Copper tip clamping fingers

Copper tipped, aluminum hold down fingers are standard on all HANYAN seam Welders. The copper tipped hold down fingers assist in the chilling the weld joint. Copper tooling absorbs and dissipates heat through the use of additional thermal mass, operating under pressure against work piece.

Back-up insert

Inserts are quickly and easily interchanged into the backup mandrel to accommodate a variety of material types and thicknesses. Copper inserts dissipate heat generated during the welding process.

Additional inserts are available to cover a wide range of material types and thicknesses. Inserts are available with or without gas back-up capabilities.

Back-up Mandrel

Designed to support the part being welded and hold the back-up inserts.

Droop mandrels are available to ease loading and unloading of parts.

Optional water cooled mandrels are available.

Fixed and removable riser options

Seam welder base can be modified to accommodate larger diameter parts.
