OTHER DATAPreheating: is not required for welds in sections up to 20 mm but risk of porosity can be reduced by preheatingsections over 10 mm. Preheating temperature is usually 150-200 °C.Clean material is essential for a good weld quality. Remove oxide, dirt, oil, humidity etc. before welding. Ifbrushing use a stainless steel wire brush.The wire is not recommended when a good matching of colour is required between the welded joint and thebase material after anodic treatment.Product Data SheetOK Tigrod 4043Prepared byQualified byApproved byReg noCancellingReg datePageMats LindeTero TolonenMichael SpießEN006175EN0050662013-08-292 (2)
