Specific implementation mode
The present invention will be further described with reference to the accompanying drawings.
- 6 are please referred to Fig.1, the manufacture welding method of box type rod piece of the invention includes the following steps：
Step S1, part setting-out, and using numerical control multi-head flame cutting machine carry out cutting stock, obtain bottom plate 1, top plate 2,
Diaphragm plate 3 and web 4.Certain allowance is placed according to part processing and welding requirements when setting-out.
Bottom plate 1, diaphragm plate 3 and two blocks of webs 4 are assembled into flute profile case by step S2.It specifically includes：By fixture by bottom plate
1 is horizontal fixed in group moulding bed；Vertically-mounted diaphragm plate 3 is fixed 3 bottom end of diaphragm plate is vertical with 1 surface of bottom plate；In tabula
Assemble web 4 in 3 both sides of plate.As shown in Figure 2.
Step S3 first welds the vertical position welding between diaphragm plate 3 and two blocks of webs 4, then welds between diaphragm plate 3 and bottom plate 1
Downhand welding.As shown in figure 3, indicating vertical position welding at A, downhand welding is indicated at B.
