Upgrading off-road vehicles, restoration work and repairs often involve welding, brazing and metal fabrication. Discussion includes welding processes, how-to techniques, projects and chassis fabrication. Whether your project is a MIG trailer frame, a roll cage built in 4130 or a cast iron repair on a vintage engine or transmission casting, share your experiences and welding tips here.
Fusing molten metal requires chemical compatibility! Understanding metallurgy takes welding to the professional level and provides safer, more predictable welds and finished products. Choosing the right filler material for welding and brazing is an important step when forming quality bonding and welding. Automotive welding projects often require metal "normalizing" before welding. After welding, post-weld heat treatment is often necessary. Ask questions and share experiences here!
