①后退引弧运条法在焊接开始点的10~20mm前方引弧后,向焊接开始点后退再熔敷焊道的方法。②对称法从焊接线纵向的中间,向两端进行对称的焊接方法。③摆动运条将焊条大体上垂直于焊接方向,一边往复移动,一边焊接的运条方法。④阶梯形多层焊多层焊时,一边从中间堆焊,一边向左右进行焊接的方法。⑤焊道间温度多道焊时,下一焊道开始前的焊道最低温度。一焊道一焊层时的焊道间温度称为层间温度。⑥飞溅损失因飞溅而产生的金属损失。⑦临时焊接临时进行起吊土具和定位板的焊接。这些工具在焊接产品完成后去除,最后不留在产品上。
① Backward Arc Arc method In the welding start point of 10 ~ 20mm front arc, to the welding start point and then re-weld the weld method. ② symmetry from the middle of the longitudinal weld line, to both ends of the symmetrical welding method. ③ swing movement of the electrode is generally perpendicular to the welding direction, while moving back and forth, while the welding method of transport. ④ ladder-shaped multi-layer welding Multi-layer welding, while surfacing from the middle, while welding left and right approach. ⑤ weld bead temperature of multi-pass welding, the next before the start of the bead weld the lowest temperature. A weld bead when the temperature between the weld bead is called the interlayer temperature. ⑥ splash loss caused by the splash of metal loss. ⑦ Temporary welding temporary lifting gear and positioning plate welding. These tools are removed after the welding product is completed, and finally do not remain on the product.
