Testing Welds - Did it Penetrate? The macro etch test is a very valuable test to verify or check for penetration. It is especially valuable when developing a procedure or welding technique. Since it only tests one cross section, it is not always conclusive unless multiple cuts are done for a good sampling. Carbon Steel and Aluminum are relatively easy to etch but other more corrosion resistant alloys like stainless, nickel, titanium, and cobalt alloys require specific etchants and sometimes requ

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.

In-Situ SEM Material Testing: Micro-Tensile Testing The macro tensile test (macrotraction), while providing valuable information about the general properties of the material, determines the average of the effects of each constituent present in the matrix, such as the different phases or interfaces. To quantify the properties of a single phase or interface, microtraction tests are required, as shown in the video. In addition, by further reducing the dimensions of the specimens, unique mechanisms

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
