Title:
消耗溶接ワイヤを含むアーク溶接方法
Document Type and Number:
Japanese Patent JP7048816
Kind Code:
B2
Abstract:
The invention relates to an arc welding method using a consumable welding wire (1), wherein in successive welding cycles (SZ) during a welding process (Pi) a certain welding current (I(t)) is applied to the welding wire (1) and the welding wire is moved with a certain wire conveying speed (v(t)) towards a workpiece (2) to be processed. The aim of the invention is to further improve the stability of the welding method. The aim is achieved, according to the invention, in that in the event of a change of the welding process (P1) to a welding process (P2) with an increased mean wire conveying speed (vmean) during a welding cycle (SZ) and/or with an increased mean welding current (Imean) during a welding cycle (SZ), a lowering phase (AP) is initiated, wherein in the lowering phase (AP) the welding current (IA(t)) is lowered for a specified duration (ΔtA).
