Welding and Cutting Automation Equipment

SIECO has Fully Automated TIG and Plasma Welding with Cold and Hot wire process, High end Orbital Welding, Fully Automated Sub Arc Welding, Pulse MIG / MAG Automatic Welding in addition to the Manual / Automatic TIG Welding facility.

The automation of the process is done in both vertical and horizontal position. The low-profile bead shape reduces post-weld operations, producing weld beads that are flawless in appearance.

PPlasma welding is also well suited for the fabrication of spools of pipes upstream of the installation site. It allows subassemblies to be prepared and welded in the factory from Tubes, Elbows, Flanges and other parts, which are then fitted together.

OOrbital welding provides high precision welding in process pipe lines. It results in increased production and excellent quality with uniform deposit of weld metal to comply with International Standards and Customer Specification in particular for Pharmaceutical, Biotechnology, Food Processing and Chemical Industries.

  • Fully Automated TIG and Plasma Welding
    PI plasma 500

    The Plasma Welding Process is similar to Tig Welding Process. In Plasma Welding, the arc is sharply constricted by a cooled gas nozzle through which a flow of plasma gas is directed. The shielding gas flows through the outside gas nozzle, providing optimum gas-shielding to the weld-seam. The concentrated arc results in maximum energy focalization, leading to a deep-penetration effect in the work piece that can only be matched by a laser beam. The plasma arc is thereby an active part of the fusion process with an energy density that is up to ten times larger than the TIG arc. It forms a gas consisting of both positive charge carriers (ions) and negative ones (electrons). In order for plasma to form, very high temperatures of up to 25,000° C (45,000° F) are needed. Plasma welding is ideal process for applications where stringent quality demands are made of the weld-seam, for absolute freedom from porosity, perfect seam appearance and zero spatter.

    Hot Wire Process:

    The hot wire process in the quality of GTAW (TIG) or Plasma (PAW) produces a high quality weld at a high deposition rate. The system uses higher wire feed speeds and it is electrically preheated so that the wire enters the weld pool without undesirable chilling of the pool. Preheat is created by applying an AC current to the wire prior to its entering the weld pool. Current is applied as the wire passes through a contact tip in the hot wire torch. Because the wire is preheated, the hot wire torch provides gas coverage for the wire. This gas coverage is additional to the gas shielding of the welding arc.

    For optimum results, the wire is fed into the weld pool at a steep angle, approximately 50° to 60° from the horizontal and 0.15" to 0.2" (4 to 5 mm) behind the tungsten electrode. Wire stick out from the torch would normally be set at about ¾" to 1" (19 to 25 mm). This distance combines optimum heating of the wire and wire position control. Application: Fabrication of Pressure Vessels, thicker material, multi-pass welds in ¼" (6 mm), diameters of 3" (75 mm)

    Hot wire TIG produces consistent quality welds at high production rates. The process pre heats the wire prior to transfer in an automated TIG process, virtually eliminating porosity by driving off most of the volatile contamination from the surface of the wire. By preheating the wire it also allows for faster deposition rates up to 14 lbs. per hour. The process is spatter free and maximizes control of dilution, bead width and surface profile.

    The system is integrated to a fully mechanized system with PC based control and manipulation of circumferential or linear motion. Development of the process head is usually part specific.
