistic threats. An overview of the welding process involved in the production of armored vehicles:
  1. Welding Methods:
  • Shielded Metal Arc Welding (SMAW): Also known as "stick welding", SMAW involves using a flux-coated consumable electrode to create an arc between the electrode and the base metal. The heat generated melts the electrode, creating a weld pool that solidifies to form a strong joint.
  • Gas Metal Arc Welding (GMAW): Commonly known as "MIG welding", GMAW uses a continuously fed wire electrode and a shielding gas to protect the weld pool from atmospheric contamination. The wire electrode melts and combines with the base metal to form the weld.
  • Flux Cored Arc Welding (FCAW): FCAW uses a tubular wire electrode filled with flux flux. Flux provides shielding and may contain alloying elements for improved welding properties. FCAW can be performed with or without shielding gas, making it suitable for outdoor applications.
  • Gas Tungsten Arc Welding (GTAW): Also called "TIG welding", GTAW uses a non-consumable tungsten electrode and a shielding gas. The heat produced by the electric arc melts the base metal and a separate filler rod can be added to form the weld.
  1. Weld Joint Preparation: Before welding armored vehicle components, the joint surfaces must be prepared to ensure proper fusion and strength. This includes cleaning surfaces to remove contaminants such as dirt, oil and rust. The joint can be prepared by various methods such as chamfering, chamfering or gouging, depending on the specific welding requirements.
  2. Welding Equipment and Safety: Welding armored vehicles often requires specialized equipment that can handle thick sheets of metal and provide high welding currents. This includes heavy-duty welding machines, welding torches and related safety equipment such as welding helmets, gloves and protective gear. Additionally, welding in the defense industry depends on strict safety standards and regulations to protect the welder, surrounding personnel and the integrity of the vehicle.
  3. Quality Assurance: Welding quality is extremely important in the production of armored vehicles. Non-destructive testing methods such as visual inspection, ultrasonic inspection, radiographic inspection and magnetic particle inspection are commonly used to ensure the integrity of welds. These tests help identify any defects, discontinuities, or potential weaknesses in welds, allowing for timely repairs or adjustments.
It is worth noting that certain welding processes and techniques may vary depending on the design of the armored vehicle, the materials used (eg steel, aluminum, composite), and the welding standards and characteristics followed by the defense industry or the relevant military organization.
