Description

溶接トーチ3は、ノズル31およびコンタクトチップ32を備えており、たとえば多関節ロボット(図略)によって保持されている。ノズル31は、たとえば銅などの金属からなる筒状部材であり、適宜水冷構造を有している。コンタクトチップ32は、たとえば銅などの金属からなり貫通孔が形成されている。この貫通孔には、消耗電極としての溶接ワイヤWが挿通され、これにより、コンタクトチップ32は、溶接ワイヤWと導通している。コンタクトチップ32は、溶接母材P1,P2との間に溶接電圧Vを印加するための電極として機能するものである。なお、溶接トーチ3は、アーク溶接時には、図示しない多関節ロボットによって所定の速度で図1における紙面の奥行き方向または手前方向に移動される。 The welding torch 3 includes a nozzle 31 and a contact tip 32, and is held by, for example, an articulated robot (not shown). The nozzle 31 is a cylindrical member made of a metal such as copper, and has a water cooling structure as appropriate. The contact chip 32 is made of a metal such as copper and has a through hole formed therein. A welding wire W as a consumable electrode is inserted through the through-hole, whereby the contact tip 32 is electrically connected to the welding wire W. The contact tip 32 functions as an electrode for applying a welding voltage V between the welding base materials P1 and P2. Note that, during arc welding, the welding torch 3 is moved at a predetermined speed by a multi-joint robot (not shown) in the depth direction or the front side of the drawing in FIG.

ノズル31のコンタクトチップ32には、溶接電源1から溶接電圧Vが供給され、この溶接電圧Vの供給により、溶接ワイヤWから溶接母材P1,P2に対してアークACが発生される。なお、図1の符号40は溶融池を示す。 The contact tip 32 of the nozzle 31 is supplied with a welding voltage V from the welding power source 1, and the supply of the welding voltage V generates an arc AC from the welding wire W to the welding base materials P <b> 1 and P <b> 2. In addition, the code | symbol 40 of FIG. 1 shows a molten pool.

ワイヤ送給機構4は、溶接ワイヤWを溶接トーチに送給するための機構であり、図示しないワイヤリール、溶接ワイヤWを溶接トーチに対して送り出す一対の送給ローラ41、および送給ローラ41を回転させるワイヤ送給モータ42などによって構成されている。ワイヤ送給モータ42は、電源主回路11から伝達されるワイヤ送給速度指令信号Wfによって回転制御される。 The wire feeding mechanism 4 is a mechanism for feeding the welding wire W to the welding torch 3. A wire reel (not shown), a pair of feeding rollers 41 for feeding the welding wire W to the welding torch 3 , and a feeding A wire feeding motor 42 that rotates the roller 41 is used. The wire feed motor 42 is rotationally controlled by a wire feed speed command signal Wf transmitted from the power supply main circuit 11 .
