Heavy steel, smooth milling with PEMA solutions
Milling with automated working sequences
Milling is crucial for all sectors that have heavy welding in their production
Milling increases production efficiency, saves welding time and significantly improves the welding quality.
Milling is the machining process where the material is removed while welding is the metal joining process. With strong welding automation experience Pemamek also has the know-how to optimize weld joint preparation specifically for welding process needs.
Milling with PEMA milling machines
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. Also, deformations and tensions are lower. Automatic depth controlling enables the groove to remain constant. 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.
Semi-narrow groove significantly decreases groove volume and total welding time, and back gouging is not needed anymore. A defect rate can be also decreased using the milled semi-narrow groove.
Conventional Thermal
Cutting
- Oxy-cutting for both bevels
- Welding of inside and outside bevel
- Possible arc gouging between welds
Welding preparation with PEMA milling
- Only oxy-cutting for inside bevel > Save time
- Outside milling > Reduce in defect rate
- Welding of semi-narrow groove > Less welding
