Welding Services

We are leaders in the market for providing best range of Welding Automation

Welding Automation

with years of research and development we are now countrys no. One plasma welding manufacturer with vast experience in welding of stainless steels, inconel, titanium and other exotic metals.

applications and user industries

  • aerospace and space industries
  • cryogenics
  • foodstuff and chemical industries
  • machine and plant construction
  • automobile
  • railway
  • ship construction
  • tank equipment and pipeline construction etc.
  • plasma arc welding (paw)is an advanced version of the tungsten inert gas (tig) welding process.
  • the electric arc is formed between an electrode (which is always made of tungsten) and the work-piece.
  • the key difference from gtaw is that in paw by positioning the electrode within the body of the torch the plasma arc can be separated from the shielding gas envelope.
  • actually all welding arcs are (partially ionized) plasmas but, the one in plasma arc welding is constricted arc plasma.
  • the constriction increases the temperature of the arc and also gives it the shape of a fine beam.
  • this enables welding at high speed, greater penetration, narrow haz (heat affected zone) and minimum heat input to the job.
  • current and gas down slope- programmable current and gas down slope available for automatic closing of key hole during mechanized welding
  • igbt inverter based with analog/digital controls & integrated hf arcing systemthat tremendously increases its efficiency and switching characteristic
  • sensitivity- less sensitive to changes in arc length
  • increased consumable life- recessed electrode reduces the possibility of tungsten inclusions in the weld and can substantially increase the period between electrode dressings resulting in increased life
  • more productive- weld in a single pass up to 6 mm plates in square butt position and 10 mm plates in only two passes
  • low degree of deformation- keyhole mode of welding gives smaller heat affected zone resulting in reduced strength loss at the joint for heat treated metals, promotes less grain growth which gives better ductility
  • less embrittlement- reduced weld time results in less embrittlement by carbides and complex inter-metallic compounds for stainless steel and super alloys
  • less residual stress- equalization of distortion stresses results in less residual stress
  • reduced porosity- less filler metal required in keyhole mode significantly reduces porosity
  • customization of technical features possible
