Welding Cart
Modeled in Solidworks for Makers. Each part individually designed with material considerations for both final functionality and ease of assembly.
All parts fabricated from hot rolled mild steel. Descaled using angle grinder and flap discs. Frame cut from 1”x1”x1/8” square tube with angle grinder and metal cutoff wheel. Fitment and welding prep achieved through bench grinder.
Frame welded at 85-95 amps with 1/16” filler rod and 1/16” E3 electrode. Frame base and 1/8” mild steel sheet baseplate welded separately with 1/8” filler rod for ease of final assembly.
3/8” mild steel plate tabletop welded to frame with 1/8” filler rod and 1/8” E3 electrode at 105-115 amps. Final assembly included instillation of caster wheels and eye bolt anchors for gas canister chains. Finishing was accomplished through surface conditioning tool as well as Scotch Brite discs and angle grinder.
Final Thoughts & Project Files
The cart deviates from the original design in two major ways- the expanded metal backplate for gas cylinder storage was replaced by steel pipe running horizontally, and the drawer space remains unfinished. Both of these changes were due to material costs.
Most difficulties encountered through fabrication were problems associated with metal warpage, especially prominent on the baseplate. More tack welds, clamps, and heat management could help alleviate these issues.
