This chapter discusses various factors that affect corrosion of stainless steel weldments. It begins by providing an overview of the metallurgical factors associated with welding. This is followed by a discussion on preferential attack associated with weld metal precipitates in austenitic stainless steels as well as several forms of corrosion associated with welding. The effects of gas-tungsten arc weld shielding gas composition and heat-tint oxides on corrosion resistance are then covered. Microbiological corrosion of butt welds in water tanks is also illustrated. In addition, the chapter provides information on corrosion of ferritic and duplex stainless steel weldments.

This appendix discusses the sizing, scaling, and configuration requirements of the basic components in a quench cooling system, including tanks, pumps, hoses, and inlet and outlet fixtures and the materials from which they are made.

This chapter discusses the quenching process and its adaptation to induction heat treating. It describes the three stages of quenching, the cooling characteristics of various types of quenchants, and the details of nearly a dozen compatible quenching methods. It also explains how to verify whether a quenchant can cool a workpiece fast enough to achieve martensitic transformation without cracking or distortion.

This chapter reviews the major marine applications of stainless steels, including the desalination equipment, shipping containers, and heat exchangers that handle seawater.

This chapter is a detailed account of major sources of stray current that can cause corrosion and discusses several ways to prevent damage from stray-current corrosion.

Besides the induction coil and workpiece, the induction generator (source of ac power) is probably the most important component of an overall induction heating system. Such equipment is typically rated in terms of its frequency and maximum output power (in kilowatts). This chapter addresses the selection of power supplies in terms of these two factors as well as the operational features of different types of sources. The six different types of power supplies for induction heating applications covered in this chapter are line-frequency supplies, frequency multipliers, motor-generators, solid-state (static) inverters, spark-gap converters, and radio-frequency power supplies. The chapter discusses the design and characteristics of each of the various types of power supplies.

This chapter discusses the maintenance needs of major components in induction heat-treating systems, including power supplies, heat stations, capacitors, high-frequency output stages, induction coils, water systems, quench systems, and fixturing.

This chapter discusses the basic components in an induction heat treating system. It describes the design and operating characteristics of power supplies, load-matching transformers, tuning capacitors, power regulators, controllers, process monitors, and diagnostic systems. It also provides information on fixtures and work-handling devices, quench systems, and load matching and tuning procedures.

This chapter discusses some of the ways that the lessons learned from failures have benefitted society, leading to improved product designs, better materials, safer industrial processes, and more robust codes and standards. It also provides several examples of how the technology and procedures associated with aviation security have been upgraded in the wake of air disasters.

This chapter describes issues related to corrosion of carbon steel weldments and remedial measures that have proven successful in specific cases. The forms of corrosion covered includes preferential heat affected zone corrosion, preferential weld metal corrosion, and galvanic corrosion. Industrial case studies demonstrating the necessity for testing each galvanic couple in the environment for which it is intended are presented. The chapter also discusses various factors associated with stress-corrosion cracking in oil refineries.

Stainless steel powders are usually made by water or gas atomization. This chapter describes both processes and the properties and characteristics of the powders they produce. It also discusses secondary processes, including drying, screening, annealing, and lubricating, and the effects of iron contamination on corrosion resistance.
