手工电弧焊接时,如何全部用完整根焊条而不留下约占焊条全长10～15%的焊条头,是一个很有意义的问题。梁彦德同志在技术科室的帮助下,最先学习和掌握了无焊条头焊接法的先进技术。这种焊接的特点是:采用一种专用的焊把,焊条上全部涂药而不露端头,焊条不是夹在焊钳的钳口中,而 Manual arc welding, how to use all the full root electrode without leaving about the full length of the electrode 10 ~ 15% of the first, is a very significant issue. With the help of technical departments, Comrade Liang Yande first learned and mastered the advanced technology of welding without welding head. The characteristics of this welding is: the use of a special welding rod, the electrode coating all without leaving the tip, the electrode is not caught in the clamp jaws, and
