Overview
The following project encompasses the investigation of the requirement of a suitable beam and carry out weld design to secure the denoted baseplate. A beam is to be selected with restrictions upon volumetric dimensions highlighted in sections below. Selection process is documented in the report.
Furthermore, this investigation will include the justification of the selected beam to minimise various properties of the beam through methods of analysis. Finally, this investigation will also justify the weld profile and size of the beam.
This investigation will include the justification of the selected beam to minimise various undesirable effects of loads and ensure security while balancing cost and manufacturing process through a method of analysis. The specific final values will include a weld profile and specifications.
Approach
The selected weld for the structure depicted has been a Rectangular Hollow Section, from analysis.
Can be easily joined and able of the C450PLUS structure and the physical properties display its effectiveness in achieving the project to withstand changing loads and requirements.
Cannot be damaged by insects, rot or fire. The thinnest section is 6mm thick, and calculations show that the weld should be no smaller than 2/3 the thickness of the beam material, in this case 4mm.
The minimum required weld leg length is 5.46mm, hence, a weld leg length of between 10mm to 15mm is suitable.
The weld on the base plate to the beam is larger due to the larger bending component involved.
The weld profile for the selected system is to be recommended a tee joint with double bevel. To prioritise cost, a butt weld can also be utilized for the system.
