Crucial part of high quality welding Milling is a machining process that plays a crucial role in achieving high-quality welds. With its extensive experience in welding automation, Pemamek has the expertise to optimize weld joint preparation according to the specific requirements of the welding process. Pemamek’s milling machines are designed for circumferential and longitudinal welds – with milling, a semi-narrow groove decreases groove volume. Also, deformations and tensions are lower. Automatic depth controlling enables the groove to remain constant. Efficiency and precision for wind energy manufacturing Pemamek’s milling machines are designed for circumferential and longitudinal welds – with milling, a semi-narrow groove decreases groove volume, so a smaller amount of weld passes is required, and consumables can be saved. Automatic depth controlling enables the groove to remain constant. Also deformations and tensions are lower. Semi-narrow groove significantly decreases groove volume and total welding time, and back gouging is not needed anymore. For example in wind tower manufacturing, after the inside weld has been welded, the outside is milled a little bit over the inside weld, and the root is opened so back gouging can be avoided. PEMA milling technology • Save time -> Only oxy-cutting for inside bevel • Reduce in defect rate -> Outside milling • Less welding -> Welding of semi-narrow groove Conventional thermal cutting • Oxy-cutting for both bevels • Welding of inside and outside bevel • Possible arc gouging between welds
