SPOT WELDING

The Gatwick® Technologies range of resistance spot and projection welding machines provides laboratory
quality and production line dependability for low capital investment.
All the mechanical and electrical characteristics of the welding
machines have been carefully studied in relation to practical production
requirements, the result being a range of designs that are eminently
suitable for precision metal assembly. Production Engineers will notice
that the interchangeability of the top and bottom electrode systems
simplifies set-up procedures and gives overall versatility for handling
difficult welding configurations whilst still maintaining a consistent
reliable welding action. These features, coupled with the excellent work
area, visibility and ease of operation, makes Gatwick® Technologies welding machines an ideal choice.


SEAM WELDING

The seam welding process uses an undriven upper electrode wheel. The lower mandrel assembly is
mounted on a horizontal slide with variable speed drive. The wheel will
commence welding at the start of the weld joint and continue to weld
until the end of the weld joint. Weld spacing, spot size and weld speed
are readily adjustable.

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.

Gatwick’s range of controllers allow for complete control of the weld parameters 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 process

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.

Gatwick® Technologies’ range of Resistance Welders is suitable for the following industries:

  • AEROSPACE
  • AUTOMOTIVE
  • CUTTING TOOLS
  • ELECTRICAL
  • INDUSTRIAL
  • OIL AND ROCK EXPLORATION
  • WHITE GOODS
