Oct 11, 2020 · The outcomes indicated that the weld region is comprised of complex microstructures such as Widmanstatten ferrite, ferrite with or without carbide aggregates and grain boundary ferrite. The most hardness within the stir zone reached as much as about 347 HVdue to the stable state transformations and grain refinement.Why is low carbon steel can be welded?Therefore, this type of steel has the worst weldability, so it is not used in general welding structures and is only used for repair welding or surfacing of castings. After welding, the welded parts should be tempered to eliminate stress, then to fix the organization to prevent cracks and improve the performance of the weld.See all results for this questionWhy Low Carbon Steel Can Be Welded, High Carbon Steel Medium carbon steel has good hot working and cutting performance, but poor welding performance. Its strength and hardness are higher than low carbon steel, while plasticity and toughness are lower than low carbon steel. It can directly use cold-rolled material, cold-drawn material after heat treatment without heat treatment,.
What's the effect of welding on high strength steel?
The effect of different welding process on naval grade High Strength Low Alloy steel (HSLA) was studied and found that weld metal was comparatively stronger than the base metal.See all results for this questionWhat is the effect of welding on mechanical and microstructural?The elongation in base metal, PAW joints, CCGTAW joint and PCGTAW joint was 12 %, 7.5 %, 4.5 % and 6.2 % respectively, which means there is reduction in ductility by 62 % and 48 % in CCGTA and PCGTAW respectively. In SMAW and GMAW the reduction in ductility were 30 % and 39 % respectively  .See all results for this questionWhat are the mechanical properties of weld joints?The mechanical properties of weld joints have also been affected by filler material composition and type of welding used. Finally, out of all the welding processes friction welding and laser welding led to superior quality compared to other fusion welding.

Afsari; Content type: Technical Paper; Published: 25 June 2016; Pages: 1193 - 1198THE EFFECT OF WELDING ON MECHANICAL AND A research was done on low carbon steel plate (SAE 1020 steel) to see the effect of coarse initial grain size and heat input on microstructure using heat input for welding as 0.5, 1 and 2 kJ/mm and concluded that lower heat input (0.5 KJ/mm) resulted in maximum hardness due Nucleation Effect of Ca-Oxysulfide Inclusions of Low microstructural analysis of hot rolled low carbon steel Plasma weldingIn order to achieve excellent toughness of heat affected zone (HAZ) of low carbon steel plates by welding, several microstructure control techniques using fine particles have been developed. In particular, Ca-oxysulfide inclusions have been used in a lot of steel plate products, because they are thermally stable even in near the fusion line of weld joint and they have grain refining effect in HAZ.
