Weldability 20MnVS6 hollow bar can be readily welded using all conventional methods. Welds should be completed without interruption. For fillet welds, a multi-pass technique should be selected. Stress relieving is generally not necessary. In case of WT>12mm preheating to 150-200°C is recommended. St52.0 hollow bar can be readily welded using manual and automatic methods. Preheating and/or stress relieving are generally not required, though may be necessary in the case of WT >30mm. For 20MnVS6 and St52.0 basic welding consumables are recommended.
