MrHwy17 Report post Posted June 23, 2013 I need to repair a hinge. What are the precautions for arc welding on metal that is attached to the frame? Share this post Link to post Share on other sites

hermanmullins Report post Posted June 24, 2013 What Brett said plus: What is the alloy of your chassis? What is the alloy of the hinge? As far as the process I would use a TIG machine. You can control the heat and heat effected area. Also remove every thing from the compartment and have a fire extinguisher ready. And last but not least, use a professional welder.
