比较了四种脉冲电流波形（锯齿波、梯形波、前沿带冲刺的梯彤波和阶梯波）对焊缝成形的影响，提出阶梯波对全位置焊管的优越性。
By comparing the effect of four kinds of pulsed current wave forms ( zig-zag , trapezoid , trapezoid with sharp front impulse and step form ) on the formation of weld , we propose that step wave form has the best advantage for all position tube welding .
