MONITORING AND CONTROL OF WELDING AND JOINING PROCESSES; AWS WHB-1 CH 11 AWS - American Welding Society An experienced skilled welder has highly sensitive sensors coupled with very significant processing capability, and can therefore accomplish a variety of important tasks, such as weld placement, weld joint tracking, weld size control, and control of the weld pool, among many others, with rel- ative ease. Using this feedback information, an experienced welder can assess the welding process with respect to its desired state, make minor changes in the weld parame- ters under his/her immediate control (e.g., weld current, voltage, travel speed and electrode orientation with respect to the joint path), and maintain proper torch orientation and distance in an effort to achieve the desired state of the weld. As human welders or opera- tors are relieved of the welding process control function in favor of computerized process control equipment, these process functions need to be evaluated to deter- mine if they can be automated to achieve the needed accuracy and reliability, as well as at what cost. Thus, sensors and computer processing equipment used to obtain, analyze, and con- trol the welding process must be durable and robust to be able to successfully perform in these environments. Welding process sen- sors obtain information about the welding process by converting physical phenomena from the input and pro- cess response variables into signals that can be utilized by monitoring or control equipment

Guide for the Joining of Solid Solution Austenitic Stainless Steels - 3rd Edition; AWS G2.3M/G2.3 AWS - American Welding Society This guide presents a description of solid solution austenitic stainless steels and the most commonly used welding processes and procedures for joining these materials. The most commonly used welding processes, including shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), gas metal arc welding (GMAW), submerged arc welding (SAW), and flux cored arc welding (FCAW), are discussed in detail; laser beam, electron beam, plasma arc, resistance, and braze welding are not covered in great detail. The welding processes discussed in this guide include recommended welding parameters, filler metals, shielding gases, and fluxes. Procedure qualifications, inspection and repair considerations and methods, and cleaning and safety considerations are also discussed. Practical information has been included as figures, tables, and graphs that should prove useful for determining the capabilities and limitations in the joining of austenitic stainless steels. This guide does not address martensitic, ferritic, or duplex stainless steels. Although this guide is not written with mandatory requirements, mandatory language, such as the use of “shall,” will be found in those portions of the document where failure to follow the instructions or procedures could produce inferior, misleading, or unsafe results.

Standard Method for Evaluating the Strength of Brazed Joints - Fifth Edition; AWS C3.2M/C3.2 AWS - American Welding Society The purpose of this standard is to describe the test methods used to obtain reliable data on the strength of metallic-to-metallic, metallic-to-nonmetallic, and nonmetallic-to-nonmetallic brazed joints. Test specimens preparation and testing is described to provide consistent and proper fabrication, brazing practices, and test results. Interpretation of the test results is the responsibility of the user. Documentation of the materials, brazing parameters, and test conditions are required to allow comparison of results with the joint strengths obtained by others using this standard method. General use of this standard method may permit a compilation of brazed joint strengths and brazing design criteria at some future time
