welding. This situation is illustrated in Figure 3. The figure shows two series of tests involving TIG orbital welding of stainless steel pipes that differ in terms of wall thickness and material. It illustrates clearly that the formation of temper colours differs despite having an identical residual oxygen level in each case. Stainless Steels Welding Guide - Lincoln Electricmartensitic stainless steels. Steels with over 0.20% C often require a post weld heat treatment to soften and toughen the weld. 3.3 AUSTENITIC STAINLESS STEEL The austenitic stainless steels contain 16-26% Cr, 8-24% Ni + Mn, up to 0.40% C and small amounts of a few other elements such as Mo, Ti, Nb (Cb) and Ta. The balance between the Cr and Ni

Welding Polarity Recommendations for TIG, MIG, And Stick When it comes to more serious welding applications, which include low alloy steels and pipe welding that needs higher strength, you can rely on this type of polarity. In addition to that, it is important to keep in mind that only the E6010 electrode is capable of this kind of welding application using the DC polarity.

Welding tool steel - The Fabricator

Jan 17, 2019 · The temperature around the weld puddle decreases with distance from it, so while some parts of the steel are expanding, others are already contracting. That creates distortion and cracking. Keep in mind that tool steels are medium- and high-carbon steels, which makes them susceptible to hardness after reaching high temperatures.Guide for Welding Mild Steel Pipe - AWS BookstoreJul 20, 2000 · welding.
