Profile member and method for manufacturing thereof

A method for manufacturing a profile member for a suspended ceiling system, comprising

• forming a sheet metal material into an elongate T-shaped profile member with a web having two web side walls and a pair of oppositely disposed flanges projecting from a bottom portion of the web, and
• laser welding the elongate T-shaped profile member for providing a laser weld joint extending straight in a longitudinal direction of the T-shaped profile member and joining the two web side walls to each other, characterized in that
• the step of laser welding comprises alternatingly performing a first operation and a second operation,
• whereby a laser weld joint is provided comprising a plurality of welded first sections associated to the first operation and a plurality of welded second sections associated to the second operation, wherein the welded first sections and welded second sections are alternatingly arranged along the extension of the laser weld joint,
• wherein laser welding is applied continuously in the first operation and not continuously in the second operation,
• wherein an energy level that each application of laser welding reaches during the second operation is below an energy level that each application of laser welding reaches during the first operation.
