Arcraft Plasma Equipments ( I ) Pvt Ltd

Dahisar, Mumbai, Maharashtra

We are offering plasma welding machine. advantages of plasma welding:1. Less sensitivity to changes in arc length. 2. Recessed electrode reduces the possibility of tungsten inclusions in the weld and can substantially increase the period between electrode dressings resulting in increased life. 3. Weld in a single pass up to 6 mm plates in square butt position and 10 mm plates in only two passes. 4. 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. 5. Reduced weld time results in less embrittlement by carbides and complex intermetallic compounds for stainless steel and super alloys. 6. Equalization of distortion stresses results in less residual stress. 7. Less filler metal required in keyhole mode significantly reduces porosity.

Argon is basically used for arc plasma supply, powder transport and molten material shielding. It produces a very high quality deposit offering optimal protection with minimal dilution or deformation of the base material.It is a process that deposits very precise coatings of perfectly controlled alloys on mechanical parts that are subject to intense wear; significantly extending their service life.PTA technology is particularly effective in protection against corrosion, thermal shock and abrasion.A wide range of overlay alloys is available for practically any part.Some alloys are very hard; others are softer with hard abrasion-resistant particles dispersed in a matrix. Certain alloys are made to rebuild a part of required dimension while others are designed to be a final overlay that protects the work surface.

Submerged arc welding (SAW) is a s e m i - a u t o m a t i c o r f u l l y a u t o m a t i c consumable electrode arc process in which the arc is protected by a granular, fusible flux which blankets the weld puddle and surrounds the base metal to protect it from the atmosphere.Powder alloys can be added with the flux to utilize the existing heat produced by SAW to melt powders and thereby increase deposition rates.The flux stabilizes the arc, provides slag coverage, and also controls the properties of the deposit.Consumables are in the form of wire or strips.High deposition rates using current up to 1800 Amps in DC mode allows, Deep penetration, Easy slag removalSmooth and excellent quality welds are common with this process.

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.

The SPM is designed according to the customer job requirement and budget . Design options are offered as per the customers budget. The system consists of a hydraulic cylinder and power pack or servo motor for torch motion , pneumatic cylinder or spring loaded clamps to hold the job with suitable holder , well designed clamp and chills as per job thickness all assembled in a suitable machined frame . The whole system is designed and manufactured to the closest possible tolerances considering the minimum job thickness of only 0.1mm sheet capacity. The welding SPM can be used to weld any cylindrical jobs, strips , sheets where a precise linear fusion weld is required. The system is interfaced with TIG Inverter Pulse Power Source manufactured by Arcraft Plasma Equipments (I) Pvt Ltd. A control console is provided for easy operation of the SPM .

For longer length the machine can be designed accordingly. This machine does the job which has been so far reserved for costlier micro tig and micro plasma systems. Since it is fully automated the results are repeatable for high quality and fast production.
