American Metal Fab: Essential Welding Processes for Modern Fabrication

As discussed by Lincoln Tech in their article “Popular Types of Welding Processes Explained,” working with metal involves transforming some of the world’s strongest materials into desired shapes and products. This skill, while exciting and empowering, requires significant work, practice, and guidance from industry professionals.

Lincoln Tech emphasizes the importance of understanding the entire welding process from start to finish. Mastery of each level is essential for becoming a versatile and proficient welder. The institution provides comprehensive hands-on training, enabling students to learn under the guidance of experienced field instructors. This practical approach ensures that students can effectively master the four major types of welding procedures, which are critical for their future success in the welding industry.

The Four Major Types of Welding Procedures:

  1. MIG (Metal Inert Gas) Welding:
    • Process: Uses a continuous wire feed as an electrode and a shielding gas to protect the weld pool from contamination.
    • Applications: Commonly used in automotive repair, construction, and manufacturing due to its versatility and ease of use.
  2. TIG (Tungsten Inert Gas) Welding:
    • Process: Utilizes a non-consumable tungsten electrode to produce the weld, with a separate filler material if needed.
    • Applications: Ideal for welding thin materials and requires a high skill level, often used in aerospace and art industries.
  3. Stick Welding (Shielded Metal Arc Welding or SMAW):
    • Process: Involves using a consumable electrode coated in flux to lay the weld, which protects the weld area from oxidation.
    • Applications: Widely used in construction, maintenance, and repair due to its simplicity and effectiveness in outdoor conditions.
  4. Flux-Cored Arc Welding (FCAW):
    • Process: Similar to MIG welding but uses a special tubular wire filled with flux, which allows for welding without an external shielding gas.
    • Applications: Popular in construction and heavy equipment repair for its efficiency and ability to weld thick materials.
