AWS D14.3/D14.3M:2019 provides standards for producing structural welds used in the manufacture of earthmoving, construction, and agricultural equipment. Such equipment is defined as self-propelled, on- and off-highway machinery and associated implements. Manufacturers responsibilities are presented as they relate to the welding practices that have been proven successful within the industry in the production of weldments on this equipment. Basic dimensional weld details are defined and interpreted for application throughout the document. Provisions are made to identify base metals used in these weldments. Procedures to assure they are welded with compatible, identifiable welding processes and consumables are included with consideration given to factors that affect weldability.
