Abstract
Objects to be welded are joined together by laser welding to form adjacent nuggets. When a distance between central axes of the adjacent nuggets is p and a diameter of the adjacent nuggets in the objects to be welded is d, the adjacent nuggets are formed so as to satisfy an equation 1.0<p/d≤1.6.
Claims6
A welding method comprising:
- joining together a plurality of objects to be welded by forming adjacent nuggets in the plurality of objects to be welded by laser welding, the adjacent nuggets being formed on an imaginary straight line or on an imaginary open curved line,
- wherein a distance between central axes of the adjacent nuggets is p, a diameter of the adjacent nuggets in the plurality of objects to be welded is d, and the adjacent nuggets are formed so as to satisfy an equation 1.0<p/d≤1.4.
A welded structure comprising:
- a plurality of objects to be welded and joined together by laser welding, the plurality of objects having adjacent nuggets, the adjacent nuggets being formed on an imaginary straight line or on an imaginary open curved line,
- wherein a distance between central axes of the adjacent nuggets is p, a diameter of the adjacent nuggets in the plurality of objects to be welded is d, and an equation 1.0<p/d≤1.4 is satisfied.
