This document summarizes a seminar presentation on orbital arc welding. It discusses the history of orbital welding which was developed in the 1960s by the aerospace and nuclear industries. It then covers topics like orbital pipe welding components and process, pipe materials, seam tracking, types of grooves, orbital welding types and advantages over manual welding. Applications are discussed for various industries. Future studies aim to develop faster welding and sensing systems. In conclusion, orbital welding provides higher welding speeds and joint quality compared to manual welding.

 ONE OPERATOR CAN CONTROL ONE OR
MORE MACHINE
 PORTABLE,ACCESSIBLE,FAST,PRECISE
 HIGHER WELDING SPEED
 LOWER DISTORTION
 LOWER HEAT AFFECTED ZONE(HAZ)
 HIGHER PRODUCTIVITY
 LOW SCRAP

13. APPLICATION
19 September 2015KKWIEER13
 OIL AND GAS
 FOOD INDUSTRY
 PULP AND PAPER
 CHEMICAL INDUSTRY
 DAIRY AND BEVERAGE
 WATER FILTARATION PLANT

14. FUTURE STUDIES
19 September 2015KKWIEER14
 faster welding process as well as faster sensing
system with cheaper mechanism
 Advanced orbital pipe welding system consists of
welding processes and sensing systems which
together make the welding process adaptive.

15. CONCLUSION
19 September 2015KKWIEER15
 Orbital system, speed of root pass welding is
higher than manual welding and this is the key for
cost reduction in pipeline application.
 Orbital pipe welding technique could yield in
significant reductions in the processing time,
skilled welder, and welding costs but
improvements in the joint quality.
