One of the most difficult processes associated with continuous production of HF longitudinally welded tubes is removal of the internal weld bead. Limited space, lack of access to the tool, severe internal soiling, and the hot welding flash itself, combine to complicate the use of inside tube scarfing systems. Increasingly stringent tube industry requirements for clean, accurately shaped cost-effective welding flash removal dictate the design standards for our high precision tools. Individual welding system differences necessitate customization of our ID scarfing solutions to your local installation. For this reason, close interaction with you – throughout development, commissioning and ultimate application – is particularly important to us.
