Simultaneous Welding
Simultaneous welding is a welding method where multiple laser beams are applied simultaneously to symmetry axes to neutralize distortion forces and increase component stability.
Physical-Chemical Mechanism of Action
In simultaneous welding, multiple laser beams are directed at the symmetry axes of a part at the same time. This ensures that distortion forces are balanced in all directions and the part remains stable during the welding process.
Metallurgical Relevance & Welding Risks
Applying multiple laser beams simultaneously prevents distortion forces from putting uneven stress on the part. This reduces the likelihood of cracks and strains in the weld. However, incorrect use or inaccurate symmetry can lead to uneven distortion forces, which in turn can cause part deformation or cracking.
Shop Practice & Action Guidelines
To successfully perform simultaneous welding, the laser beams must be precisely aligned with the part's symmetry axes. The beam intensity and duration should be set to ensure even heating and weld formation. For complex parts, it's advisable to do a test run before actual welding to determine the optimal beam positions.
