Macro etching; an etch test consists of cutting a specimen transverse to the weld axis, applying an etching solution of 5% nitric acid and inspecting the exposed surface. This form of destructive testing is an excellent method of determining the soundness of weld metal and the metallurgical structure produced by the weld. #HodgeFabulous | Hodge Fabrication, Inc.

See a detailed article along with several other mig welding videos at http://www.weldingtipsandtricks.com/mig-welding-wire-speed.html and visit my online store at https://weldmongerstore.com/ The Cut and Etch test aka Macro Etch test is often overlooked and underused. Its a destructive test so can be used on live parts but it provides valuable information on your mig welding technique and settings. Cut with a zip disc, bandsaw, portaband, or whatever and then just smooth with a flap disc and som
