16.9 Chapter Conclusion
Cameron Kjeldgaard
Summary
This chapter has explored the building blocks of blueprints and technical drawings. The various lines, different types of views, and the various notes and tables used to convey information. The way prints are drawn is highly varied, but what has been explained in this chapter are common conventions used across a variety of industries.
We have also explored the basics of the AWS welding symbol system, and NDE symbols. These symbols provide an excellent way for engineers and designers to convey a lot of information in a compact way. Interpreting these symbols is a continuous and daily task for any welder.
