15.7 Chapter Conclusion

Cameron Kjeldgaard

Summary

The focus of this chapter was to equip the reader with the ability to look at and communicate about welding in a professional manner. A hobbyist or do-it-yourselfer may not need all this terminology to make a small project or execute a simple repair.

However, in a professional welding environment, where your welding must meet specific requirements, identifying and being able to communicate about welding positions, weld types, and specific features of a weld is often necessary to a productive workday and successful career.
