 ---------------------------------- 
 High-manganese steel is the carbon content of 0.9% to 1.3%, manganese content of 11.0% to 14.0% of the steel, that ZGMn13. 
 This material is between 1000 ~ 1100 ℃ in a single austenite, in order to maintain this organization require high-temperature quenching, 
 That in 1100 ~ 1050 ℃ temperature range between the immediate water quenching to room temperature. After heat treatment of high-manganese steel, if re-heated to 250 ℃ or more, 
 There will be carbide precipitation, its fragility, and then there is this large linear expansion coefficient of the material, prone to greater stress, 
 If the conventional welding process welding cracking phenomenon occurs due to slow cooling after welding to 950 ~ 250 ℃ temperature range, 
 A large number of carbide precipitation, so that the base metal embrittlement, internal stress again, check the cooling between weld and base metal have been cracking. Resolve this problem, 
 Necessary according to the special nature of this material, take a special welding process, to take intermittent welding, cooled to room temperature immediately after welding method, the weld area to avoid the period of temperature. 
 The result is successful. ZGMn13 poor welding of high manganese steel, welding the main problem is: ⑴ carbide precipitation heat-affected zone of high manganese steel tough after 1050 ℃ water treatment, 
 All the solid solution of carbon in austenite at room temperature showed a single-phase austenite, good toughness, but when re-heated above 250 ℃, the carbon will precipitate along the grain boundary carbides, 
 Greatly decreased the material's toughness, so after welding, the heat affected zone of a section within the carbide precipitation will be different degrees, not only the loss of toughness, brittle, 
 But also reduce the wear resistance and impact toughness. Solution is to speed up the measures welding weldment when the cooling rate, shorten the time spent at high temperatures to reduce carbide precipitation. 
 ⑵ serious ZGMn13 hot cracking tendency of the linear expansion coefficient of high-manganese steel is 1.6 times of low carbon steel, but the thermal conductivity rate is low carbon steel, 1 / 6, so the weld will have a huge stress, 
 In the S, P under the action of harmful impurities, resulting in weld heat-affected zone hot cracking and liquefied cracks. Strict control measures to solve the base metal in the S, P content, 
 Welding materials, especially in the S, P content; followed by hammer welding and other technological measures used to reduce welding stresses. 
 How to correctly use ZGMn13 welding of austenitic high-manganese steel welding material? ⑴ for ZGMn13 austenitic high-manganese steel electrode welding electrode for low-carbon steel welding core 
 And adding appropriate amount of skin in drug alloying elements, so that the deposited metal to get high-manganese steel of chemical composition and mechanical properties. For welding austenitic high-manganese steel electrodes ZGMn13 There are two types: 
 One is the high-manganese steel type electrode D256 (EDMn-A-16) and (EDMn-B-16), mainly used for welding by the severe impact of abrasive wear parts, such as jaw crusher plates, etc.; 
 The other is the Cr-Mn type electrode D276 (EDCrMo-B-16) and D277 (EDCrMo-B-15), the deposited metal-mediated steady state in high-manganese austenitic, 
 When, after a strong impact into martensite, mainly used for welding of cavitation-resistant or high-manganese steel surfacing, such as turbine blades, excavator bucket teeth and so on. 
 ⑵ ZGMn13 austenitic high-manganese steel welding wire with a wire with Mn-Ni, Mn-Cr, Mn-Mo, Mo-Ni-Cr system high-manganese steel wire, and Cr-Ni, Cr-Ni-Mn system alloy steel wire, 
 Its chemical composition, see Table 31. Cr-Ni wire system not only has high corrosion resistance, impact load to the speed of sound can be hardening, 
 But also welding of high manganese steel and carbon steel or low alloy steel allow heterogeneous high dilution, can be used as high manganese steel and carbon steel welding filler materials. 
 ZGMn13 austenitic high-manganese steel welding process. Welding or soldering ZGMn13 austenitic high-manganese steel, they should focus on the use of heat, little heat input welding method, 
 Such as arc welding, MIG welding gases, etc., is not recommended to use gas welding and TIG welding. Welding or soldering process: 1) must be cleaned before welding at the welding dirt, 
 Grease and rust, carefully check from the floor, cracks, sand, porosity and shrinkage defects. If these defects, we must use wheel or arc gouging shovel out. 
 Abrasive wear of parts must be rubbed off the hardened layer, because the hardened layer of metal is very sensitive to the crack. 2) should not be preheated before welding, multi-layer welding temperature should not exceed 300 ℃, 
 To prevent overheating the heat affected zone embrittlement. 3) The welding wire as much as possible the use of small energy, base metals to minimize the heat, take measures to speed up the connection as much as possible the cooling. 
 To this end, with a short arc, DC reverse polarity, stitch welding, weld a short section, gap welding, pulse welding and other process measures, the use of these measures will reduce to some extent, carbide precipitation. 
 4) To prevent hot cracking, can be used Cr-Mn or Cr-Ni austenitic steel electrode backing. If the low-carbon steel or low alloy steel welding on austenitic high-manganese steel ZGMn13 when 
 Welding can be a layer of Cr-Ni or Cr-Mn austenitic steel weld for isolation to prevent cracks. 5) post-weld stress for the elimination of welding, the welding zone can be pointed hammer hammer. 
 In order to be deposited metal austenite, after hammering the weld area quickly spray cooling. 
 Mn13, X120Mn12 plate thickness of 6-30 common specifications, special specifications thinnest up to 1.0mm, 
 Thickest 100.0mm. A small round spot. Be the top high-manganese steel square steel bar steel.
