Before welding.

If possible, the edges of the parts are trimmed, beveled and cleaned. To obtain an even and clean surface of the edges, they are sometimes machined on edge planing and end milling machines.

Size of current

Increasing the current increases the depth of weld, if manual arc welding involves a weld depth of more than 75% of the thickness of the welded metal, dramatically changing the conditions for heat transfer from the bottom of the weld pool and can occur through penetration of the metal. The lighter the metal, the lower its density, the deeper the weld.

Current Polarity

The greatest depth of penetration is obtained by welding with DC current of reversed polarity. At direct polarity weld depth is 40-50% less, and when welding with alternating current - less by 15-20% than when welding with direct current of reversed polarity.
