The automatic argon arc girth welding method of the pipeline, the specific steps of which are as follows:
The processing of step 1. metal ring: internal diameter is chosen and the metal pipe that docks pipeline outer diameter and match, turning metal tube
Sub- inside and outside wall, being processed into wall thickness is 0.3~0.6mm, and width is the metal ring of 1.5~2.5mm；
Step 2. scribing line, assembly: crossing in the outer wall middle position of metal ring, as Weld pipe mill position, then will
Round metal ring set is in docking pipeline commissure；
Step 3. tack welding: using symmetrically positioning from welding process for manual argon arc welding, metal ring is fixed on docking
Commissure；
Step 4. boxing: using automatic argon arc girth welding to boxing is carried out at metal ring butt weld, docking pipeline is realized
Welding.
The processing internal diameter is in 14~16mm, welding current: 55A~65A, welds revolving speed: 2.3~2.5rpm.
7, the automatic argon arc girth welding method of pipeline according to claim 5, which is characterized in that the processing internal diameter exists
When 34~36mm, welding current: 110A~130A welds revolving speed: 1.5~1.7rpm.
Tube interior gas flow is not more than the 50% of pipe extraneous gas flow.
Technical effect of the invention: pipeline single-piece of the present invention directlys adopt docking structure, and preset certain in weld seam outer ring
The metal ring of thickness and width guarantees the forming requirements of weld seam front and back sides, to effectively simplify conventional tube for welding filling
The connector design requirement of road boxing improves production efficiency.
Detailed description of the invention
Fig. 1 is the step connected structure of conventional tube boxing.
Fig. 2 is the pipeline joint structure of metal ring socket.
