Hey Welder123,without any previous experience in welding plastics,obviously a training program is an excellent place to start.Thermoplastic materials and Thermosetting materials will be discussed.The latter being less forgiving.The welding process is comperable to GTAW in that hand eye coordination in conjunction with filler material addition is critical.But the process is much simpler.Joint make up is also comperable. A welding gun is used,employing the use of electricity and compressed air or an inert gas.A number of tips are avalable for tacking,root passes,hot passes and caps,depending on joint make up and manufactors specs.Your training program should give you what you need to have welding like a pro in 30 hours or less.Good luck and watch the color. gascupwalker1
