Jan 03, 2014 · Is a welder permitted to mechanically grind down a weld that that does not meet the acceptance criteria for D1.1 on its weld profile? If the weld remained at or above flush, (unless it was detailed with a spec for min reinforcement) no further welding would be required after dressing it to meet surface profile requirements.
Example: You are welding a flush patch into a presure vessel under ASME code: the weld MUST be smoothed such that there are no points where there is a sharp groove, and there are no points whre there is a slope grearer the 1:3 from the nominal surface. If this can be done without grinding (and it often can) then no grinding is required.

Jun 03, 2013 · The act of grinding can be deceivingly simple. But the devil''s in the details. Effective grinding requires operators to apply enough pressure at the correct angle to let the grains—the "cutting tool" of a grinding disc—remove the most metal in the shortest time, while not prematurely wearing the disc or burning out the grinding tool.
Bevel both sides & weld with 7018 will be fine. If you positively need penetration then after welding the first side root, flip it over & grind out the second side till your into the first weld. Then weld it up alternating sides to minimize pulling. The real question you
While it has many useful appliions, the welding process can inadvertently weaken equipment by imparting residual stresses into a material, leading to reduced material properties. In order to ensure the material strength of a part is retained after welding, a process known as Post Weld Heat Treatment (PWHT) is regularly performed. PWHT can be

The process of welding galvanized steel is commonly found in the metal fabriing industry. Many welders usually weld galvanized steel at some point in their career and in doing so they may experience galvanize poisoning or metal fume fever. Galvanize poisoning is a condition that results from the over exposure to zinc oxide.
