Сварное соединение, полученное лазерной сваркой множества наложенных друг на друга металлических листов, содержащее три или более сварных валиков в форме кольца или разомкнутого кольца, причем поверхностная твердость сварных валиков увеличивается в направлении от внутреннего валика к внешнему валику.
2. Способ лазерной сварки, включающий наложение друг на друга множества металлических листов и формирование множества сварных валиков в форме кольца или разомкнутого кольца для сваривания вместе наложенных металлических листов путем облучения лазером, содержащий этапы:
- формирования первого сварного валика в форме кольца или разомкнутого кольца путем облучения лазером, и
- последовательного формирования путем облучения лазером дополнительных двух или более сварных валиков в форме кольца или разомкнутого кольца в направлении изнутри наружу снаружи упомянутого первого сварного валика.
