The invention discloses a double-wire vertical welding method of a high-strength steel component by a robot. The method particularly includes the steps: firstly, machining a welding groove into an X-shaped groove; secondly, welding a base layer, a filling layer and a covering layer of a part to be welded by the aid of a double-wire pulsed gas metal arc welding method after the part to be welded isfixed in a spot welding manner. Two welding wires are arranged forwards and backwards along a welding direction when the base layer is welded, and the welding wires are parallelly arranged along thewelding direction when the filling layer and the covering layer are welded. According to the method, standards of qualified welding seams such as arc voltage and current are provided, the qualified welding seams are good in penetration degree and can be acquired at low cost by the method, molten pools of the qualified welding seams cannot drip, and welding efficiency can be remarkably improved. 本发明公开了种机器人双丝垂直立焊高强钢构件的焊接方法，具
