PRECISION TIG WELDING RESISTANCE MICRO WELDING EQUIPMENT CONSULTANCY

PRODUCT CATOLOG

COMPANY PROFILE VBCIE (ASIA) Pte Ltd is a business of VBC Instrument Engineering based in UK that designs and manufactures special purpose welding equipment for the most challenging applications. We are the Asia office for the proprietary VBC Instrument Engineering Heat Management System (HMS) TIG welding equipment designed for the welding of the most challenging materials and thin section welding. We are focusing on the sales & marketing as well as after sales support for VBC Instrument Engineering products in Asia.

HMS INTERPULSE TECHNOLOGY

The InterPulse gas tungsten constricted arc welding (GTCAW) process of the VBC Instrument Engineering is an advanced modification of conventional GTAW, using magnetic constriction and high frequency (20,000Hz) modulation of the arc waveform to produce a constricted arc and greatly reduce the overall heat input during welding. The technique allows titanium and its alloys to be successfully welded outside of a vacuum chamber, without a trailing gas shield, and thus with far greater versatility and precision than conventional processes.

Working Principle of InterPulse Technology

i. Right Hand Rule

The right hand rule is a useful mnemonic for visualizing the direction of a magnetic force as given by the Lorentz force law. The force is in the opposite direction for a negative charge moving in the direction shown.

ii. Arc Constriction

The weld arc is constricted by the magnetic field around the arc. The VBC InterPulse generates high frequency pulses, the relationships of which are programmable to alter the magnetic field of the arc, thus enabling the control of the constriction of the arc.

To illustrate the differences of the constricted arc of InterPulse technology against the conventional inverter power source, some pictures were taken during trails on titanium welds using a fast video camera.

The photos above clearly shows the constricted arc of the InterPulse which results in reduced heat input and heat affect zone which will greatly improve the weld quality comparatively with a Inverter TIG welding source. The InterPulse process produce restricted heat input welds without the massively high cooling rates

associated with electron beam and laser welding, which frequently lead to martensite formation, is a major advantage. The picture below illustrates the superior weld quality of InterPulse vs Inverter welding source

The HMS InterPulse process is capable of high precision and control during welding because the advanced arc waveforms of the InterPulse can be tailored to control the macro and microstructures as well as textures and microtextures in the weld fusion zone. It is well known that mechanical properties of weldments are controlled by their microstructures.

In summary, HMS InterPulse is a comparatively easier weld process to control, with excellent capability to weld Nickel based super alloys and titanium materials and definitely more cost effective.

Interpulse Technology > IE 60i

The IE60i is the next generation of low heat input TIG welding sets. Following in the footsteps of the famous

InterPulse range of power sources, the IE60i uses the latest technology to assist the welder reduce the heat input and energy that is required to perform quality welds on some of the most difficult alloys in use today.

• Some of the materials that are being welded daily within the aerospace and related industries with this technology are: CMSX-10, Inconel 738, 713, 625, C263, PK33, MAR-M 247 René 80, René 142, and

Titanium without a chamber or trailing gas shield. • The precise electromagnet fields created by the ultra fast power supply control of the arc

characteristics, which can be programmed to minimise the Heat Affected Zone and the width of the arc.

• These systems offers new levels of weld quality and control over the inverter technology. • The benefit of this technique is that increased arc force or penetration is achieved with a lower input

current. • This allows for improved heat management on critical welds whist still attaining full penetration. Also,

when adding filler wire the dilution in the weld pool is reduced with benefits also seen in the final microstructure.

• This is particularly useful when welding demanding single and directiinterpulse 150

• Interpulse 150onal crystal components.

Controls • Easy to use four line backlit display. • Keyswitch access to programs prevents accidental erasure of data. • Set-up pushbutton allows the weld sequence to run without an arc. • Sequence start/stop via weld torch switch, foot pedal or remote input.

Standard Model • Conventional pulse on/off

• 128 Program storage & Memory module storage • Manual/step/timed weld functions

• All systems supplied as a complete to suit the application. • eg torch, foot pedal, start/stop switch. • Primarily designed for manual, Robot and CNC interfaces are available. • 175 Amp single phase version.
