Scarfing Tools

Aviruddha Productivity is an official representative of ‘’SAAR- HARTMETALL GmbH’’ Germany in the Indian market, introduces high-quality ID and OD scarfing tools, for removal of inside and outside scarf. The Welding Impeders, Notching tools, Ferrite rods, Cutting Ring Holders, and complete systems used for manufacture tubes and pipes with longitudinal weld seams, all produced inhouse and supplied across the globe.

Process

Quality requirements for tubes and pipes with longitudinal weld seams have become increasingly more demanding. This has led to a higher demand of different scarfing tools for inside as well as outside scarfing.

The base material, sheet metal, comes in the form of a coil. Here are the different steps in forming tubes and pipes:

If required: edge trimming to optimize even edges, roll forming, welding (mostly high frequency welding), deburring, calibrating, sometimes sizing and cutting to length. Since these steps are all a continuous process, the goal is to avoid interruptions.

The most economical way to scarf a longitudinal weld seam is to remove it during the manufacturing process. For this purpose, you will usually find OD scarfing tools mounted to at least one of the first stands past the weld point. For ID scarfing of tubes and pipes the mounting unit needs to be set up before the weld point.

A mounting unit is used to hold the tow bar with an integrated or attached impeder (cluster impeder) which runs underneath the weld point. The ID scarfing tool is attached to the tow bar. The actual scarfing tool, the cutting ring, is pressed against the weld bead to remove the bead.

The intention is to remove the weld bead on the outside and/or the inside and create a smooth surface.

Services

• Production of scarfing tools and tool holders – all made by the same manufacturer with matching tolerances.
• All scarfing systems and tools can be incorporated into tube mills of most manufacturers and of almost all sizes.
• Together with the customer, the selection of the perfect scarfing tools and operating parameters for existing conditions.
• Use of different carbide grades and coatings to match respective requirements.
• By using our impeders the welding process can be adapted and optimised. For this purpose, we also offer a high pressure pump for the cooling liquid with a filtering function.
• Training the stuff with regards to the use and handling of our tools.

Our complete ID-scarfing and OD-scarfing systems consist of all of the components you’ll need for high-efficiency tube and pipe production.
