1. Fundamental Working Principles<\/h1>\n<\/div>\n
\n

TIG Welding (Gas Tungsten Arc Welding, GTAW)<\/h3>\n<\/div>\n
\n
It generates high temperature through the electric arc formed between a tungsten electrode and the workpiece. Continuous argon gas shields the molten pool from air oxidation. It adopts surface heating<\/strong> with low energy density.<\/div>\n<\/div>\n
\n

Laser Welding<\/h3>\n<\/div>\n
\n
A high-energy laser beam is focused into a tiny spot to instantly melt or vaporize metals via keyhole penetration. It uses precision spot heating<\/strong>, with energy density hundreds of times higher than TIG welding.<\/div>\n<\/div>\n

3. Advantages & Disadvantages<\/h2>\n<\/div>\n
\n

TIG Welding<\/h3>\n<\/div>\n
\n

Ventajas<\/h4>\n<\/div>\n
\n
    \n
  1. Low-cost equipment, flexible startup, suitable for small-batch production, on-site maintenance and non-standard parts.<\/li>\n
  2. High assembly fault tolerance; workpieces with uneven gaps or dimensional errors can be welded.<\/li>\n
  3. Strong penetration for thick plates; welds feature high strength and toughness, ideal for load-bearing and pressure-resistant structures.<\/li>\n
  4. High versatility: welds nearly all metals including aluminum, magnesium, titanium, stainless steel and carbon steel.<\/li>\n<\/ol>\n<\/div>\n
    \n

    Disadvantages<\/h4>\n<\/div>\n
    \n
      \n
    1. Slow welding speed, high labor cost, inefficient for mass production.<\/li>\n
    2. Large heat input leads to severe deformation and oxidation discoloration on thin sheets, requiring extra polishing processes.<\/li>\n
    3. Highly dependent on skilled welders, who have high salary demands and are hard to recruit.<\/li>\n
    4. Generates strong ultraviolet rays and ozone, creating harsh working conditions.<\/li>\n<\/ol>\n<\/div>\n
      \n

      Laser Welding<\/h3>\n<\/div>\n
      \n

      Ventajas<\/h4>\n<\/div>\n
      \n
        \n
      1. Ultra-high efficiency and automation, widely used in sheet metal, kitchen hardware and new energy mass production lines.<\/li>\n
      2. Minimal heat input, barely no deformation on thin sheets; smooth weld surface drastically reduces grinding and polishing workload.<\/li>\n
      3. Non-contact welding with zero electrode wear; standardized parameters guarantee consistent weld quality across all products.<\/li>\n
      4. Capable of welding tiny precision components and dissimilar metals (copper-aluminum, steel-aluminum).<\/li>\n<\/ol>\n<\/div>\n
        \n

        Disadvantages<\/h4>\n<\/div>\n
        \n
          \n
        1. High costs for equipment purchase and maintenance; optical lenses require regular upkeep.<\/li>\n
        2. Strict precision standards for blanking and joint assembly; even minor gaps result in incomplete welding.<\/li>\n
        3. Difficult to weld highly reflective metals (pure copper, pure aluminum), requiring special customized laser machines.<\/li>\n
        4. Limited single-pass penetration for thick plates; multi-pass welding is less cost-effective than TIG welding.<\/li>\n<\/ol>\n<\/div>\n
