Flash Removal

The flash curl generated during welding is coherent, will not flake off, and can often be left intact if design and engineering considerations allow. Alternatively, parts can frequently be designed to accommodate the flash curl in a recess (flash trap).

In many cases, if the weld flash must be removed, this can be accomplished on the welder as an integral part of the machine cycle. Part geometry and accessibility of the flash are the two major factors that determine whether on-machine flash removal can be incorporated, and which system can be employed.
