The main points of operating vertical welding are: the current used should not be too large, slightly lower than the fillet welding current, and the size of the selected electrode should be determined according to the thickness of the welding piece.When welding, the arc should not be too large, but should be short arc welding.

The welding method shall be serrated or triangular.In the case of multilayer welding, the current should be lowered for the first time, and foreign matters such as drug skins should be cleaned for subsequent welding to reduce slag inclusion or Korean opacity.

Swing must be in place and evenly swing, otherwise the weld is not particularly good-looking, there may be bottom cut or big flash.

Vertical welding refers to welding from top to bottom or from bottom to top along the seam.Welding positions with inclinations of 90°(vertically up) and 270°(vertically down) are called vertical welding positions.Vertical welding is called vertical welding.

The operation of vertical welding stipulates that the current used shall not be too large, slightly lower than that of fillet welding, and the size of the selected electrode shall be determined according to the thickness of the welder.When welding, the arc should not be too large, but should be short arc welding.Welding method, using zigzag or triangle welding method.In the case of multilayer welding, the current of the first pass should be low, and foreign matters such as coating should be removed in the subsequent welding to reduce slag inclusion or incomplete welding.The details still need to be worked out.
