Armor steels are difficult to weld due to the high percentage of carbon. The coarse-grained area and the fusion line in the welded joint are sensitive areas due to the high hardness and the possible presence of hydrogen produced during the welding process. Furthermore. multi-purpose armored vehicles made of armored steel are exposed to dynamic loading due to traffic on rough terrain. https://allfixelectricales.shop/product-category/stove-rotary-switch/
