Plasma Automatic welding

  • What is the working principle of automatic plasma welding technology ?
    Plasma arc welding is an arc welding technology where ionized gas is ionized to produce high-temperature ionized gas. This ionized gas passes through a small hole in the center of a water-cooled nozzle via a special compression structure of the welding torch, forming a stable plasma compression arc. This arc melts the workpiece to achieve a greater penetration depth. It is generally classified into three types: transferred arc, non-transferred arc, and hybrid arc. The transferred arc process is the most commonly used.
  • What is automated plasma welding technology ?
    Plasma welding is a welding method that uses a plasma arc as a heat source. It is an automated welding technology that offers significant improvements in performance compared to traditional TIG welding. The plasma gas is typically pure argon, which has good ionization capabilities and arc stability. The shielding gas can be selected based on the material being welded.
    Stainless steel welding uses 95-97% argon + 3-5% hydrogen; rare metals such as titanium and zirconium use high-purity argon; carbon steel uses pure argon or an argon-hydrogen mixture. The selection of the plasma process method is determined based on the user's welding specifications.

K-TIG Automatic welding

  • What is the principle of K-TIG automatic welding?
    K-TIG automatic welding achieves the effect of a plasma arc through efficient electromagnetic compression of the arc. During welding, the arc energy is concentrated, and the arc pressure balances with the surface tension of the molten metal in the weld pool, forming a stable keyhole effect. This results in superior penetration capability, allowing for one-time welding of carbon steel plates up to 10mm thick, stainless steel plates up to 12mm thick, and titanium alloy plates up to 14mm thick. It is a novel welding technology between traditional argon arc welding and plasma welding, possessing both the aesthetically pleasing capping effect of traditional argon arc welding and the excellent penetration power of plasma welding.

Gantry Side-Beam Automatic Welding Machine

  • If the customer mainly produces stainless steel containers and has high requirements for back-side protection and corrosion resistance of welds, which is better, MIG/MAG or plasma welding?
