Abstract:
A laser-welded shape section steel includes a web member and a flange member each made of a steel plate, the steel plate having an equivalent carbon content C eql  of not less than 0.075 and not more than 0.15, the equivalent carbon content C eql  being represented by the following formula: C eql =C+(Si/50)+(Mn/25)+(P/2)+(Cr/25)+Ti, where a welded part, which is a joint part in which the web member and the flange member are joined, has a hardness of not less than 1.2 times and not more than 4 times as hard as that of the steel plate, and the welded part a protrusion length of not greater than 1 mm.

Claim (Index 3):
A method of producing a laser-welded section shape steel including a web member and a flange member each made of a steel plate, the method comprising the step of:\n joining the web member to the flange member by carrying out laser welding, the laser-welded section shape steel satisfying the following conditions (a) and (b): (a) the steel plate having an equivalent carbon content C eql  of not less than 0.075 and not more than 0.15, the equivalent carbon content C eql  being represented by following Formula (1): C eql = C + Si 50 + Mn 25 + P 2 + Cr 25 + Ti ( 1 ) (b) a welded part, which is a joint part in which the web member and the flange member are joined, having a hardness of not less than 1.2 times and not more than 4 times as hard as that the steel plate, and lengths \u03b1, \u03b2, \u03b3, and \u03b4 being not greater than 1 mm, where (i) a side of the web member, which side has been irradiated with laser light is referred to as a front side, (ii) the welded part protrudes, by the length \u03b1, from the flange member on the front side of the web member, (iii) the welded part protrudes, by the length \u03b3, from the front side of the web member, (iv) the welded part protrudes, by the length \u03b2, from the flange member on a back side of the web member, and (v) the welded part protrudes, by the length \u03b4, from the back side of the web member.
