Resilient Floor Welding with Leister
A welding rod, as recommended by the manufacturer, must be used when installing linoleum, rubber, PVC, or TPU surfaces. Welding rods are generally available with 3 to 5 mm diameters. Speak with your material manufacturer or supplier to find out more.
Before welding, the seam edges must be milled or grooved to approx. 2/3 of the thickness of the material. The welding rod is then welded into the groove to create a strong bond. It is important that the welding rod fully penetrates the milled groove otherwise the seam may fail prematurely.
The welding rod is then trimmed in two stages: The first pass is done with a trimming guide immediately after welding. This removes the bulk of the excess rod. The second pass is done once the material has cooled completely. This helps prevents concave seams, producing an even, flush seam with a long service life.
Welding in 4 Steps
Welding – preparation
A welding nozzle with a narrow air outlet is recommended to avoid damaging the surface of material near the seam. This damage only becomes visible after several cleaning cycles.
An automatic welder such as the UNIFLOOR or MINIFLOOR should be used for longer seams. Automatic welders produce more consistent welds at a faster speed. Short seams can be welded with a hand tool such as the TRIAC ST/AT or the HOT JET S.
