The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 and shown in Figure 2 be the conventional flange sheet: wherein 1 for round platform, and 2 is the pipeline step, pore centered by 3; Fig. 3 is the effect schematic diagram of conventional flange sheet and pipeline welding mode.
The manual aluminium soldering method of conventional tungsten electrode argon arc welding is: Outer Tube inserts the center pore to pipeline step (2), the more welding wire of striking arc carries out sintering to round platform (1) and pipeline outer wall then, generally all use the built-up welding mode to carry out welding operation, its effect built-up welding road (3) as shown in Figure 3.
