Abstract
PURPOSE: To control the potential heat quantity of a welding wire, increase the deposition amount per unit welding length and obtain a uniform joint part by adjusting length and diameter of a consumable electrode to the specific relation in the full- circumference welding of cylindrical bodies.
CONSTITUTION: In performing gas shielded arc welding of the circumferential joint of the cylindrical structures which are fixed in an inclined or horizontal posture, L/D2≥20 is desirable if the protruding length and diameter of a consumable electrode are denoted as L and D respectively. Below 20 of L/D2, it may be employed depending upon cases, but the effect is low. Above 40, the wire end becomes red heat and the arc becomes unstable, making the continuation of welding difficult. D≤2.4mm is desirable and above this, the are rigidity becomes lower and if too small, high speed feedability degrades. Further, current density is desirably 70W 700A/mm2 and it is recommended to set this in approximately inverse proportional to D.
