Weld Pool And Weld Bead. Figure 39 shows one frame from a sequence of radiographic images of a molten pool of a bead-on-plate no weld joint weld taken during submerged arc welding. Arc pressure acts on the weld pool surface in the normal direction de pressing the molten deposit.

The flux has the same protective function as a shielding gas has in MIG and TIG welding. Adjust the parameters to a lower setting so the weld pool is less fluid and more able to fill in the joint. The proposed method was verified with bead-onplate welding experiments.
The length of the molten pool and bead size were higher for.
The image is positive therefore a thinner section of the depressed weld pool is represented as a lighter area. When the width of the upper bead width W f is 479 mm the ratio of this width to bead width W f W b is 091. The weld pool must be carried along the joint in a consistent width and depth and the motion used to carry the weld pool has a direct effect on the quality of the weld bead. This creates a wide and shallow molten pool.
