掩护电孤焊接;气保护金属极电弧焊;保护式电弧焊
For this reason the author decide to put forward a metal cored self-shielded flux-cored wire, in this way the author expect to ameliorate the problem of welding fume and increase the welding efficiency.
为此笔者提出了金属粉芯自保护药芯焊丝构想,以此改善自保护药芯焊丝烟尘较大的问题和提高焊接效率。
During this subject research the author mainly investigate and examine the self-shielded mechanism base on mix metal powder such as C-Mn-Si or C-Al-Si, which without fluoride and produce little slag and fume during welding.
笔者在本课题研究中着重论证并考察了C-Mn-Si与C-Al-Si等不含氟化物主要依靠合金元素实现的非造渣型自保护机制。
