<p>PROBLEM TO BE SOLVED: To provide a welding method of a martensitic stainless steel thin strip capable of easily securing a high toughness welding part with excellent workability. SOLUTION: A welding method of a martensitic stainless steel thin strip by irradiating a pulse laser to a butted part of the martensitic stainless steel thin strip consisting of more than 2 percent, by mass, of a carbon equivalent=C %+Mn%/6+Si%/24+Ni%/40+Cr%/5+Mo%/4+V%/14, and by irradiating the pulse laser equivalent to 1 pulse at the initial period with high energy density and the later period with low energy density.</p> |
