| Instruction
E6013 is the carbon steel rods with a coating containing 30% TiO. The electrode welds stable on both DC and AC, suited for all positions, is easy to weld and re-strike, spatter minor, and weld seams are bright and smooth. Application To weld low carbon steel structure. Particularly for thin plates up to 15mm, for spot welding and overlay welding for smooth surfaces. |

Now technology for Φ2.0mm 6013:
A Φ2.0mm 6013 aluminum alloy plate was selected for single-mode fiber laser welding process test, and a 3D response was constructed with laser power, welding speed, and defocusing amount as input variables, and front-back fusion width, back-to-width ratio and cross-sectional area of fusion zone as output variables.
The model is significant and fits well. The influence of process parameter changes on the geometric characteristics of welded joints is analyzed, and the microstructure and mechanical properties of typical welds are analyzed.
The results show that the laser power is positively correlated with the back fusion width, back width ratio and the change of the cross-sectional area of the fusion zone; the welding speed is negatively correlated with the output variable; the defocus amount is positively correlated with the front fusion width and the change of the cross-sectional area of the fusion zone. The change in width ratio is negatively correlated. In the back-to-width ratio regression model, there is an obvious interaction between the laser power and the defocus amount.
The single-mode fiber laser can achieve full penetration of 2 mm 6013 aluminum alloy under the process matching of low power and high welding speed, and the welding joint cross-section melting width is narrower, the microscopic grain size is small, and its tensile strength and section elongation are different. It is 315.5 MPa and 12.3%, which can reach 90% and 42% of the base metal.
