An improved polyamide resin composition for weldable moulded articles which comprises: (a) 99.9-30 % by weight of a polyamide-containing compound; (b) 0.1-20 % by weight of a plasticizing compound selected from the group consisting of esters of low molecular weight poly(ethylene glycol) having the formula (I): R-COO-(CH2CH2O)n-OC-R wherein R is a branched or straight chain alkyl group having from 1 to 40 carbon atoms, and n is 2 to 20; or long chain alkyl polyester of formula (II): HOOC-R-CO-(O-R'-O-CO-R-CO)n-O-R'-OH wherein R is alkyl of 16 to 45 carbon atoms, R' is alkyl of 2 to 6 carbon atoms, or, wherein R is an alkyl of 2 to 6 carbon atoms, R' is an alkyl of 16 to 45 carbon atoms, and n is 2 to 50.
