Resistance Welders
Resistance welding is the science of joining two or more metal parts together in a localised area by the pplication of heat and pressure. The heat is produced by the resistance of the material to carry a high amperage current. This heat is controlled via time application and level of current applied. The pressure is applied to forge the joint and consolidate the nugget to provide the weld strength. No extraneous materials such as rods, fluxes, inert gasses, oxygen, or acetylene are required.

Weld control comprises of a standard package featuring 5 independent programmes, 1/2 -100 cycle, upslope, pulsation mode, dual weld facility, squeeze, hold, cool, weld On/Off and mains isolator. Digital synchronous weld timing gives accurate repeatable weld periods resulting in minimum transient conditions and improved welds. Alternate half cycle is included for the welding of precious metals and special applications. High resolution heat control is provided, combined with a three position tap switch giving extremely fine adjustment of weld current over its entire range.
An alternative advanced timer/monitor can be supplied which has full SPC capability and 16 separate weld programmes with upslope, dual heat, internal storage for 8000 welds and many other features.
FPE's range of controllers allow for complete control of the weld parameter including:
• Pre weld squeeze time
• Up slope of weld power
• Weld Time
• Weld power
• Number of pulses
• Time between pulses
• Post weld forge time

What is Resistance Welding?
Resistance welding is the science of joining two or more metal parts together in a localised area by the application of heat and pressure.
The heat is produced by the resistance of the material to carry a high amperage current.
The greater the path of resistance is, the higher the heat intensity.
This heat is controlled via time application and level of current applied.
The pressure is applied to forge the joint and consolidate the nugget to provide the weld strength.
No extraneous materials such as rods, fluxes, inert gasses, oxygen, or acetylene are required.
FPE and Gatwick Fusions range of Friction Welders are suitable for the following industries:
• AEROSPACE
• AUTOMOTIVE
• CUTTING TOOLS
• ELECTRICAL
• INDUSTRIAL
• OIL AND ROCK EXPLORATION
• WHITE GOODS
