ELENA IV

ELENA® IV longitudinal seam welders (bench-type seam welders) have been developed for internal welding of workpieces with high hygienic requirements for container interiors. Applicable welding methods are TIG and micro plasma. The dual-acting pneumatic cassette clamping system also allows for clamping of workpieces with outward flanges.

Advantages of welding from the inside:

With TIG welding in a butt joint, a basic melting process occurs on the underside of the weld only. In such cases an unsettled seam root with slight edge chamfering may occur with thicker metals (approx. 0.5 mm or above) due to surface tension of the fused material, regardless of the quality of the cut metal edge. On the top of the seam, however, the welding arc will produce a clean, smooth and uniform surface. 

Special hygienic requirements, e.g. in baking ovens or food transportation containers do not allow even for the finest chamfering or burrs on the inside of the product since food residue may get stuck there. Win such cases, welding from inside to outside is helpful since the smooth and even seam surface is then on the inside of the product - the side which comes into contact with food and other substances.

ELENA® IV longitudinal seam welders therefore ensure smooth, uniform and visually perfect TIG welding seams on the product inside without causing more stringent requirements regarding the quality of the cut metal edge and without secondary machining.
