SEAM Welding of MA8 Alloy with Hermetically Sealed Seams

摘要

During roller welding of magnesium alloys it is necessary to avoid overheating of sheet surface, leading to the formation of cracks, reduction in corrosion resistance and disruption of seam hermeticity. To obtain extended joints, possessing high density, use double row seams; when selecting the welding system consideration must be given to the geometric characteristics of the item. Electrodes with intensive internal water cooling are employed. (Author)
