Achieving the perfect welding seam

High quality when preparing edges is decisive for perfect welding joints.  But which procedure  is best suited, and under which conditions? Many comparisons have shown that the reciprocal cutting tool technology developed by TRUMPF is a good choice for many assignments. Using the bevellers is extremely simple, reliable and safe. That makes operations profitable and guarantees cut edges that are always bright and free of oxides.

Reliable principle
There are several processes available to bevel edges prior to welding. These include grinding,  milling  and  using  the  cutting wheel. But for almost fifty years now, the leader has been the so-called cutting tool principle.  Developed  by  Prof.  Berthold Leibinger, it sets high standards especially in terms of quality, economy and safety, benchmarks that are not reached by other tools and machines.

The devices known as the TRUMPF TruTool TKF bevellers will thus be found in  every  industry  where  high-quality, absolutely  reliable  welds  are  needed. “Our tools are used in steel, metal, marine and automotive engineering just as in the manufacture  of  hazmat  containers  and other tanks,” mentions Johannes Wetzel, sales manager for the Power Tools Division at TRUMPF, listing just a few significant industries.

Flexible, safe, clean
Machining  with  the  TruTool  TKF creates neither dust nor vapours nor gases. Nor is much heat developed. That eliminates any  changes  in  the  metal  structure  and precludes chemical processes. The material is chipped away uniformly, making touch-up work unnecessary. Minimum roughness and a surface that is bright and oxide-free form the basis for flawless welds and for joins that can withstand extreme loading.

A further asset of these bevellers is that they are extremely flexible in use. No matter whether you’re  working straight sheet metal edges, outside radii or inside curves, a single pass is sufficient. Neither do pipes nor tubes nor small workpieces present a problem. Over and above that,users appreciate  the fact that they can employ these TRUMPF tools wherever they might be needed – either in the shop or out on a construction site.

Efficient solution
Especially the TruTool TKF 700, weighing  in  at  just  5.4  kilograms,  is  a real lightweight and can be used almost anywhere, for almost any purpose. It can create bevels up to seven millimetres in width and can be used on sheet metal as much as 20 millimetres thick. The angle grinder is an alternative to this machine and it may be quite suitable for users who have to weld only a few meters per week. Whenever this kind of work is encountered more frequently, investing in the TruTool TKF 700 is definitely worthwhile. To avoid adverse effects on health, protective clothing has to be worn when grinding edges.

Moreover,  the  risk  of  accidents  is high and the economy of this process is questionable. This is because the grinding disks’ short service lives and the relatively slow advancing speed of less than one meter per minute mean high operating expenses and labour costs. Johannes Wetzel names some other disadvantages of grinding: “The quality is not uniform; it depends on the worker’s  skills  and  performance  and  on external influences, as well. The amount of heat generated during machining makes it impossible to create bright cutting edges and may make reworking necessary.”

Suiting every quality need
Quality  problems  like  these  are essentially eliminated wheHombre
