The invention discloses an automatic pulsating MIG aluminium bronze surfacing method for upstream and downstream flanges. The method is realized in the way that a movable welding robot conducts automatic pulsating MIG aluminium bronze surfacing on the inner surfaces of the fixed upstream and downstream flanges. By using the robot teaching welding gun motion trails, welding gun nozzle heights and angles, a first welded joint of a priming coat is welded by means of robot teaching, and welded joints apart from the first welded joint of the priming coat can be automatically operated by setting welded joint offset dimensions and welding gun angles. By adoption of the technological method disclosed in the invention, pumped storage upstream and downstream flange aluminium bronze surfacing can beachieved, welding universality and operability are greatly improved, the quality of the welded joints can be effectively improved and production efficiency is also improved. 本发明公开一种上下游法兰自动化脉冲MIG堆焊铝青铜方法，通过可移动的焊接机器人在固定的上下游法兰内表面
