A road map for grinding and finishing stainless steel

Oct 07, 2020 · Imagine a fabricator lands a contract involving critical stainless steel fabrication. Sheet metal and tubular sections flow through cutting, bending, and welding, then land at the finishing station. The part consists of a plate welded vertically to a tube. The weld looks OK, but its not the stack-of-dimes perfection the customer is looking for. CN102950369A - Method for welding 42CrMo alloy steel The invention belongs to the technical field of machining, and provides a method for welding a 42CrMo alloy steel herringbone gear in order to eliminate a welding crack between a 42CrMo gear ring and an A235-A web plate. The method comprises the steps of:machining the herringbone gear; welding a transition layer; carrying out post-welding treatment; and assembling and welding the web plate

  • Carbon EquivalentsWelding Parameters / PreheatingEffective Heat Input/ Cooling TimePeak Hardness in The Heat-Affected ZoneThe carbon equivalents are simplified parameters which try to estimate the influence of the alloying content of a steel by summarising the content of the various alloying elements by a particular averaging procedure. Plenty of carbon equivalents have been developed until now with different suitability for a special welding situation and steel grade. The four carbon equivalents the most common are calculated here (in weight-%):Fill in the alloying contents given in your inspection certificate.
