Handbook of Mold, Tool and Die Repair Welding covers an important and frequently overlooked area of welding—the repair of molds, tools and dies.
Because two rather different trades overlap in this process—welding and tool making, the materials and techniques involved have tended to be obscured.
For many years, toolmakers and tool users have had to rely on the small number of specialist welders who do understand exactly what welding repair involves and have the skills to carry it out.
Understanding the technical side of tool steels is frequently a problem for welders and understanding the practical side of welding can be a problem for machinists.
Handbook of Mold, Tool and Die Repair Welding has been written so that specialists from both sides can get to grips with the techniques and procedures involved.
