Laser welding has been increasingly used in the textile industry in recent years. It allows us to rapidly join the entire material in the line of joining, without gaps in the joint area. The LDPE film was welded using CO2 pulsed laser. We empirically searched for the best welding parameters and evaluated welds with tensile tests. We explored the influence of the weld geometry and the variation of parameters on the quality of the resulting weld. It turns out that universal welding parameters do not exist, but are dependent on the geometry of the welded joint, the material and type of supporting table.
