PROBLEM TO BE SOLVED: To provide a resin composition having high flowability during molding and giving an injection molding with high welding properties at a joint part thereof which is problematic in the conventional nylon resin; and to provide a molding thereof. SOLUTION: The polyamide resin composition includes, based on 100 pts.wt. of a polyamide resin (A) having a melting point of≥230°C, 0.1-20 pts.wt. of a polyamide oligomer (B) containing 15-30 carbon atoms per amide group and having a number average molecular weight of 3,000-7,000. A process for producing an injection welding molding utilizes the polyamide resin composition. COPYRIGHT: (C)2011,JPO&INPIT
