Tow eyes - Transpec

WeldingWeld-in drawbar eyes• The mounting of such drawbar eyes can be carried out by using differentwelding seams. All welding connections are to be performed according to theregulations of the manufacturers of drawbars, poles, towing rods and/orchassis and to be checked when vehicle is approved.• As minimum requirement for welding we recommend Y 42 20 (according toDIN 8559) when using inert gas, i.e. E 43 30 (according to DIN 1913) whenusing welding electrodes.• Extract of the original DIN 74053 and 74054:“Generally parts with dynamic strength of more than 30mm thickness of steelquality ST 52-3, before welding should be normalised at approx. 900 degreesC, for the process of welding at approx. 250 degrees C treated and afterwelding at approx. 600 degrees C annealed for releasing stresses(normalising by the manufacturer/ preheat in the welding department/annealing for releasing stresses can be cancelled without lessening the stresscapacities).On welding the drawbar eye on the drawbar, the shaft of the drawbar shouldbe pre-heated with neutral Oxy-Acetylene-Flame to approx. 250 degreess C.”40mm weld-in tow eye11
