Monolithic tools are used for welding Butt joints or Lap joints.

Made from a single piece of either hot-worked tool steel or superalloy.

Available in large quantities for production jobs, or as one off tools for development work

Various combinations of features are available, including scrolled shoulders, probe flutes or flats, convex/concave shoulders.

Composite tools are comprised of a separate probe made from a specialist alloy, inserted into a shoulder made from a tool steel.

Enables use of a high value superalloy probe in a low cost tool steel shoulder. Can be used for welding Butt joints or Lap joints.

Available in large quantities for production jobs, or as one off tools for development work.

Various combinations of features are available, including scrolled shoulders, probe flutes or flats, convex/concave shoulders.

Adjustable composite tools have a separate probe supported by a control rod.

Allows for fine adjustment of probe length to suit material thickness.

Enables use of a high value superalloy probe in a low cost tool steel shoulder.

Available in large quantities for production jobs, or as one off tools for development work.

Various combinations of features are available, including scrolled shoulders, probe flutes or flats, convex/concave shoulders.

Retractable pin tools consist of an adjustable probe that is controlled independently to the shoulder.

Minimises formation of an exit hole at the end of the weld by retracting the probe as the shoulder approaches the end of the weld.

Allows the weld depth to be varied.

Require a specially equipped machine.
