Resistance Spot Welding Power Supplies

Resistance Welding - also known as "spot welding" or "resistance spot welding" - is a thermo-electric process in which heat is generated at the interface of the metal parts to be joined by passing an electrical current through them for a precisely controlled time under controlled pressure.

Applications of resistance welding are vast - ranging from tiny spot welds on implantable medical devices to welding the enormous bolts on residential or commercial water heaters.  Both conductive and resistive materials may be joined using a resistance spot welder.  Resistance welding power supply selection is based on a number of criteria including material, the presence of plating, geometry and size of the parts to be welded, whether you need a spot weld or seam weld, the need for data collection and/or monitoring, available input power at your facility, and desired production rates.

Miyachi America offers a complete line of resistance spot welders including Linear DC, Inverter, AC and Capacitive Discharge.  A typical benchtop system would include a resistance welding power supply (spot welder), a resistance spot welding head, and a resistance welding monitor or weld checker.

Resistance Welding Systems

Miyachi America designs and builds fully integrated, turnkey semi-automated or fully automated resistance welding systems.  Our complete line of resistance welding controls, power supplies, weld heads, weld monitors and data acquisition equipment can be integrated with either PC- or PLC-based motion control systems.

Resistance Welding is a thermo-electric process in which heat is generated at the interface of two metal parts by passing an electric current through them for a precisely controlled time under controlled pressure. The metal is heated, melts, and quickly cools to form the bond or weld.

Applications of resistance welding range from tiny spot welds on electronic, automotive or medical parts, to welding the enormous bolts on residential water heaters.  Both resistive and conductive materials can be joined using resistance welding.  Resistance welding power supply selection is based on a number of criteria including material, the presence of plating, geometry and size of the parts to be welded, whether you need a spot weld or seam weld, the need for data collection and/or monitoring, available input power at your facility, and desired production rates.

Resistance Spot Welding Heads

Electrode pressure - also known as 'force' - is a key parameter in resistance welding.  Proper force guarantees both weld quality and consistency by improving fit-up of the parts being welded, thus increasing the current path and reducing interface resistance.  Force is provided by the weld head.

Miyachi America offers a full range of resistance welding heads including manual, air-actuated, and electromagnetic models with opposed, step, series, and parallel gap electrode configurations.  Force ranges from just .08lbs (40g) to 1600lbs (725.7kg) to address both fine and large scale spot welding applications.

Resistance Spot Welding Monitors & Checkers

Real time weld monitors - also called weld checkers - are invaluable tools for production monitoring, process development and weld quality analysis.  Weld monitors measure one or more of the electrical and/or mechanical parameters that dynamically change during the welding process including weld current, voltage drop across the electrodes, workpiece expansion and deformation, electrode force, electrode displacement (movement) and more.

Miyachi America offers a full range of desktop, hand-held and machine-mountable weld monitors / weld checkers, some with built-in printers or RS232 output.

Resistance Spot Welding Accessories

Spot welding applications require first and foremost a resistance welding control, but choosing the right accessories can enhance and improve your results and provide additional safety. These accessories can be broken down into a few basic but important categories: resistance welding handpieces, process observation and verification accessories like microscopes and pull testers, fume extraction, water chillers, footswitches, force gauges, electrodes and more.

Micro TIG Welding Power Supplies

Micro TIG (tungsten inert gas) welding, also known as gas tungsten arc welding (GTAW), is an arc welding process that uses a non-consumable tungsten electrode to produce the weld. TIG welding utlizes a constant current welding power supply to generate an electric arc between the tungsten electrode and the workpiece, using the resultant heat to create the weld.

The weld area is generally protected from atmospheric contamination by use of an inert shielding or cover gas (argon or helium).

Miyachi America's MAWA-300A micro TIG welder 
is ideal for welding coils and terminals, bus bars, and coated wires - applications commonly found in the automotive, medical, battery, and electronics industries.

Micro TIG Welding Accessories

Micro TIG welding applications require first and foremost a power supply and torch, but choosing the right accessories can enhance and improve your results and provide additional safety while working with the welder. These accessories can be broken down into a few basic but important categories: torches and electrodes, welding cables, safety, and gas handling. Find what you need here!

Laser Welding Power Supplies

Laser welding is a non-contact process which requires access to the weld zone from only one side of the parts being welded. The laser weld is formed as the intense laser light rapidly heats the material - typically calculated in milliseconds.

Three types of welds can be achieved with laser welding: conduction, conduction/penetration and penetration or 'keyhole.' Conduction welds are performed at low energy, resulting in wide, shallow weld nuggets. Conduction/penetration welds utilize a medium energy density and result in a deeper weld nugget. Penetration or keyhole welds are resultant of direct energy delivery into the material being welded resulting in deep, narrow nuggets.

As laser welding is a non-contact process, there are a great number of joint geometries that can be welded. The most significant requirement is that there be a close fit-up at the joint interfaces.  Laser welders can join a wide range of steels, nickel alloys, titanium, aluminum, and copper. As with other joining technologies, some materials are difficult to laser weld unless they meet specific characteristics, namely, reflectivity, the effect of high thermal cycling, and the vaporization of volatile alloying elements.

Laser Welding Systems

Miyachi America offers a complete range of turn-key semi-automated systems for laser welding, providing the fastest path from application concept to full production.

Successful laser manufacturing processes depend in large part on successful laser system integration.  Designers need to develop systems where the motion, laser, software, and tooling work properly and are integrated into a whole that supports the desired process flow.  Putting all the pieces together can be a challenge, compounded by the fact that many integrators don't understand lasers, and might have to rely on the laser manufacturer to integrate the system. Subsequently, if a problem arises, or if changes are needed to adjust to a new product, the integrator is in no position to modify or repair the laser system.

Miyachi America not only manufactures laser welders but also engineers and integrates laser systems, offering designers a one-stop shop for system integration. This includes running samples of the process in-house to ensure it does the entire job as specified, and answering in-depth application questions.

Laser Accessories

Laser based applications require first and foremost a laser, but choosing the right accessories can enhance and improve your results and provide additional safety while working with the laser. These accessories can be broken down into a few basic but important categories: laser diagnostic accessories such as power meters, process observation and verification accessories like microscopes and pull testers, laser safety accessories like laser safety goggles, fume extraction, water chillers, and opto-mechanical components such as lab jacks for use inside an enclosure.

Laser Marking Power Supplies

Laser Marking is a marking method which utilizes laser light to mark (ablate, melt, vaporize, or remove) materials using a fine spot diameter ranging from 0.002" to 0.01". The laser marks with short pulses (30 nanoseconds), providing precise control, and negligible heat input

A fast and clean technology, laser marking (also known as laser engraving or laser etching) is rapidly replacing older marking methods. A key factor in this widespread adoption is the exponential increase in the use of direct marking of part information to enable tracking and traceability across many industries, most notably medical device and automotive electronics manufacturing. Easy and flexible automation, improved environmental profile, and low cost of ownership add to the benefits of laser marking equipment or laser etching equipment.

Miyachi America's laser marking equipment product offering consists of fiber laser markers.  UV and CO2 laser markers are also available for integration into systems.

This includes running samples of the process in-house to ensure it does the entire job as specified, and answering in-depth application questions.

Laser Cutting Systems

Laser cutting is a non-contact process which utilizes a laser to cut materials for industrial applications, resulting in a high quality, dimensionally accurate cuts.  The process works by directing the laser beam through a nozzle to the workpiece.  A combination of heat and pressure creates the cutting action.

Laser cutting systems are rapidly emerging as the preferred choice for many fine laser cutting or machining applications, particularly when superior edge quality, tight dimensional tolerances and/or high volume production is required as in the medicalautomotiveelectronicsaerospace, and solar industries.  Solid state industrial lasers, which emit light at a short wavelength (typically near 1 micron), provide a reliable, stable energy source, have exceptional beam quality and are relatively easy to integrate into existing manufacturing production lines.  Laser cutting systems offer other advantages as compared to traditional cutting methods including the elimination of the need for hazardous waste removal and a smaller footprint.

Laser Micromachining Systems

Laser micro fabrication encompasses many processes including cutting, drilling, ablation, scribing and texturing.  The non-contact nature of the laser provides an excellent tool that can machine mechanically delicate parts without the application of force.  Micro fabrication or micro machining broadly covers the creation of features that are typically less than 0.02” (0.5mm) in depth and in many cases much less.

Laser micro fabrication systems using stages, scan heads and any combination of these are capable of machining highly accurate features.  Utilizing lasers from 10604nm to 355nm and pulse widths from microsecond, nanosecond, picosecond and femtosecond - a wide variety of materials including metals, plastics, ceramics and glass can be processed for industries including medical, aerospace, electronics and automotive.
