AWS D14.1 (Industrial, Mill Cranes, and Other Material Handling Equipment)

AWS D14.1’s implementation into ProWrite allows users the ability to enter, store, and access their Welding Specifications for Welding of Industrial and Mill Cranes and Other Material Handling Equipment

documents as well as their welders from within ProWrite Welding Software.

AWS D14.1 is the Welding Specifications for Welding of Industrial and Mill Cranes and Other Material Handling Equipment welding code developed by The American Welding Society for construction of these components.

This specification applies to the welding of all principal structural weldments and all primary welds used in the manufacture of cranes for industrial, mill, power house, and nuclear facilities. Furthermore, the specification applies to other overhead material handling machinery and equipment that support and transport loads within the design rating, vertically or horizontally, during normal operations, and, when agreed upon between the Owner and Manufacturer, to loading caused by abnormal operations or environmental events, such as seismic loading. 

Secondary welds that will be subjected to tensile stresses of less than 5000 psi [34.5 MPa] need only meet the requirements of Section 7, Workmanship, and Section 10, Weld Quality and Inspection. The engineering drawings shall specify the joint detail, type, and size of weld. This specification is not intended for application to construction- or crawler-type cranes. For the welding of rails, refer to AWS D15.2, Recommended Practice for the Welding of Rails and Related Rail Components for Use by Rail Vehicles. 

All provisions of this specification are equally applicable to the strengthening and repairing of existing overhead cranes and material handling equipment as described above.
