BHLM-1500 Longmen straight ring seam automatic welding machine
Equipment use:
Application of workpiece diameter less than with 1500mm, the length is less than or equal to 6000mm tank, container, pipeline and automatic seam automatic girth welding; specification according to the use requirements.
Equipment composition:
Longmen type welding machine + drive roller group + NC welding swing system, +PLC control system + man-machine conversation operation system + elliptical arc automatic tracking system + welding power supply
Workflow:
The workpiece in support, adjust the welding position, welding parameter, welding torch, button up, start running in automatic arc welding, arc welding, rise - out of work.
Welding process:
- argon arc (TIG/ wire TIG)
Gas (GMAW).
- argon arc + gas (TIG/ wire TIG+GMAW)
- argon arc + submerged arc (TIG/ wire TIG+SAW)
- gas + submerged arc (GMAW+SAW)
- argon arc gas shielded arc + + (TIG/ TIG+GMAW+SAW)
Others
Welding quality:
Butt welding and backing welding can realize single side welding, double face forming and weld height control;
Butt welds meet radiographic testing or ultrasonic testing. The pass rate of grade I or II welds is over 98%;
Requirements for mechanical properties such as impact, tensile and bending are met
Angle welding meets the requirements of welding angle height and pressure test
